2 Introduction

Intertek Testing Services NA (Intertek) has conducted testing for Emmedue S.P.A, on a singlePSM80 panel load-bearing wall, to evaluate its fire resistance. Testing was conducted in

accordance with the ASTM E119-07a, Fire Tests of Building Construction and Materials. Thisevaluation was completed January 29, 2008.

3 Test Samples

3.1. SAMPLE SELECTION

Samples were randomly selected on July 1, 2007 by Intertek representative Matt Lansdowne,EIT, at the Emmedue S.P.A manufacturing facility, located at Via Toniolo 39/b, Z.I. Bellocchi,61032 Fano (PU), Italy. Samples were received at Intertek San Antonio on August 28, 2007.

The subject test specimens are traceable samples selected from the manufacturer's facility.Intertek selected the specimens and has verified the composition, manufacturing techniquesand quality assurance procedures.

3.2. SAMPLE AND ASSEMBLY DESCRIPTION

Sample Designation: M210X10W4

The 10x10 load-bearing wall was constructed from three single PSME 80 panels. Two of thepanels used were 4 wide x 9-11 long with the third panel being the same length as the others

but cut down to 23 wide to fit the fame. The wall assembly was 7-1/2 thick with a 4 thickpolystyrene core (density 15kg/m) that contained electro-welded steel wire meshes made ofgalvanized drawn steel wires placed on both sides of the polystyrene sheet and connected by

joints of the same material. Mortar with a mix ratio by weight of concrete to sand to water was100 pounds of PortlandCement to 280 pounds of sand to 5.0 gallons of water mixed to besprayed and/or poured on both sides of the polystyrene sheet. The mortar was applied to anominal 1-3/4 thickness on each side of the wall with a solid cap around the perimeter of thewall that had a nominal 1-3/4 thickness.

4 Testing and Evaluation Methods

The test furnace is designed to allow the specimen to be uniformly exposed to the specifiedtime-temperature conditions. It is fitted with 6 propane/air burners positioned on the left andright side walls, designed to allow an even heat flux distribution across the face of a test speci-men while allowing no direct flame impingement. The maximum energy input into the furnace is15 MBtu/hr. The furnace operator has controls which allow the following items to be variedduring the test: the overall energy input into the furnace; the air/gas ratio to the burners; and,the input of additional air beyond that passing through the burners. The furnace opening is 14 ftwide, 12 ft tall and 4 ft deep. It may be fitted with a collar that reduces the front opening to 10 ft


4/55


x 10 ft, if desired. Furnace pressures may be maintained at any value from +0.15" W.C. to -0.15" W.C. Any full-size vertical fire test furnace will have a pressure difference between thebottom and top of approximately 0.01 in. W.C. per vertical foot after operating temperatures arereached. For this reason, the furnace is operated by controlling the pressure within the furnace(with respect to the laboratory ambient pressure) by regulating the pressure at a specifichorizontal plane in the furnace. The furnace pressure will often be adjusted so that the "neutral

pressure plane" (that where the pressure difference between the furnace interior and thelaboratory ambient is zero) is at a desired location: for instance; at the top, at a point 1/3 of theway down from the top, or at the bottom of the specimen.

The temperature within the furnace is determined to be the mathematical average ofthermocouples located symmetrically within the furnace and positioned six inches away from thevertical face of the test specimen. The materials used in the construction of thesethermocouples are those suggested in the test standard. During the performance of a fireexposure test, the furnace temperatures are recorded every six seconds and displayed for thefurnace operator to allow control along the specified temperature curve. For report presentationpurposes, the data is saved once per minute.

This photograph of the vertical furnace shows it with a concrete adapter in place which reducesits opening to 120" x 120". Without the adapter the furnace will accept test specimens 144" tall

x 168" wide. The furnace is 48" deep, with burners on the sides, so that no flame impingementon the specimen occurs.

The furnace interior temperature during a test is controlled such that the area under thetimetemperature curve is within 10% of the corresponding area under the standardtimetemperature curve for 1 hour or less tests, 7.5% for those less than 2 hours and 5% forthose tests of 2 hours or more duration.

