FOREWARD
This document has previously been part of AAMA 800 Voluntary Specifications and Test
Methods for Sealants. These back bedding/glazing compounds may have other
applications within the fenestration industry however this specification primarily
addresses non-structural, in-shop glazing applications.
1.0 SCOPE
To provide a minimum level of performance for back bedding/glazing compounds that are
flowable, pumpable, or gunnable at application temperature.
1.1 Compounds shall be classified as:
802.3 (Type I)
802.3 (Type II)
805.2 (Group A)
805.2 (Group C)
Compounds may include single or multiple components at ambient or elevated
application temperatures.
1.2 Back bedding/glazing compounds are used to bed glass to the surrounding substrate
and are intended to remain ductile and prevent air infiltration and water leakage. 802.3
(Types I and II) Back Bedding/Glazing Compounds permit movement without loss of
bond and display cohesive failure when tested in a peel configuration. 805.2 (Groups A
and C) Back Bedding/Glazing Compound also permit movement without loss of bond but
require a higher minimum adhesive strength than 802.3 compounds and may be allowed
to display adhesive failure to the substrate.
1.2.1 802.3 Type I compounds have resistance to intermittent water contact.
1.2.2 803.2 Type II compounds have resistance to extended water contact, but not
continuous immersion.
1.2.3 805.2 Group A Compounds display adhesive failure based on laboratory testing.
NOTE 1: If there is any concern about adhesive failure, please consult the sealant
manufacturer for detailed performance history.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 2
1.2.4 805.2 Group C Compounds display a minimum of 90% cohesive failure based on
laboratory testing.
NOTE 2: Sealant manufacturers may choose to test sealants to any or all of the four
classifications.
NOTE 3: The use of lap shear testing following exposures is offered to meet the needs
of window manufacturers for sealant strength data which may be used for window design
and estimating strength after accelerated aging. This data may provide insight on sealant
durability and performance.
1.3 The primary units of measure in this document are metric. The values stated in SI
units are to be regarded as the standard. The values given in parentheses are for
reference only.

hardness on all three samples shall not exceed values in the following table:
COMPOUND MAXIMUM SHORE “A”
802.3 (Types I and II)
805.2 (Groups A and C)
55
70
5.3 Thin Film Integrity
There shall be no presence of voids within the compound in any of the three samples
when tested in accordance with Section 6.2.
5.4 Peel Adhesion
5.4.1 802.3 (Type I) Compound
All panels shall have at least a 90% cohesive failure of at least 0.88 N/mm (5 lbf/in) of
width when tested in accordance with ASTM C794 as modified in Section 6.3 (Test A).
5.4.2 802.3 (Type II) Compounds
All panels shall have at least a 90% cohesive failure of at least 0.88 N/mm (5 lbf/in) of
width when tested in accordance with ASTM C794 as modified in Section 6.3 (Test B)
both prior to and after water immersion.
5.4.3 805.2Group A Compounds
Materials shall be chemically curing and all panels shall have a peel strength of at least
2.2 N/mm (12.5 lbf/in) of width when tested in accordance with ASTM C794 as modified
in Section 6.3 (Test A). Materials displaying less than 90% cohesive failure are to be
designated as Group A compounds.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 6
5.4.4 Group C Compounds
All panels shall have at least a 90% cohesive failure of at least 2.2 N/mm (12.5 lbf/in) of
width when tested in accordance with ASTM C794 as modified in Section 6.3 (Test A).
Materials displaying 90% or more cohesive failure are to be designated as Group C
compounds.
5.5 Lap Shear Strength with Exposure
This is test method to serve as an alternate to peel adhesion for classification of 805.2 A
and 805.2 C groups only. Materials displaying less than 90% cohesive failure shall be
classified as Group 805.2 A. Materials displaying 90% or higher cohesive failure shall be
classified as Group 805.2 C.
When tested in accordance with ASTM C961 as modified in Section 6.4, the specimens
shall meet the following:
Samples 5a, 5b, 5c, 5d and 5e must have pull values of at least 207 kPa (30 psi).
NOTE 4: The 207 kPa (30 psi) minimum standard was derived as follows: Assuming a
(60 psf) trapezoidal load distribution on a “large lite” of 121.9 cm x 243.8 cm (48 in X 96
in), the maximum distributed load along the sealant bond line is 10 lbs/inch. Using a 1.27
cm (0.5 in) wide bond width (bite), the total stress on the sealant is 10 ÷ 0.5 = 20 psi. This
value was increased to 207 kPa (30psi) to provide a safety factor of 1.5 (consistent with
uniform structural load test requirements of AAMA/WDMA/CSA 101/I.S. 2/A440).
5.6 Slump
When tested in accordance with ASTM D2202 as modified in Section 6.5 the compound
shall have a slump less than 2.5 mm (0.1 in).
5.7 Vehicle Migration
There shall be no vehicle migration from the compound edge when tested in accordance
with ASTM D2203 as modified in Section 6.6. Contact stain through the filter paper is
allowable.
5.8 Low Temperature Flexibility
The compound when tested in accordance with ASTM C734 as modified in Section 6.7
shall not have cracks and/or loss of adhesion from the test panel.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 7
5.9 Water Resistance
There shall be no presence of voids, cracks, separation or breakdown of the compound
when tested in accordance with Section 6.8.

(1/4 in) thick.
6.2.1.8 Six weights, 910 g (2 lb) each.
6.2.2 SUBSTRATE PREPARATION
6.2.2.1 Clean the aluminum panels in Section 2.3.1.1 and the microscope slides by the
procedure outlined in Section 3.5.
6.2.3 SPECIMEN PREPARATION
Place two strips of 12 mm (1/2 in) masking tape on the face side of the aluminum test
panel surface. Position the strips parallel to each other using the panels long edges as
guides. These strips shall run the entire length of the panel. [The tape in position on each
side of the face side shall be approximately 0.18 mm (0.007 in) thick and will serve as the
0.18 mm (0.007 in) spacer.]
Place two more strips of 12 mm (1/2 in) tape on top of the applied tape. Position this tape
so that it is one-half the length of the panel. [This double thickness of tape will serve as
the 0.36 mm (0.014 in) spacer.]
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 9
Apply two 3 mm (1/8 in) diameter beads (perpendicular to the tape) of test compound
approximately 25 mm (1 in) long to the test panel. The two beads shall be applied parallel
to each other and shall be spaced 25 mm (1 in) and 56 mm (2 1/4 in) from one end of the
panel. [These beads shall be between two sections of the tape either 0.18 mm (0.007 in)
thick or 0.36 mm (0.014 in) thick.]
Repeat this application using the opposite end of the panel for spacing requirements.
Holding a microscope slide by its ends, carefully place it on one bead of sealant and
gently press down until some resistance is felt. Do not attempt to force the slide down to
contact the tape and avoid any rocking or sliding motion while pressing. Repeat the
application of a slide to each of the remaining three beads. Set the assembly on a level
surface and lay a rigid plate over the slides. Set a 910 g (2 lb) weight on the plate in order
to press and hold the assembly for 24 hours at 25°C ± 3°C (77°F ± 5°F). At the end of the
24 hours, remove the weight and plate and allow the assembly to cure undisturbed for an
additional six days at 25°C ± 3°C (77°F ± 5°F). Prepare a total of six specimens by this
procedure.

