FOREWORD

This test report details a fire resistance test conducted on a sheet and stud partition system. Thetest sponsor was British Gypsum Limited.

The test specimen was installed by British Gypsum. The construction of the specimen took placebetween the 28th May and 29th May 2002. British Gypsum Limited designed and selected thematerials comprising the test specimen.

The test date was carried out on the 30th May 2002.

This report details the method of construction, the test conditions and the results obtainedwhen the specific element of construction described herein was tested following theprocedures outlined in EN 1363-1, and where appropriate EN 1363-2. Any significant deviationwith respect to size, constructional details, loads, stresses, edge or end conditions other thanthose allowed under the field of direct application in EN 1364-1 is not covered by this report.

Because of the nature of fire resistance testing and the consequent difficulty in quantifying theuncertainty of measurement of fire resistance, it is not possible to provide a stated degree ofaccuracy of the result.

REPORT AUTHORISATION

The Building Test Centre will not discuss the content of this report without written permissionfrom the test sponsor. The Building Test Centre retains ownership of the test report contentbut authorises the test sponsor to reproduce the report as necessary in its entirety only.

TEST CONSTRUCTION

The specimen was constructed in a refractory concrete lined steel restraint frame having anopening of 5000mm high x 3000mm wide.

Gypframe 50C50 channels were fixed to the head and base of the test aperture at 600mmcentres with 60mm Hilti Hus fixings, 40mm from the exposed edge of the frame. Gypframe48S50 studs were positioned at 600mm centres between the channels and crimped to the headand base using a Gyproc crimping tool. Each 5000mm length of stud comprised of one full3000mm length plus a second length 2600mm long, overlapped by 600mm and fixed togetherusing two Gyproc Wafer head screws, two to each flange. The right hand stud viewed from theunexposed face was not fixed to the perimeter test frame, but the gap between the stud andthe lining was filled with a 50mm Rockwool Firebatt gasket. The left hand stud was fixed to thetest frame at 600mm centres with 60mm Hilti Hus fixings.

A gap of 37mm was allowed, then the above was repeated to provide a second metalframework on the unexposed side of the frame. Short sections of Gypframe fixing channel99FC90 were fixed horizontally between the two metal frameworks at 1200mm centres usingtwo 13mm Gyproc wafer head screws into each metal stud.

25mm Isowool 1200 was located within the centre of the 37mm gap.

A single horizontal layer of 19mm Gyproc Plank was fixed to both sides of the framework usingtwo 32mm Gyproc Drywall screws to each metal stud. An outer layer of 12.5mm SoundBloc wasfully fixed vertically to both sides and to all the studs and channels using 42mm Gyproc Drywallscrews at 300mm centres. The horizontal joints for the outer layers were positioned 2700mmfrom the base for both the exposed and unexposed sides of the construction. All vertical boardjoints were staggered between layers on both sides.

All board joints were taped and filled using Gyproc Paper Joint Tape and Gyproc Joint Filler asappropriate. The perimeter on the specimen on both sides was bonded with Gyproc Bondingcoat apart from the free end.

TEST MATERIALS

Gyproc SoundBloc

Nominally, 3000mm (long) x 1200mm (wide) x 12.5mm (thick), Gyproc SoundBloc boardmanufactured and supplied by British Gypsum Limited ex East Leake Works.

Measured surface density: 9.73 kg/m2.Measured thickness: 13.01 mm.Board identification numbers: 16 128 2 20:40Measured moisture content: 0.72%

Gyproc Plank

Nominally, 2400mm (long) x 600mm (wide) x 19mm (thick), Gyproc Plank manufactured andsupplied by British Gypsum Limited ex East Leake Works.

Measured surface density: 14.69 kg/m2.Measured thickness: 19.10 mm.Measured moisture content: 0.40%

The surface densities and board thickness’ were calculated using the actual weight and size of aselection of boards used in the test specimen. The moisture content of the boards weredetermined using samples dried to a constant weight in an oven at 40oC.

Isowool 1200 Insulation

Nominally 25mm thick glass mineral wool, manufactured and supplied by British Gypsum –Isover Limited.

Measured surface density: 0.45 kg/m2

Measured density: 18.19 kg/m3

Surface density calculated using the weight of one roll of 25mm Isowool 1200 and its nominalsurface area and nominal thickness.

TEST PROCEDURE

The test was conducted fully in accordance with BS EN 1364-1:1999. The specimen wassubjected to fire from one side, as specified in BS EN 1364-1:1999. As the test specimen isconsidered to be symmetrical one test is adequate to cover the fire resistance performance inboth directions.

The test procedure used was EN 1364-1 Issue 1.

The ambient temperature at the commencement of the test was 19oC.

The furnace pressure head was located at a height of 3 metres and the pressure wasmaintained at 1 ± 2 Pa positive with respect to the atmosphere, except during the first 6minutes of the test and also 17 – 21, 23 – 25, 69, 71 and 72 minutes,

The test conditions did not meet the full requirements of BS EN 1363-1:1999 as the furnacelinings and test frame stiffness did not fully comply. The test centre is of the opinion thatthese deviations from the documented method will not unduly effect the result of the test.

TEST RESULTS

The requirements of the standard were satisfied for the following periods:

Integrity:

Insulation:

111 minutes (6mm x 150mm gap gauge)

111 minutes (25mm gap gauge)

97 minutes (Roving thermocouple exceeded 180 deg C.)

The test was terminated at 111 minutes.

LIMITATIONS

The results only relate to the behaviour of the specimen of the element of construction underthe particular conditions of test; they are not intended to be the sole criteria for assessing thepotential fire performance of the element in use nor do they reflect the actual behaviour infires.

The specification and interpretation of fire test methods are the subject of ongoingdevelopment and refinement. Changes in associated legislation may also occur. For thesereasons it is recommended that the relevance of test reports over 5 years old should beconsidered by the user. The laboratory that issued the report will be able to offer, on behalf ofthe legal owner, a review of the procedures adopted for a particular test to ensure that theyare consistent with current practices, and if required may endorse the test report.