The mortar and concrete cylinder tests were performed for the sample within 48 hours of the fullscale fire resistance test. Refer to report number 3083303SAT-008 for all the test results.Compressive Strength Tests were performed by Raba Kistner Consultants, Inc, located at12821 W. Golden Lane, San Antonio, TX 78269-0287

4.1. ASTM E119-07a Fire Tests of Building Const ruct ion and Materials

"The performance of walls, columns, floors, and other building members under fire exposureconditions is an item of major importance in securing constructions that are safe, and that arenot a menace to neighboring structures nor to the public. Recognition of this is registered in thecodes of many authorities, municipal and other. It is important to secure balance of the manyunits in a single building, and of buildings of like character and use in a community; and also topromote uniformity in requirements of various authorities throughout the country. To do this it isnecessary that the fire-resistive properties of materials and assemblies be measured andspecified according to a common standard expressed in terms that are applicable alike to awide variety of materials, situations, and conditions of exposure.

Such a standard is found in the methods that follow. They prescribe a standard exposing fire ofcontrolled extent and severity. Performance is defined as the period of resistance to standardexposure elapsing before the first critical point in behavior is observed. Results are reported inunits in which field exposures can be judged and expressed.

The methods may be cited as the "Standard Fire Tests," and the performance or exposure shallbe expressed as "2-h," "6-h," "1/2-h," etc.

When a factor of safety exceeding that inherent in the test conditions is desired, a proportionalincrease should be made in the specified time-classification period.

The ASTM E119 test procedure is identical or very similar to the following standard testmethods:

UL 263UBC 7-1

NFPA 251ANSI A2.1ULC S101

The analogous test standard in the International Organization of Standardization (ISO), ISO 834Fire-resistance Tests Elements of Building Construction, is very similar to the above U.S. testmethods. Its exposure curve, as well as the method used to measure temperatures within thefurnace result in a slightly less severe temperature exposure than the E119 test for the first two

hours. The ISO 834 test requires a slightly greater positive pressure within the furnace. Forthose reasons, the E119 test can be considered to be slightly more severe for tests of 2 hduration or less, only if the test article is not likely to be affected by a higher furnace pressure.(BS 476 Pt 20 Fire tests on building materials and structures is virtually identical to the ISO 834test method, as is the new CEN standard, EN 1363-1.)

1. Scope1.1 The test methods described in this fire-test-response standard are applicable to assemblies


6/55


of masonry units and to composite assemblies of structural materials for buildings, includingbearing and other walls and partitions, columns, girders, beams, slabs, and composite slab andbeam assemblies for floors and roofs. They are also applicable to other assemblies andstructural units that constitute permanent integral parts of a finished building.1.2 It is the intent that classifications shall register comparative performance to specific fire-testconditions during the period of exposure and shall not be construed as having determined

suitability for use under other conditions or after fire exposure.1.3This standard is used to measure and describe the response of materials, products, orassemblies to heat and flame under controlled conditions, but does not by itself incorporate allfactors required for fire hazard or fire risk assessment of the materials, products or assembliesunder actual fire conditions.1.4 These test methods prescribe a standard fire exposure for comparing the test results ofbuilding construction assemblies. The results of these tests are one factor in assessingpredicted fire performance of building construction assemblies. Application of these test resultsto predict the performance of actual building construction requires the evaluation of testconditions.1.5 The values stated in inch-pound units are to be regarded as the standard. The values givenin parentheses are for information only.

1.6This standard does not purport to address all of the safety concerns, if any, associated withits use. It is the responsibility of the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatory limitations prior to use.1.7 The text of this standard references notes and footnotes which provide explanatory material.These notes and footnotes (excluding those in tables and figures) shall not be considered asrequirements of the standard.

4. Signi ficance and Use

4.1 This test method is intended to evaluate the duration for which the types of assembliesnoted in 1.1 will contain a fire, retain their structural integrity or exhibit both propertiesdependent upon the type of assembly involved during a predetermined test exposure.

4.2 The test exposes a specimen to a standard fire controlled to achieve specified temperaturesthroughout a specified time period. When required, the fire exposure is followed by theapplication of a specified standard fire hose stream. The test provides a relative measure of thefire-test-response of comparable assemblies under these fire exposure conditions. Theexposure is not representative of all fire conditions because conditions vary with changes in theamount, nature and distribution of fire loading, ventilation, compartment size and configuration,and heat sink characteristics of the compartment. Variation from the test conditions orspecimen construction, such as size, materials, method of assembly, also affects the fire-test-response. For these reasons, evaluation of the variation is required for application toconstruction in the field.4.3 The test standard provides for the following:4.3.1 For walls, partitions and floor or roof assemblies:

4.3.1.1 Measurement of the transmission of heat.4.3.1.2 Measurement of the transmission of hot gases through the assembly, sufficient to ignitecotton waste.4.3.1.3 For load bearing elements, measurement of the load carrying ability of the test specimenduring the test exposure.4.3.2 For individual load bearing assemblies such as beams and columns:4.3.2.1 Measurement of the load carrying ability under the test exposure with some consid-eration for the end support conditions (that is, restrained or not restrained).