6.3.4 Test Procedures
6.3.4.1 Immediately following the specimen exposures described in Section 6.3.3, allow
the specimens B and D to be conditioned to 25°C ± 3°C (77°F ± 5°F) for a minimum of
one hour or until the specimen temperature measures 25°C ± 3°C (77°F ± 5°F). When all
specimens have reached 25°C ± 3°C (77°F ± 5°F), make two cuts per panel with a sharp
blade, cutting completely through to the substrate surface and being careful not to cut the
peel cloth strip. Cuts shall be exactly 25 mm (1 in) apart.
6.3.4.2 Test A
Cover the sealant with a polyethylene strip before placing in the tensile testing machine.
This will allow the material coated peel strip to be pulled parallel (or 180° to the sealant)
at a rate of 50 mm (2 in) per minute. Peel the sealant approximately 12 mm (1/2 in) and
then cut sealant to the substrate to which it is attached. (Undercut the compound to

6.7 TEST METHOD FOR LOW TEMPERATURE FLEXIBILITY
AAMA 800-XX, DRAFT #2, DATED 6/3/15 Page 23
6.7.1 Use ASTM C734 to prepare test specimens using three standard etched and anodized (AA M10C
22A 31) aluminum panels 85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 0.1 mm (1/32 in) thick and template
consisting of an aluminum or brass frame with inside dimensions of 130 mm (5 in) x 40 mm (1 1/2 in) x 6
mm (1/4 in) thick.
6.7.2 Allow test specimens to air dry for seven days at 25°C ± 3°C (77°F ± 5°F). Place the three panels in
air circulating oven for 14 days maintaining temperature at 82°C ± 3°C (180°F ± 5°F). Remove the panels
from oven and allow specimens time to reach ambient temperature. Place the assembly in deep freeze
and maintain a -14°C ± 1°C (7°F ± 2°F) for 24 hours along with a 25 mm (1 in) steel mandrel
approximately 200 mm (8 in) long. While still in the deep freeze, place each specimen in turn on the
mandrel with the aluminum plate next to the mandrel, and without holding the sealant bend the specimen
180° around the mandrel within one second.
6.8 TEST METHOD FOR WATER RESISTANCE
6.8.1 Materials Required
6.8.1.1 Three standard etched and anodized (AA M10 C22 A31) aluminum panels 85 mm (3 3/8 in) x 170
mm (6 3/4 in) x 0.8 mm (1/32 in) thick.
6.8.1.2 Air circulating oven.
6.8.1.3 12 mm (1/2 in) wide masking tape.
6.8.1.4 Three single strength glass panels 85 mm (3 3/8 in) x 170 mm (6 3/4 in).
6.8.1.5 Three rigid plates, steel or aluminum 85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 6 mm (1/4 in) thick.
6.8.1.6 Three weights, 910 g (2 lb) each.
6.8.2 Procedure
Prepare three specimens as follows:
Place two 12 mm (1/2 in) wide strips of masking tape on the face side of the aluminum test panel surface.
Position the strips parallel to each other using the panel’s long edges as guides. These strips shall run the
AAMA 800-XX, DRAFT #2, DATED 6/3/15 Page 24
entire length of the panel. The tape in position on each edge of the face side shall be approximately 0.18
mm (0.007 in) thick.
Place an additional strip of 12 mm (1/2 in) tape on top of each applied tape. Position this tape so that it
covers the entire length of the panel. (This double thickness of tape will serve as a 0.36 mm (0.019 in)
spacer.) Apply a 3 mm (1/8 in) diameter bead of test compound approximately 12 mm (1/2 in) inside and
parallel to each side of the panel. Apply across bottom of the panel to complete the "U" shape trough.
Holding the single strength glass by its edges, carefully place it on the sealant and gently press down until
some resistance is felt. Do not attempt to force the glass to contact the tape and avoid rocking or sliding
motion while pressing.
Repeat on the remaining specimens.
Set the assemblies on a level surface and lay a rigid plate on each. Set a 910 g (2 lb) weight on the plate
in order to press and hold the assemblies for 24 hours at 25°C ± 3°C (77°F ± 5°F). At the end of 24 hours
remove the weight and plate and allow the specimens to cure undisturbed for an additional six days at
25°C ± 3°C (77°F ± 5°F). Place specimens in an air circulating oven at 82°C ± 3°C (180°F ± 5°F) for
seven days. Cool at room temperature and fill trough with tap water. Stand in vertical position for 14 days.
NOTE 6: Voids and other defects present before water exposure should be noted and disregarded in the
final evaluation.
7.0 LABORATORY TEST METHOD NOTES
7.1 SEALANT SAMPLING
The sealant to be tested shall be taken directly from a randomly selected container as commercially
supplied by the manufacturer. The container shall be full and not previously opened. The testing shall be
completed within the shelf-life recommended by the manufacturer. The sealant manufacturer's
instructions giving any options allowed in the test methods shall be obtained along with the sealant
sample.
7.2 HOW TO EVALUATE RESULTS
After testing, examine each group of specimens representing a given test. Should any one specimen be
found not to meet requirements, the given test shall be repeated.
NOTE 7: Only one repeat per test shall be permitted.
AAMA 800-XX, DRAFT #2, DATED 6/3/15 Page 25
If the sealant fails the specific retest, a new sample shall be submitted and all the requirements of the
specification shall be tested.
7.3 OPTIONAL CURE, PRE-CURE OR PRE-CONDITIONING OF TEST SPECIMENS PRIOR TO
EXPOSURE CONDITIONS
The curing conditions for a test specimen prior to test requirement exposure; i.e., 82°C ± 3°C (180°F ±
5°F) for 14 days, may require moisture and/or oxygen to facilitate a cure. Also, some compounds may
require a step-type temperature gradation for elimination of solvents prior to test exposure. The following
conditions are examples of such options.
a. 25°C ± 3°C (77°F ± 5°F) with 50% ± 5% Relative Humidity.
b. 25°C ± 3°C (77°F ± 5°F) with 95% ± 5% Relative Humidity.
c. 38°C ± 3°C (100°F ± 5°F) with 95% ± 5% Relative Humidity.
d. 25°C ± 3°C (77°F ± 5°F) (Room Temperature Average) 45% to 65% Relative Humidity.
e. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 60°C ± 3°C (140°F ±
5°F).
f. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 38°C ± 3°C (100°F ±
5°F).
Should any of the above variations thereof be specified by the compound manufacturer, a notation on the
test report shall be made indicating the conditions used. If no conditions are specified by the compound
manufacturer, the standard criteria seven days at 25°C ± 3°C (77°F ± 5°F) shall be used prior to the
elevated temperature exposure requirements in the test.
NOTE 8: A maximum of 14 days and/or 70°C (158°F) shall be permitted to be used as an optional pre-
cure.
7.4 PEEL ADHESION PREPARATION
ASTM C794 specifies a peel strip material of desized, Grade A, Airplane Cloth, 121 g/m (4.28 oz/yd),
80/84 count.
The sealant manufacturer is permitted to specify other types of strip material to insure adequate adhesion
between the strip and the sealant. Other fabrics, foils or screens are permitted to be used. The peel strip
material shall be described and noted on the test report.
AAMA 800-XX, DRAFT #2, DATED 6/3/15 Page 26
NOTE 9: The above company is listed for convenience only and the listing is not, in any way, an approval
or endorsement by AAMA.
7.5 SUBSTRATE PREPARATION
Unless cleaning instructions are given in the individual test method, clean all metal and glass test
surfaces using the procedure outlined below.
a. Always pour solvent on the rag being used. Never dip the rag in the cleaning solvent, as this
contaminates the solvent.
b. Use the "Two Rag Wipe" technique. One rag is used to wipe off the wet solvent and contaminates
from the surface. Use a second rag one time in one direction to remove any remaining solvent
and contaminants, allowing the solvent to dry on the surface without wiping with a second dry
absorbent cloth merely re-deposits the contaminants as the solvent dries.
c. Change to clean rags frequently as you see them becoming soiled. It is easy to see the soiling if
white rags are used.
d. Always use clean containers for solvent use and storage.
e. Follow solvent supplier's recommendations for solvent use and storage.
NOTE 109: Sealant manufacturer and/or sealant user should test specific sealants, substrates, primers (if
required) and cleaning procedures to ensure adequate adhesion is developed under actual conditions.
7.6 SEALANTS WITH SPACERS
Some gunnable sealants with spacer beads cannot be tested to some requirements within their
respective specifications because spacers will not allow specified test specimen configuration, or can
produce results not characteristic of the same materials without spacers. Therefore, in those cases testing
shall be done using sealants without spacers. Testing and acceptance of sealants with spacers shall be
agreed to between the sealant supplier and user. Deviations in testing due to spacers shall be noted on
the testing report.
7.7 COMPATIBILITY
This specification qualifies a sealant for use. It does not address the adhesion capability of the sealant for
a specific substrate nor the compatibility of the sealant with the materials it contacts. Adhesion and
AAMA 800-XX, DRAFT #2, DATED 6/3/15 Page 27
compatibility characteristics required for specific substrates or finishes shall be determined by the
following test methods:
NOTE 11: Several alternative test methods are available from ASTM.
A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml (20 oz), high form beaker (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Two 100 mm (4 in) pieces of plastic glazing bead and/or setting block to be evaluated.
2. Procedure
Apply a 6 mm (1/4 in) diameter linear bead of bedding material 50 mm (2 in) long to one 100 mm (4
in) piece of material to be evaluated. Immediately place the test strip (compound applied) plus one
100 mm (4 in) piece of specimen (with no compound applied) in separate beakers and cover with
watch glasses. Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a
82°C ± 3°C (180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven,
remove the material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one
hour. The material being tested shall not be evaluated until its temperature has been determined to
be 25°C ± 3°C (77°F ± 5°F). Evaluate the compatibility of the bedding compound by reporting any
differences between the plastic bead or accessory with compound applied and that without
compound. Observe the sealants and substrates for discoloration, staining, tackiness, softening or
crazing.
B. TEST METHOD B - Compatibility with Laminated Glass
1. Materials Required
a. Two 600 ml (20 oz), high form beakers (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Six pieces of laminated glass 50 mm x 50 mm (2 in x 2 in).
2. Procedure
Apply test compound approximately 6 mm (1/4 in) thick to the surface of the edge of two adjacent
sides of three laminated glass pieces being sure to cover bond line (interface of glass and
AAMA 800-XX, DRAFT #2, DATED 6/3/15 Page 28
laminate). Immediately place three specimens with test strip (compound applied) plus three
specimens (with no compound applied) in separate beakers and cover with watch glasses.
Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a 82°C ± 3°C
(180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven, remove the
material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The
material being tested shall not be evaluated until its temperature has been determined to be 25°C ±
3°C (77°F ± 5°F). When compared to the control (specimens without compound) there shall be no
differences in fogging, separation, discoloration or cracking.
7.8 RS/UV LAMP ALTERNATIVE
The following described lamp sources shall be permitted for use .
7.8.1. UV Source
The UV source shall consist of an exposure box containing UVA-340 fluorescent UV lamps positioned at
a distance of 100 mm ± 6 mm (4 in ± 1/4 in) from the surface of the test specimens.
Conventional four-lamp fluorescent fixtures shall be acceptable with the test specimens being oriented
within the confines of the reflector hood of the fixture.
NOTE 1210: UVA-340 Lamp Rotation - after 450 to 500 hours of lamp operating time, rotate lamps as
specified in ASTM G154.
7.8.2. RS lamp Source
RS type sun lamp positioned approximately 405mm (16 in) above the compound surface and able to
maintain a specimen surface temperature of 60°C ± 6°C (140°F ± 10°F). Lamps shall be replaced after
500 hours use.
NOTE 1311: Due to the discontinuation of manufacture, the RS Sunlamp specified in these test methods may not be available for use. In the event the RS Sunlamp is not available, the UV source shall be used.

7.0 LABORATORY TEST METHOD NOTES
7.1 Tape Sampling
The tape to be tested shall be taken directly from a randomly selected container as commercially supplied
by the manufacturer. The container shall be full and not previously opened. The testing shall be
completed within the shelf-life recommended by the manufacturer. The tape manufacturer's instructions
giving any options allowed in the test methods shall be obtained along with the sealant sample.
7.2 How to Evaluate Results
After testing, examine each group of specimens representing a given test. Should any one specimen be
found not to meet requirements, the given test shall be repeated.
NOTE 1: Only one repeat per test shall be permitted.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 11
If the tape fails the specific retest, a new sample shall be submitted and all the requirements of the
specification shall be tested.
7.3 Substrate Preparation
Unless cleaning instructions are given in the individual test method, clean all metal and glass test
surfaces using the procedure outlined below.
a. Always pour solvent on the rag being used. Never dip the rag in the cleaning solvent, as this
contaminates the solvent.
b. Use the "Two Rag Wipe" technique. One rag is used to wipe off the wet solvent and contaminates
from the surface. Use a second rag one time in one direction to remove any remaining solvent
and contaminants, allowing the solvent to dry on the surface without wiping with a second dry
absorbent cloth merely re-deposits the contaminants as the solvent dries.
c. Change to clean rags frequently as you see them becoming soiled. It is easy to see the soiling if
white rags are used.
d. Always use clean containers for solvent use and storage.
e. Follow solvent supplier's recommendations for solvent use and storage.
NOTE 2: Sealant manufacturer and/or sealant user should test specific sealants, substrates, primers (if
required) and cleaning procedures to ensure adequate adhesion is developed under actual conditions.
7.4 COMPATIBILITY
This specification qualifies a sealant for use. It does not address the adhesion capability of the sealant for
a specific substrate nor the compatibility of the sealant with the materials it contacts. Adhesion and
compatibility characteristics required for specific substrates or finishes shall be determined by the
following test methods:
A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml (20 oz), high form beaker (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 12
c. Two 100 mm (4 in) pieces of plastic glazing bead and/or setting block to be evaluated.
2. Procedure
Apply a 6 mm (1/4 in) wide 50 mm (2 in) long tape to one 100 mm (4 in) piece of material to be
evaluated. Immediately place the test strip (tape applied) plus one 100 mm (4 in) piece of specimen
(with no tape applied) in separate beakers and cover with watch glasses. Condition for 24 hours at
25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a 82°C ± 3°C (180°F ± 5°F) air circulating
oven for 72 hours. After 72 hours exposure in the oven, remove the material from the oven and
condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The material being tested shall not
be evaluated until its temperature has been determined to be 25°C ± 3°C (77°F ± 5°F). Evaluate
the compatibility of the tape by reporting any differences between the plastic bead or accessory
with tape applied and that without tape. Observe the tapes and substrates for discoloration,
staining, tackiness, softening or crazing.
B. TEST METHOD B - Compatibility with Laminated Glass
1. Materials Required
a. Two 600 ml (20 oz), high form beakers (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Six pieces of laminated glass 50 mm x 50 mm (2 in x 2 in).
2. Procedure
Apply test tape approximately 6 mm (1/4 in) thick to the surface of the edge of two adjacent sides of
three laminated glass pieces being sure to cover bond line (interface of glass and laminate).
Immediately place three specimens with test strip (tape applied) plus three specimens (with no tape
applied) in separate beakers and cover with watch glasses. Condition for 24 hours at 25°C ± 3°C
(77°F ± 5°F) then place beakers and strips in a 82°C ± 3°C (180°F ± 5°F) air circulating oven for 72
hours. After 72 hours exposure in the oven, remove the material from the oven and condition to
25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The material being tested shall not be
evaluated until its temperature has been determined to be 25°C ± 3°C (77°F ± 5°F). When
compared to the control (specimens without tape) there shall be no differences in fogging,
separation, discoloration or cracking.
7.5 RS/UV Lamp Alternative
The following described lamp sources shall be permitted for use.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 13
7.5.1 UV Source
The UV source shall consist of an exposure box containing UVA-340 fluorescent UV lamps positioned at
a distance of 100 mm ± 6 mm (4 in ± 1/4 in) from the surface of the test specimens.
Conventional four-lamp fluorescent fixtures shall be acceptable with the test specimens being oriented
within the confines of the reflector hood of the fixture.
NOTE 3: UVA-340 Lamp Rotation - after 450 to 500 hours of lamp operating time, rotate lamps as
specified in ASTM G154.
7.5.2 RS lamp Source
RS type sun lamp positioned approximately 405mm (16 in) above the compound surface and able to
maintain a specimen surface temperature of 60°C ± 6°C (140°F ± 10°F). Lamps shall be replaced after
500 hours use.
NOTE 64: Due to the discontinuation of manufacture, the RS Sunlamp specified in these test methods
may not be available for use. In the event the RS Sunlamp is not available, the UV source shall be used.

6.3.3.4 Sample D (three glass panels)
82°C ± 3°C (180°F ± 5°F) - 14 days
6.3.4 Test Procedures
6.3.4.1 Immediately following the specimen exposures described in Section 6.3.3, allow the specimens B
and D to be conditioned to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour or until the specimen
temperature measures 25°C ± 3°C (77°F ± 5°F). When all specimens have reached 25°C ± 3°C (77°F ±
5°F), make two cuts per panel with a sharp blade, cutting completely through to the substrate surface and
being careful not to cut the peel cloth strip. Cuts shall be exactly 25 mm (1 in) apart.
6.3.4.2 Cover the sealant with a polyethylene strip before placing in the tensile testing machine. This will
allow the material coated peel strip to be pulled parallel (or 180° to the sealant) at a rate of 50 mm (2 in)
per minute. Peel the sealant approximately 12 mm (1/2 in) and then cut sealant to the substrate to which
it is attached. (Undercut the compound to produce separation at the interface.) Peel only one-half the
length of each test panel and record the results. Immerse the half-peeled panels in tap water at 25°C ±
3°C (77°F ± 5°F) for seven days. At the end of seven days remove the panels and continue the test on
the remaining water-conditioned compound.