7/55


4.4 The test standard does not provide the following:4.4.1 Full information as to performance of assemblies constructed with components or lengthsother than those tested.4.4.2 Evaluation of the degree by which the assembly contributes to the fire hazard bygeneration of smoke, toxic gases, or other products of combustion.4.4.3 Measurement of the degree of control or limitation of the passage of smoke or products of

combustion through the assembly.

4.4.4 Simulation of the fire behavior of joints between building elements such as floor-wall orwall-wall, etc., connections.4.4.5 Measurement of flame spread over surface of tested element.4.4.6 The effect of fire endurance of conventional openings in the assembly, that is electricalreceptacle outlets, plumbing pipe, etc., unless specifically provided for in the constructiontested."

The fire exposure is controlled to conform to the standard time-temperature curve shown inFigure 1, as determined by the table below:

Temperatures of Unexposed Surfaces

Temperatures of unexposed surfaces are monitored using 24 gage, Type K thermocouples

placed under 6 in. x 6 in. x 0.4 in. thick dry, felted pads as described in the standard.Temperature readings are taken at not less than nine points on the surface, at intervals notexceeding 1.0 minute. The temperature on the unexposed surface of a test specimen duringthe test is taken to be the average value of all unexposed thermocouples.

Appl ied Load

If required, this test method may be used to expose a specimen to fire and hose stream tests


8/55


while maintaining a compressive load on the wall. Unlike a non-load bearing test (in which thespecimen is typically constructed within the bounds of a masonry/structural steel frame, and iseffectively restrained on all four perimeter sides), a load bearing test is performed by "pinching"the test wall from top to bottom, while leaving the vertical sides unrestrained. This isaccomplished at this laboratory, by the use of a load-bearing frame which has a movable bottomsection. The test wall is placed (or constructed in place) between the top and bottom beams of

the load frame, and hydraulic actuators press upwards on the bottom beam until the desiredload is applied to the wall assembly. The entire frame, while maintaining the desired load, ismoved into position in front of the vertical fire resistance furnace and the fire exposure andsubsequent hose stream tests are performed.

Fire Endurance Test

The fire exposure is continued on the specimen with its applied load if applicable, until failureoccurs, or until the specimen has withstood the test conditions for the desired fire endurancerating.

Hose Stream Test

"11.1 Where required by the conditions of acceptance, the hose stream test shall beconducted to subject the specimen described in 11.2 or 11.3 to the impact, erosion, and coolingeffects of a hose stream.11.1.1 Exemption The hose stream test shall not be required in the case of constructionshaving a resistance period, indicated in the fire endurance test, of less than 1 h.11.2 The hose stream test shall be conducted on a duplicate test specimen.11.2.1 The duplicate specimen shall be exposed to the effects of the hose stream immediatelyafter being subjected to a fire endurance test for a time period of one-half the fire enduranceclassification period determined from the fire endurance test on the initial specimen.11.2.2 The length of time that the duplicate specimen is subjected to the fire endurance testshall not exceed 1 h.11.3 Optional Program As an alternative procedure, conduct the hose stream test on the

initially tested specimen immediately following its fire endurance test.11.4 In conducting the hose stream test, direct the hose stream first at the middle and then at allparts of the exposed face of the specimen. Any changes in direction shall be made slowly.

11.5 Stream Equipment and Details - The stream shall be delivered through a 21/2-in. (64-mm) hose discharging through a National Standard Playpipe of corresponding size equipped

with a 11/8-in. (28.5-mm) discharge tip of the standard-taper smooth-bore pattern withoutshoulder at the orifice. The water pressure and duration of the application shall be asprescribed [in the table below]:

11.6 Nozzle Distance - The distance between the tip of the nozzle and the center of the

exposed surface shall be determined by the deviation from normal between the center of thenozzle axis and the center of the exposed surface of the specimen. The distance shall be 20 ft(6 m) when the axis through the center of the nozzle is normal to the center of the exposedsurface. This distance shall be decreased by an amount equal to 1 ft (305 mm) for each 10 ofdeviation from the normal."