5°F). After exposure observe for vehicle migration from the edge of the compound.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 15
6.6 TEST METHOD FOR LOW TEMPERATURE FLEXIBILITY
6.6.1 Use ASTM C734 to prepare test specimens using three standard etched and anodized (AA M10C
22A 31) aluminum panels 85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 0.1 mm (1/32 in) thick and template
consisting of an aluminum or brass frame with inside dimensions of 130 mm (5 in) x 40 mm (1 1/2 in) x 6
mm (1/4 in) thick.
6.6.2 Allow test specimens to air dry for seven days at 25°C ± 3°C (77°F ± 5°F). Place the three panels in
air circulating oven for 14 days maintaining temperature at 82°C ± 3°C (180°F ± 5°F). Remove the panels
from oven and allow specimens time to reach ambient temperature. Place the assembly in deep freeze
and maintain a -14°C ± 1°C (7°F ± 2°F) for 24 hours along with a 25 mm (1 in) steel mandrel
approximately 200 mm (8 in) long. While still in the deep freeze, place each specimen in turn on the
mandrel with the aluminum plate next to the mandrel, and without holding the sealant bend the specimen
180° around the mandrel within one second.
6.7 TEST METHOD FOR WATER RESISTANCE
6.7.1 Materials Required
6.7.1.1 Three standard etched and anodized (AA M10 C22 A31) aluminum panels 85 mm (3 3/8 in) x 170
mm (6 3/4 in) x 0.8 mm (1/32 in) thick.
6.7.1.2 Air circulating oven.
6.7.1.3 12 mm (1/2 in) wide masking tape.
6.7.1.4 Three single strength glass panels 85 mm (3 3/8 in) x 170 mm (6 3/4 in).
6.7.1.5 Three rigid plates, steel or aluminum 85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 6 mm (1/4 in) thick.
6.7.1.6 Three weights, 910 g (2 lb) each.
6.7.2 Procedure
Prepare three specimens as follows:
Place two 12 mm (1/2 in) wide strips of masking tape on the face side of the aluminum test panel surface.
Position the strips parallel to each other using the panel’s long edges as guides. These strips shall run the
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 16
entire length of the panel. The tape in position on each edge of the face side shall be approximately 0.18
mm (0.007 in) thick.
Place an additional strip of 12 mm (1/2 in) tape on top of each applied tape. Position this tape so that it
covers the entire length of the panel. (This double thickness of tape will serve as a 0.36 mm (0.019 in)
spacer.) Apply a 3 mm (1/8 in) diameter bead of test compound approximately 12 mm (1/2 in) inside and
parallel to each side of the panel. Apply across bottom of the panel to complete the "U" shape trough.
Holding the single strength glass by its edges, carefully place it on the sealant and gently press down until
some resistance is felt. Do not attempt to force the glass to contact the tape and avoid rocking or sliding
motion while pressing.
Repeat on the remaining specimens.
Set the assemblies on a level surface and lay a rigid plate on each. Set a 910 g (2 lb) weight on the plate
in order to press and hold the assemblies for 24 hours at 25°C ± 3°C (77°F ± 5°F). At the end of 24 hours
remove the weight and plate and allow the specimens to cure undisturbed for an additional six days at
25°C ± 3°C (77°F ± 5°F). Place specimens in an air circulating oven at 82°C ± 3°C (180°F ± 5°F) for
seven days. Cool at room temperature and fill trough with tap water. Stand in vertical position for 14 days.
NOTE 2: Voids and other defects present before water exposure should be noted and disregarded in the
final evaluation.
6.8 TEST METHOD FOR RACKING
6.8.1 Materials Required
6.8.1.1 Six standard etched and anodized (AA M10 C22 A31) aluminum panels 85 mm (3 3/8 in) x 170

AAMA 800-XX, Draft #2, Dated 6/3/15 Page 17
6.8.3 Specimen Preparation
6.8.3.1 Use masking tape to assemble two panels into a "T" shaped angle fixture. Apply two 3 mm (1/8 in)
diameter beads of sealant, one each along the length of both corner joints formed where the panels meet.
Be careful to make each bead contact both panels along the entire length. Prepare a total of three
specimens. Allow the specimens to cure for seven days at 25°C ± 3°C (77°F ± 5°F).
6.8.4 Specimen Exposure
6.8.4.1 Place in an air circulating oven at 82°C ± 3°C (180°F ± 5°F) for 14 days.
6.8.5 Specimen Evaluation
6.8.5.1 Cool to ambient temperature 25°C ± 3°C (77°F ± 5°F). Flex the assemblies through a 10° arc from
center, once in both directions in less than three seconds.
NOTE 3: Assemblies from basic visual screening of narrow joint seam sealers may be used.
7.0 LABORATORY TEST METHOD NOTES
7.1 SEALANT SAMPLING The sealant to be tested shall be taken directly from a randomly selected container as commercially
supplied by the manufacturer. The container shall be full and not previously opened. The testing shall be
completed within the shelf-life recommended by the manufacturer. The sealant manufacturer's
instructions giving any options allowed in the test methods shall be obtained along with the sealant
sample.
7.2 HOW TO EVALUATE RESULTS After testing, examine each group of specimens representing a given test. Should any one specimen be
found not to meet requirements, the given test shall be repeated.
NOTE 4: Only one repeat per test shall be permitted.
If the sealant fails the specific retest, a new sample shall be submitted and all the requirements of the
specification shall be tested.
7.3 OPTIONAL CURE, PRE-CURE OR PRE-CONDITIONING OF TEST SPECIMENS PRIOR TO EXPOSURE CONDITIONS
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 18
The curing conditions for a test specimen prior to test requirement exposure; i.e.,
82°C ± 3°C (180°F ± 5°F) for 14 days, may require moisture and/or oxygen to facilitate a cure. Also, some
compounds may require a step-type temperature gradation for elimination of solvents prior to test
exposure. The following conditions are examples of such options.
a. 25°C ± 3°C (77°F ± 5°F) with 50% ± 5% Relative Humidity.
b. 25°C ± 3°C (77°F ± 5°F) with 95% ± 5% Relative Humidity.
c. 38°C ± 3°C (100°F ± 5°F) with 95% ± 5% Relative Humidity.
d. 25°C ± 3°C (77°F ± 5°F) (Room Temperature Average) 45% to 65% Relative Humidity.
e. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 60°C ± 3°C (140°F ±
5°F).
f. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 38°C ± 3°C (100°F ±
5°F).
Should any of the above variations thereof be specified by the compound manufacturer, a notation on the
test report shall be made indicating the conditions used. If no conditions are specified by the compound
manufacturer, the standard criteria seven days at 25°C ± 3°C (77°F ± 5°F) shall be used prior to the
elevated temperature exposure requirements in the test.
NOTE 5: A maximum of 14 days and/or 70°C (158°F) shall be permitted to be used as an optional pre-
cure.
7.4 PEEL ADHESION PREPARATION ASTM C794 specifies a peel strip material of desized, Grade A, Airplane Cloth, 121 g/m (4.28 oz/yd),
80/84 count.
The sealant manufacturer is permitted to specify other types of strip material to insure adequate adhesion
between the strip and the sealant. Other fabrics, foils or screens are permitted to be used. The peel strip
material shall be described and noted on the test report.
7.5 SUBSTRATE PREPARATION Unless cleaning instructions are given in the individual test method, clean all metal and glass test
surfaces using the procedure outlined below.
a. Always pour solvent on the rag being used. Never dip the rag in the cleaning solvent, as this
contaminates the solvent.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 19
b. Use the "Two Rag Wipe" technique. One rag is used to wipe off the wet solvent and contaminates
from the surface. Use a second rag one time in one direction to remove any remaining solvent
and contaminants, allowing the solvent to dry on the surface without wiping with a second dry
absorbent cloth merely re-deposits the contaminants as the solvent dries.
c. Change to clean rags frequently as you see them becoming soiled. It is easy to see the soiling if
white rags are used.
d. Always use clean containers for solvent use and storage.
e. Follow solvent supplier's recommendations for solvent use and storage.
NOTE 6: Sealant manufacturer and/or sealant user should test specific sealants, substrates, primers (if
required) and cleaning procedures to ensure adequate adhesion is developed under actual conditions.
7.6 SEALANTS WITH SPACERS
Some gunnable sealants with spacer beads cannot be tested to some requirements within their
respective specifications because spacers will not allow specified test specimen configuration, or can
produce results not characteristic of the same materials without spacers. Therefore, in those cases testing
shall be done using sealants without spacers. Testing and acceptance of sealants with spacers shall be
agreed to between the sealant supplier and user. Deviations in testing due to spacers shall be noted on
the testing report.
7.7 COMPATIBILITY
This specification qualifies a sealant for use. It does not address the adhesion capability of the sealant for
a specific substrate nor the compatibility of the sealant with the materials it contacts. Adhesion and
compatibility characteristics required for specific substrates or finishes shall be determined by the
following test methods:
A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml (20 oz), high form beaker (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Two 100 mm (4 in) pieces of plastic glazing bead and/or setting block to be evaluated.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 20
2. Procedure
Apply a 6 mm (1/4 in) diameter linear bead of bedding material 50 mm (2 in) long to one 100 mm (4
in) piece of material to be evaluated. Immediately place the test strip (compound applied) plus one
100 mm (4 in) piece of specimen (with no compound applied) in separate beakers and cover with
watch glasses. Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a
82°C ± 3°C (180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven,
remove the material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one
hour. The material being tested shall not be evaluated until its temperature has been determined to
be 25°C ± 3°C (77°F ± 5°F). Evaluate the compatibility of the bedding compound by reporting any
differences between the plastic bead or accessory with compound applied and that without
compound. Observe the sealants and substrates for discoloration, staining, tackiness, softening or
crazing.
B. TEST METHOD B - Compatibility with Laminated Glass
1. Materials Required
a. Two 600 ml (20 oz), high form beakers (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Six pieces of laminated glass 50 mm x 50 mm (2 in x 2 in).
2. Procedure
Apply test compound approximately 6 mm (1/4 in) thick to the surface of the edge of two adjacent
sides of three laminated glass pieces being sure to cover bond line (interface of glass and
laminate). Immediately place three specimens with test strip (compound applied) plus three
specimens (with no compound applied) in separate beakers and cover with watch glasses.
Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a 82°C ± 3°C
(180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven, remove the
material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The
material being tested shall not be evaluated until its temperature has been determined to be 25°C ±
3°C (77°F ± 5°F). When compared to the control (specimens without compound) there shall be no
differences in fogging, separation, discoloration or cracking.
7.8 RS/UV LAMP ALTERNATIVE
The following described lamp sources shall be permitted for use .
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 21
7.8.1. UV Source
The UV source shall consist of an exposure box containing UVA-340 fluorescent UV lamps positioned at
a distance of 100 mm ± 6 mm (4 in ± 1/4 in) from the surface of the test specimens.
Conventional four-lamp fluorescent fixtures shall be acceptable with the test specimens being oriented
within the confines of the reflector hood of the fixture.
NOTE 7: UVA-340 Lamp Rotation - after 450 to 500 hours of lamp operating time, rotate lamps as
specified in ASTM G154.
7.8.2. RS lamp Source

25°C ± 3°C (77°F ± 5°F) - 21 days
6.3.3.4 Sample D (three glass panels)
82°C ± 3°C (180°F ± 5°F) - 14 days
6.3.4 Test Procedures
6.3.4.1 Immediately following the specimen exposures described in Section 6.3.3, allow the specimens B
and D to be conditioned to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour or until the specimen
temperature measures 25°C ± 3°C (77°F ± 5°F). When all specimens have reached 25°C ± 3°C (77°F ±
5°F), make two cuts per panel with a sharp blade, cutting completely through to the substrate surface and
being careful not to cut the peel cloth strip. Cuts shall be exactly 25 mm (1 in) apart.
6.3.4.2 Cover the sealant with a polyethylene strip before placing in the tensile testing machine. This will
allow the material coated peel strip to be pulled parallel (or 180° to the sealant) at a rate of 50 mm (2 in)
per minute. Peel the sealant approximately 12 mm (1/2 in) and then cut sealant to the substrate to which
it is attached. (Undercut the compound to produce separation at the interface.) Peel only one-half the
length of each test panel and record the results. Immerse the half-peeled panels in tap water at 25°C ±
3°C (77°F ± 5°F) for seven days. At the end of seven days remove the panels and continue the test on
the remaining water-conditioned compound.

6.8.1.6 Three weights, 910 g (2 lb) each.
6.8.2 Procedure
Prepare three specimens as follows:
Place two 12 mm (1/2 in) wide strips of masking tape on the face side of the aluminum test panel surface.
Position the strips parallel to each other using the panel’s long edges as guides. These strips shall run the
entire length of the panel. The tape in position on each edge of the face side shall be approximately 0.18
mm (0.007 in) thick.
Place an additional strip of 12 mm (1/2 in) tape on top of each applied tape. Position this tape so that it
covers the entire length of the panel. (This double thickness of tape will serve as a 0.36 mm (0.019 in)
spacer.) Apply a 3 mm (1/8 in) diameter bead of test compound approximately 12 mm (1/2 in) inside and
parallel to each side of the panel. Apply across bottom of the panel to complete the "U" shape trough.
Holding the single strength glass by its edges, carefully place it on the sealant and gently press down until
some resistance is felt. Do not attempt to force the glass to contact the tape and avoid rocking or sliding
motion while pressing.
Repeat on the remaining specimens.
Set the assemblies on a level surface and lay a rigid plate on each. Set a 910 g (2 lb) weight on the plate
in order to press and hold the assemblies for 24 hours at 25°C ± 3°C (77°F ± 5°F). At the end of 24 hours
remove the weight and plate and allow the specimens to cure undisturbed for an additional six days at
25°C ± 3°C (77°F ± 5°F). Place specimens in an air circulating oven at 82°C ± 3°C (180°F ± 5°F) for
seven days. Cool at room temperature and fill trough with tap water. Stand in vertical position for 14 days.

found not to meet requirements, the given test shall be repeated.
NOTE 4: Only one repeat per test shall be permitted.
If the sealant fails the specific retest, a new sample shall be submitted and all the requirements of the
specification shall be tested.
7.3 OPTIONAL CURE, PRE-CURE OR PRE-CONDITIONING OF TEST SPECIMENS PRIOR TO
EXPOSURE CONDITIONS
The curing conditions for a test specimen prior to test requirement exposure; i.e., 82°C ± 3°C (180°F ±
5°F) for 14 days, may require moisture and/or oxygen to facilitate a cure. Also, some compounds may
require a step-type temperature gradation for elimination of solvents prior to test exposure. The following
conditions are examples of such options.
a. 25°C ± 3°C (77°F ± 5°F) with 50% ± 5% Relative Humidity.
b. 25°C ± 3°C (77°F ± 5°F) with 95% ± 5% Relative Humidity.
c. 38°C ± 3°C (100°F ± 5°F) with 95% ± 5% Relative Humidity.
d. 25°C ± 3°C (77°F ± 5°F) (Room Temperature Average) 45% to 65% Relative Humidity.
AAMA 800-XX, Draft #3, Dated 7/23/15 Page 25
e. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 60°C ± 3°C (140°F ±
5°F).
f. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 38°C ± 3°C (100°F ±
5°F).
Should any of the above variations thereof be specified by the compound manufacturer, a notation on the
test report shall be made indicating the conditions used. If no conditions are specified by the compound
manufacturer, the standard criteria seven days at 25°C ± 3°C (77°F ± 5°F) shall be used prior to the
elevated temperature exposure requirements in the test.
NOTE 5: A maximum of 14 days and/or 70°C (158°F) shall be permitted to be used as an optional pre-
cure.
7.4 SUBSTRATE PREPARATION
Unless cleaning instructions are given in the individual test method, clean all metal and glass test
surfaces using the procedure outlined below.
a. Always pour solvent on the rag being used. Never dip the rag in the cleaning solvent, as this
contaminates the solvent.
b. Use the "Two Rag Wipe" technique. One rag is used to wipe off the wet solvent and contaminates
from the surface. Use a second rag one time in one direction to remove any remaining solvent
and contaminants, allowing the solvent to dry on the surface without wiping with a second dry
absorbent cloth merely re-deposits the contaminants as the solvent dries.
c. Change to clean rags frequently as you see them becoming soiled. It is easy to see the soiling if
white rags are used.
d. Always use clean containers for solvent use and storage.
e. Follow solvent supplier's recommendations for solvent use and storage.
NOTE 6: Sealant manufacturer and/or sealant user should test specific sealants, substrates, primers (if
required) and cleaning procedures to ensure adequate adhesion is developed under actual conditions.
7.4 SEALANTS WITH SPACERS
AAMA 800-XX, Draft #3, Dated 7/23/15 Page 26
Some gunnable sealants with spacer beads cannot be tested to some requirements within their
respective specifications because spacers will not allow specified test specimen configuration, or can
produce results not characteristic of the same materials without spacers. Therefore, in those cases testing
shall be done using sealants without spacers. Testing and acceptance of sealants with spacers shall be
agreed to between the sealant supplier and user. Deviations in testing due to spacers shall be noted on
the testing report.
7.5 COMPATIBILITY
This specification qualifies a sealant for use. It does not address the adhesion capability of the sealant for
a specific substrate nor the compatibility of the sealant with the materials it contacts. Adhesion and
compatibility characteristics required for specific substrates or finishes shall be determined by the
following test methods:
A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml (20 oz), high form beaker (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Two 100 mm (4 in) pieces of plastic glazing bead and/or setting block to be evaluated.
2. Procedure
Apply a 6 mm (1/4 in) diameter linear bead of bedding material 50 mm (2 in) long to one 100 mm (4
in) piece of material to be evaluated. Immediately place the test strip (compound applied) plus one
100 mm (4 in) piece of specimen (with no compound applied) in separate beakers and cover with
watch glasses. Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a
82°C ± 3°C (180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven,
remove the material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one
hour. The material being tested shall not be evaluated until its temperature has been determined to
be 25°C ± 3°C (77°F ± 5°F). Evaluate the compatibility of the bedding compound by reporting any
differences between the plastic bead or accessory with compound applied and that without
compound. Observe the sealants and substrates for discoloration, staining, tackiness, softening or
crazing.
B. TEST METHOD B - Compatibility with Laminated Glass
1. Materials Required
AAMA 800-XX, Draft #3, Dated 7/23/15 Page 27