Correction Factor

When the indicated resistance period is 1/2 h or over, determined by the average or maximumtemperature rise on the unexposed surface or within the test sample, or by failure under load,, acorrection shall be applied for variation of the furnace exposure from that prescribed, where it

will affect the classification, by multiplying the indicated period by two thirds of the difference inarea between the curve of average furnace temperature and the standard curve for the firstthree fourths of the period and dividing the product by the area between the standard curve anda base line of 68F (20C) for the same part of the indicated period, the latter area increased by3240Fmin to compensate for the thermal lag of the furnace thermocouples during the first partof the test. For a fire exposure in the test higher than standard, the indicated resistance periodshall be increased by the amount of the correction. For a fire exposure in the test lower thanstandard, the indicated resistance period shall be similarly decreased for fire exposure belowstandard. The correction is accomplished by mathematically adding the correction factor, C, tothe indicated resistance period.

The correction can be expressed by the following equation:

C =2 I(AAs)

3 (As+L)

where:

C = correction in the same units as I,I = indicated fire-resistance period,

A = area under the curve of indicated average furnace temperature for the first threefourths of the indicated period,

As = area under the standard furnace curve for the same part of the indicated period,

and

L = lag correction in the same units as A and As (54Fh or 30Ch (3240Fmin or1800Cmin))

CONDITIONS OF ACCEPTANCE

16. Condit ions of Acceptance [Load-bearing Walls]


10/55


16.1 Regard the test as successful if the following conditions are met:16.1.1 The wall or partition shall have sustained the applied load during the fire endurance testwithout passage of flame or gases hot enough to ignite cotton waste, for a period equal to thatfor which classification is desired.16.1.2 The wall or partition shall have sustained the applied load during the fire and hosestream test as specified in Section 11, without passage of flame, of gases hot enough to ignite

cotton waste, or of the hose stream. The assembly shall be considered to have failed the hosestream test if an opening develops that permits a projection of water from the stream beyond theunexposed surface during the time of the hose stream test.16.1.3 Transmission of heat through the wall or partition during the fire endurance test shall nothave been such as to raise the [average] temperature on its unexposed surface more than250F (139C) above its initial temperature.

7.4 Where the conditions of acceptance place a limitation on the rise of temperature of theunexposed surface, the temperature end point of the fire endurance period shall be determinedby the average of the measurements taken at individual points; except that if a temperature riseof 30% [325F above initial temperature] in excess of the specified limit occurs at any one ofthese points, the remainder shall be ignored and the fire endurance period judged as ended.

5 Testing and Evaluation Resul ts

5.1. RESULTS AND OBSERVATIONS

The wall was placed in the laboratorys load bearing test frame and placed in front of the testfurnace on January 29, 2008. The ambient temperature at the start of the test was 66F, with arelative humidity of 88%. At 10:10AM., the furnace was fired and the standard ASTM E119 time-temperature curve was followed for a period of 60 minutes. A hydraulic pressure equivalent to alive load of 2,846 plf was applied to the wall and maintained for the duration of the fire exposure.Throughout the fire test, the pressure differential between the inside of the furnace (measured ata point 1/3 of the way down from the top center of the wall specimen) and the laboratory

ambient air was maintained at -0.03 inches of water column, which resulted in a neutralpressure at the top of the test article. Observations made during the test are as follows:

Time (min:sec) Observation0:00 The test was started at 10:10 AM.

10:00 Spalling started to occur from the exposed side of the sample.

10:10 The skim coat on the exposed side of the sample was falling.

32:00 Cracks formed throughout the exposed side of the wall.

60:00 The test was terminated.

62:30 The hose stream test began.

63:30 The hose stream test ended.

The wall withstood the fire resistance test without passage of flame or gases hot enough toignite cotton waste, for the 60-minute test, at which time the furnace was extinguished and thehose stream test was conducted. Transmission of heat through the wall during the fireendurance test did not raise the average temperature on the unexposed surface more than250F, nor any individual temperature more than 325F.

Following the fire test, the test wall was removed from the furnace, and exposed, against theheated surface, to the impact, cooling and erosion effects of the standard hose stream test. The


11/55


nozzle pressure was 30 psi, the distance between the nozzle and the wall surface was 20 feetand the water was applied for a total period of 1 minute based on a total exposed area of 100square feet and duration of 0.6 seconds per square foot.

The wall withstood the fire and hose stream tests without passage of flame, of gases hotenough to ignite cotton waste, or of the passage of water from the hose stream. No openings

developed that permitted a projection of water from the stream beyond the unexposed surfaceduring the time of the hose stream test.

During the fire test, the wall was measured for deflection at three points along its verticalcenterline: at 30" (position #1), 60" (position #2) and 90" (position #3) from the left side of thewall. Measurements were made from a taut string to the wall surface at each location.