AAMA 800-XX, Draft #2, Dated 6/3/15 Page 5
6.3 TEST METHOD FOR LOW TEMPERATURE FLEXIBILITY
6.3.1 Use ASTM C734 to prepare test specimens using three standard etched and anodized (AA M10C
22A 31) aluminum panels 85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 0.1 mm (1/32 in) thick and template
consisting of an aluminum or brass frame with inside dimensions of 130 mm (5 in) x 40 mm (1 1/2 in) x 6
mm (1/4 in) thick.
6.3.2 Allow test specimens to air dry for seven days at 25°C ± 3°C (77°F ± 5°F). Place the three panels in
air circulating oven for 14 days maintaining temperature at 82°C ± 3°C (180°F ± 5°F). Remove the panels
from oven and allow specimens time to reach ambient temperature. Place the assembly in deep freeze
and maintain a -14°C ± 1°C (7°F ± 2°F) for 24 hours along with a 25 mm (1 in) steel mandrel
approximately 200 mm (8 in) long. While still in the deep freeze, place each specimen in turn on the
mandrel with the aluminum plate next to the mandrel, and without holding the sealant bend the specimen
180° around the mandrel within one second.
6.4 TEST METHOD FOR WATER RESISTANCE
6.4.1 Materials Required
6.4.1.1 Three standard etched and anodized (AA M10 C22 A31) aluminum panels
85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 0.8 mm (1/32 in) thick.
6.4.1.2 Air circulating oven.
6.4.1.3 12 mm (1/2 in) wide masking tape.
6.4.1.4 Three single strength glass panels 85 mm (3 3/8 in) x 170 mm (6 3/4 in).
6.4.1.5 Three rigid plates, steel or aluminum 85 mm (3 3/8 in) x 170 mm (6 3/4 in) x 6 mm (1/4 in) thick.
6.4.1.6 Three weights, 910 g (2 lb) each.
6.4.2 Procedure
Prepare three specimens as follows:
Place two 12 mm (1/2 in) wide strips of masking tape on the face side of the aluminum test panel surface.
Position the strips parallel to each other using the panel’s long edges as guides. These strips shall run the
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 6
entire length of the panel. The tape in position on each edge of the face side shall be approximately 0.18
mm (0.007 in) thick.
Place an additional strip of 12 mm (1/2 in) tape on top of each applied tape. Position this tape so that it
covers the entire length of the panel. (This double thickness of tape will serve as a 0.36 mm (0.019 in)
spacer.) Apply a 3 mm (1/8 in) diameter bead of test compound approximately 12 mm (1/2 in) inside and
parallel to each side of the panel. Apply across bottom of the panel to complete the "U" shape trough.
Holding the single strength glass by its edges, carefully place it on the sealant and gently press down until
some resistance is felt. Do not attempt to force the glass to contact the tape and avoid rocking or sliding
motion while pressing.
Repeat on the remaining specimens.
Set the assemblies on a level surface and lay a rigid plate on each. Set a 910 g (2 lb) weight on the plate
in order to press and hold the assemblies for 24 hours at 25°C ± 3°C (77°F ± 5°F). At the end of 24 hours
remove the weight and plate and allow the specimens to cure undisturbed for an additional six days at
25°C ± 3°C (77°F ± 5°F). Place specimens in an air circulating oven at 82°C ± 3°C (180°F ± 5°F) for
seven days. Cool at room temperature and fill trough with tap water. Stand in vertical position for 14 days.
NOTE 2: Voids and other defects present before water exposure should be noted and disregarded in the
final evaluation.
6.5 TEST METHOD FOR SLUMP
6.5.1 MATERIALS REQUIRED
As outlined in ASTM D2202.
6.5.2 PROCEDURE
Conduct test as outlined in ASTM D2202 except temperature shall be 25°C ± 3°C (77°F ± 5°F), and time
shall be five minutes. At the end of the five minute time interval record the distance of slump in millimeters
(tenths of an inch).
6.5.2.1 For 803.3 Type II materials only, alter the test fixture to use a rectangular slot, 3.2 mm (1/8”) x 38
mm (1½”) wide x 6.35mm (1/4”) deep (see Figures 9 and 10).

7.0 LABORATORY TEST METHOD NOTES
7.1 SEALANT SAMPLING
The sealant to be tested shall be taken directly from a randomly selected container as commercially
supplied by the manufacturer. The container shall be full and not previously opened. The testing shall be
completed within the shelf-life recommended by the manufacturer. The sealant manufacturer's
instructions giving any options allowed in the test methods shall be obtained along with the sealant
sample.
7.2 HOW TO EVALUATE RESULTS
After testing, examine each group of specimens representing a given test. Should any one specimen be
found not to meet requirements, the given test shall be repeated.
NOTE 7: Only one repeat per test shall be permitted.
If the sealant fails the specific retest, a new sample shall be submitted and all the requirements of the
specification shall be tested.
7.3 OPTIONAL CURE, PRE-CURE OR PRE-CONDITIONING OF TEST SPECIMENS PRIOR TO
EXPOSURE CONDITIONS
The curing conditions for a test specimen prior to test requirement exposure; i.e.,
82°C ± 3°C (180°F ± 5°F) for 14 days, may require moisture and/or oxygen to facilitate a cure. Also, some
compounds may require a step-type temperature gradation for elimination of solvents prior to test
exposure. The following conditions are examples of such options.
a. 25°C ± 3°C (77°F ± 5°F) with 50% ± 5% Relative Humidity.
b. 25°C ± 3°C (77°F ± 5°F) with 95% ± 5% Relative Humidity.
c. 38°C ± 3°C (100°F ± 5°F) with 95% ± 5% Relative Humidity.
d. 25°C ± 3°C (77°F ± 5°F) (Room Temperature Average) 45% to 65% Relative Humidity.
e. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 60°C ± 3°C (140°F ±
5°F).
f. 25°C ± 3°C (77°F ± 5°F) (45% to 65% Relative Humidity) 7 days + 7 days at 38°C ± 3°C (100°F ±
5°F).
Should any of the above variations thereof be specified by the compound manufacturer, a notation on the
test report shall be made indicating the conditions used. If no conditions are specified by the compound
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 9
manufacturer, the standard criteria seven days at 25°C ± 3°C (77°F ± 5°F) shall be used prior to the
elevated temperature exposure requirements in the test.
NOTE 8: A maximum of 14 days and/or 70°C (158°F) shall be permitted to be used as an optional pre-
cure.
7.4 SUBSTRATE PREPARATION
Unless cleaning instructions are given in the individual test method, clean all metal and glass test
surfaces using the procedure outlined below.
a. Always pour solvent on the rag being used. Never dip the rag in the cleaning solvent, as this
contaminates the solvent.
b. Use the "Two Rag Wipe" technique. One rag is used to wipe off the wet solvent and contaminates
from the surface. Use a second rag one time in one direction to remove any remaining solvent
and contaminants, allowing the solvent to dry on the surface without wiping with a second dry
absorbent cloth merely re-deposits the contaminants as the solvent dries.
c. Change to clean rags frequently as you see them becoming soiled. It is easy to see the soiling if
white rags are used.
d. Always use clean containers for solvent use and storage.
e. Follow solvent supplier's recommendations for solvent use and storage.
NOTE 3: Sealant manufacturer and/or sealant user should test specific sealants, substrates, primers (if
required) and cleaning procedures to ensure adequate adhesion is developed under actual conditions.
7.4 SEALANTS WITH SPACERS
Some gunnable sealants with spacer beads cannot be tested to some requirements within their
respective specifications because spacers will not allow specified test specimen configuration, or can
produce results not characteristic of the same materials without spacers. Therefore, in those cases testing
shall be done using sealants without spacers. Testing and acceptance of sealants with spacers shall be
agreed to between the sealant supplier and user. Deviations in testing due to spacers shall be noted on
the testing report.
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 10
7.5 COMPATIBILITY
This specification qualifies a sealant for use. It does not address the adhesion capability of the sealant for
a specific substrate nor the compatibility of the sealant with the materials it contacts. Adhesion and
compatibility characteristics required for specific substrates or finishes shall be determined by the
following test methods:
NOTE 11: Several alternative test methods are available from ASTM.
A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml (20 oz), high form beaker (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Two 100 mm (4 in) pieces of plastic glazing bead and/or setting block to be evaluated.
2. Procedure
Apply a 6 mm (1/4 in) diameter linear bead of bedding material 50 mm (2 in) long to one 100 mm (4
in) piece of material to be evaluated. Immediately place the test strip (compound applied) plus one
100 mm (4 in) piece of specimen (with no compound applied) in separate beakers and cover with
watch glasses. Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a
82°C ± 3°C (180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven,
remove the material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one
hour. The material being tested shall not be evaluated until its temperature has been determined to
be 25°C ± 3°C (77°F ± 5°F). Evaluate the compatibility of the bedding compound by reporting any
differences between the plastic bead or accessory with compound applied and that without
compound. Observe the sealants and substrates for discoloration, staining, tackiness, softening or
crazing.
B. TEST METHOD B - Compatibility with Laminated Glass
1. Materials Required
a. Two 600 ml (20 oz), high form beakers (no pouring lip). Two watch glass covers for same.
b. Air circulating oven.
c. Six pieces of laminated glass 50 mm x 50 mm (2 in x 2 in).
AAMA 800-XX, Draft #2, Dated 6/3/15 Page 11
2. Procedure
Apply test compound approximately 6 mm (1/4 in) thick to the surface of the edge of two adjacent
sides of three laminated glass pieces being sure to cover bond line (interface of glass and
laminate). Immediately place three specimens with test strip (compound applied) plus three
specimens (with no compound applied) in separate beakers and cover with watch glasses.
Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then place beakers and strips in a 82°C ± 3°C
(180°F ± 5°F) air circulating oven for 72 hours. After 72 hours exposure in the oven, remove the
material from the oven and condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The
material being tested shall not be evaluated until its temperature has been determined to be 25°C ±
3°C (77°F ± 5°F). When compared to the control (specimens without compound) there shall be no
differences in fogging, separation, discoloration or cracking.

FOREWARD
This document has previously been part of AAMA 800 Voluntary Specifications and Test
Methods for Sealants. These expanded cellular glazing tapes may have other
applications within the fenestration industry however this specification primarily
addresses non-structural, in-shop glazing applications.
1.0 SCOPE
To provide a minimum level of performance for expanded cellular glazing tape for use in
fenestration applications.
NOTE 1: Essential properties of both the adhesive and cellular product include:
• Ability of foam to exert a minimum sealing pressure over a range of time,
weather conditions and glass lite to frame distortions.
• Shear and perpendicular adhesion characteristics such that the cellular circular
product to glass lite bond remains uncompromised both at installation time and
through a range of weathering conditions.
1.1 Tapes shall be classified as:
Type 1
Type 2
1.1.1 Type 1 tapes are intended as primary seals where tape is used by itself to prevent
air and water leakage or in a system when the tape acts as the primary sealant.
1.1.2 Type 2 tapes are intended as secondary seals where the tape is used in
combination with a full bead of wet sealant to prevent air and water leakage. The cellular
tape in these combinations is normally used to contain the wet sealant, which is the
primary sealer.
1.3 The primary units of measure in this document are metric. The values stated in SI
units are to be regarded as the standard. The values given in parentheses are for
reference only.
2.0 PURPOSE

6.0 TESTS
6.1 TEST METHOD FOR COMPRESSION/DEFLECTION
6.1.1 MATERIALS REQUIRED
6.1.1.1 A compression machine capable of compressing the specimen at a rate of 50
mm/min (2 in/min) gently without impact. The machine is permitted to be motor or hand
driven.
6.1.1.2 The compression gauge shall be graduated to 0.025 mm (0.001 in) to measure
compression of the specimen. If the compression machine automatically compresses the
specimen 25%, no gauge is necessary.
6.1.1.3 Prepare three samples as follows:
6.1.1.3.1 Razor cut the tape test specimen to 25 mm (1 in) square, with parallel top and
bottom surfaces, perpendicular to the top surface. (Samples under 25 mm (1 in) shall be
permitted to be laid side by side to create a surface area of 625 mm2 (1 in2).) The
specimen’s thickness shall be a minimum of 6 mm (1/4 in) and is permitted to be plied to
achieve this thickness. (A razor cut square plane is specified since another form can
AAMA 800-XX, Draft #3, Dated 7/20/15 Page 4
result in uneven compression and another cutting method can result in mushrooming the
cellular tape.)
6.1.2 PROCEDURE
6.1.2.1 Calculate actual surface area of the test specimen.
6.1.2.2 Test A
Remove any release paper (adhesive should be dusted with a fine powder to reduce
tack) and compress the test specimen between parallel metal plates of the machine until
its thickness has been reduced 25% and immediately record the load in N (lbf).

NOTE 4: Release liners shall be on the top and bottom of each specimen (but not
between plies, if applicable).
6.3.2 PROCEDURE
6.3.2.1 Determine the thickness of the specimen including both release liners. Determine
the thickness of the release liner by obtaining an average measurement of a liner sample
from the same roll of tape the test specimen came from. Do not remove the release liner
from the specimen. Subtract two times the release liner thickness from the specimen
thickness and record this result as "To".
6.3.2.2 Center the specimen between the plates of the clamping device leaving release
liners on and compress it 0.25 "To" or 25% of the specimen thickness minus the release
liners.
6.3.2.3 Hold specimen in the compressed condition for 22 hours at room temperature
25°C ± 3°C (77°F ± 5°F).
6.3.2.4 Release the specimen from the clamping device and allow it to recover for 24
hours at room temperature 25°C ± 3°C (77°F ± 5°F).
6.3.2.5 Determine the final thickness of the specimen including the release liners.
Subtract two times the release liner thickness (determined above) from the final thickness
and record this result as "Tf".
6.3.3 CALCULATION
6.3.3.1 Calculate the compression set as a percentage of the original thickness as
follows:
Compression Set = T0 – Tf
X 100 T0
To = The original thickness.
Tf = Thickness at specified time after removal of the clamps.

6.4.2.2 Weigh specimen to the nearest 0.01 gram and record as "A".
6.4.2.3 Place the specimen in the center of the vacuum chamber. Place wire retaining
cage and weight (to insure cage will not move) over the specimen. Submerge specimen
in distilled water at room temperature, 25°C ± 3°C (77°F ± 5°F). The top surface of the
retaining cage shall be 50 mm (2 in) below the surface of the water. Close the vacuum
chamber and reduce the pressure above the water to 0.92 atmospheres (0.95 kg/cm2
AAMA 800-XX, Draft #3, Dated 7/20/15 Page 8
(13.5 psi) absolute). Once this pressure is achieved, maintain for three minutes. Release
the vacuum and allow the specimen to remain submerged for three minutes at room
atmospheric pressure.
6.4.2.4 Remove the chamber top, the retaining weight and the retaining cage. Transfer
the specimen (pinching as little as possible) to a lint free towel to remove surface water.
(A K-Dry towel manufactured by Kimberly-Clark is known to work well for this
application). Briefly rest each exposed surface (six total) onto a dry section of the towel
(five seconds per side). Be careful that the adhesive surface does not stick to the towel.
6.4.2.5 Weigh the specimen to the nearest 0.01 gram immediately after all surfaces are
dried. Record this measurement as "B". Calculate the percent water absorption (by
weight):
Water Absorption = (B – A)
X 100 A

AAMA 800-XX, Draft #3, Dated 7/20/15 Page 13
6.7 TEST METHOD FOR PEEL ADHESION
6.7.1 MATERIALS REQUIRED
6.7.1.1 Test machine of either the crosshead type (constant rate of extension) or dead
weight pendulum type. The machine shall have one stationary head, one moveable head,
a graduated tension weighing device with an accuracy of 45 g (0.1 lb) or less and be
capable of a head separation rate of 305 mm (12 in) per minute. The chamber shall be
capable of maintaining temperatures from 0°C to 50°C ± 3°C (32°F to 120°F ± 5°F).
6.7.1.2 Deep freeze unit capable of maintaining a temperature of 0°C ± 3°C (32°F ± 5°F).

AAMA 800-XX, Draft #3, Dated 7/20/15 Page 14
6.7.2 PROCEDURE
6.7.2.1 Scrub the application surface of all metal and glass panels with a cleaning
solvent. Repeat procedure with a rinsing solvent. Dry wipe each panel insuring no solvent
or lint remains. Do not contaminate panel surface by stacking or by touching with fingers.
6.7.2.2 Discard the first two layers of the tape from the roll. Center the tape specimen on
each panel, running parallel with the longer side. Specimen shall be flush on one end and
have an overhang of 75 mm (3 in) to 130 mm (5 in) on the other end of the panel. Avoid
trapping any air pockets under the specimen. If the adhesive surfaces on a double coated
tape differ from one side to the other, then both shall be tested and reported. In these
situations, when testing the second adhesive surface, adhere the face side of the total
length of the specimen, with liner, to a strip of the reinforcement tape. Remove the liner
and apply the specimen to the test panels as described above.
6.7.2.3 In the case of tape widths of less than 25 mm (1 in), cut additional strips from the
same roll and apply parallel and adjacent to the test specimens to provide a total width of
25 mm (1 in) for rolling purposes. Pass the PSTC roller, without application of additional
pressure over the backing of the tape lengthwise, once in each direction at the
approximate rate of 305 mm (12 in) per minute. Once rolling is complete, remove any
additional strips from the panel without disturbing the test specimen. Carefully remove the
liner, if present from all test specimens.
6.7.2.4 Apply the reinforcement tape to each specimen on the side from which the
release liner was removed. Apply the reinforcement tape starting on the end of the panel
that has the specimen flush with the end and continue across the panel. Ensure that the
test specimen is completely covered by the reinforcement tape. Fold the reinforcement
tape over the test specimen overhang approximately 50 mm (2 in) so the edges of the
reinforcement tape adheres to itself. This is to ensure that values obtained are strictly
adhesion oriented and not a combination of tensile and adhesion. Ensure that the
reinforcement tape does not adhere to or touch the panel at any time.
6.7.2.5 Condition the specimens in accordance to the following schedule:
a. Three Glass and three aluminum panels at 0°C ± 3°C (32°F ± 5°F) for 24 hours.
b. Three Glass and three aluminum panels at 50°C ± 3°C (120°F ± 5°F) for 24
hours.
AAMA 800-XX, Draft #3, Dated 7/20/15 Page 15
6.7.2.6 Remove each panel from its conditioning environment (one at a time) and test
within 60 seconds after removal. Insert the overhang of the specimen into the jaws of the
movable head. Ensure that the tray is exactly perpendicular to the pulling direction and
that the movable head is located directly over the test specimen.
6.7.2.7 Test the specimen by peeling at a rate of 305 mm (12 in) per minute. Record the
average peel adhesion value (using no less than eight data points from the specimen),
disregarding the first and last 25mm (1 in) from the specimen panel. Try to keep the
angle of separation as close to 90° as possible. If foam tear occurs, report the highest
recorded load value up to the occurrence of the tear. Record the mode of failure on the
report.
6.7.2.8 Convert the average value to N/mm (lb/in width) for each specimen and report.
Values shall be grouped according to panel type and test condition.
7.0 LABORATORY TEST METHOD NOTES
7.1 TAPE SAMPLING
The tape to be tested shall be taken directly from a randomly selected container as
commercially supplied by the manufacturer. The container shall be full and not previously
opened. The testing shall be completed within the shelf-life recommended by the
manufacturer. The tape manufacturer's instructions giving any options allowed in the test
methods shall be obtained along with the tape sample.
7.2 HOW TO EVALUATE RESULTS
After testing, examine each group of specimens representing a given test. Should any
one specimen be found not to meet requirements, the given test shall be repeated.
NOTE 6: Only one repeat per test shall be permitted.
If the tape fails the specific retest, a new sample shall be submitted and all the
requirements of the specification shall be tested.
7.3 SUBSTRATE PREPARATION
Unless cleaning instructions are given in the individual test method, clean all metal and
glass test surfaces using the procedure outlined below.
AAMA 800-XX, Draft #3, Dated 7/20/15 Page 16
a. Always pour solvent on the rag being used. Never dip the rag in the cleaning
solvent, as this contaminates the solvent.
b. Use the "Two Rag Wipe" technique. One rag is used to wipe off the wet solvent
and contaminates from the surface. Use a second rag one time in one direction
to remove any remaining solvent and contaminants, allowing the solvent to dry
on the surface without wiping with a second dry absorbent cloth merely re-
deposits the contaminants as the solvent dries.
c. Change to clean rags frequently as you see them becoming soiled. It is easy to
see the soiling if white rags are used.
d. Always use clean containers for solvent use and storage.
e. Follow solvent supplier's recommendations for solvent use and storage.
NOTE 7: Sealant manufacturer and/or sealant user should test specific sealants,
substrates, primers (if required) and cleaning procedures to ensure adequate adhesion is
developed under actual conditions.
7.4 COMPATIBILITY
This specification qualifies a tape for use. It does not address the adhesion capability of
the tape for a specific substrate nor the compatibility of the tape with the materials it
contacts. Adhesion and compatibility characteristics required for specific substrates or
finishes shall be determined by the following test methods:
A. TEST METHOD A - Compatibility with Plastic Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml (20 oz), high form beaker (no pouring lip). Two watch glass covers
for same.
b. Air circulating oven.
c. Two 100 mm (4 in) pieces of plastic glazing bead and/or setting block to be
evaluated.
2. Procedure
AAMA 800-XX, Draft #3, Dated 7/20/15 Page 17
Apply a 6 mm (1/4 in) wide 50 mm (2 in) long tape to one 100 mm (4 in) piece of
material to be evaluated. Immediately place the test strip (tape applied) plus one
100 mm (4 in) piece of specimen (with no tape applied) in separate beakers and
cover with watch glasses. Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then
place beakers and strips in a 82°C ± 3°C (180°F ± 5°F) air circulating oven for 72
hours. After 72 hours exposure in the oven, remove the material from the oven and
condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The material
being tested shall not be evaluated until its temperature has been determined to be
25°C ± 3°C (77°F ± 5°F). Evaluate the compatibility of the tape by reporting any
differences between the plastic bead or accessory with tape applied and that
without tape. Observe the tape and substrates for discoloration, staining, tackiness,
softening or crazing.
B. TEST METHOD B - Compatibility with Laminated Glass
1. Materials Required
a. Two 600 ml (20 oz), high form beakers (no pouring lip). Two watch glass covers
for same.
b. Air circulating oven.
c. Six pieces of laminated glass 50 mm x 50 mm (2 in x 2 in).
2. Procedure
Apply test tape approximately 6 mm (1/4 in) thick to the surface of the edge of two
adjacent sides of three laminated glass pieces being sure to cover bond line
(interface of glass and laminate). Immediately place three specimens with test strip
(tape applied) plus three specimens (with no tape applied) in separate beakers and
cover with watch glasses. Condition for 24 hours at 25°C ± 3°C (77°F ± 5°F) then
place beakers and strips in a 82°C ± 3°C (180°F ± 5°F) air circulating oven for 72
hours. After 72 hours exposure in the oven, remove the material from the oven and
condition to 25°C ± 3°C (77°F ± 5°F) for a minimum of one hour. The material
being tested shall not be evaluated until its temperature has been determined to be
25°C ± 3°C (77°F ± 5°F). When compared to the control (specimens without tape)
there shall be no differences in fogging, separation, discoloration or cracking.
