b'1.TEST PROCEDURE The test was conducted in accordance with AS 1530.4:2014 Methods for fire tests on building materials,componentsandstructures,Part4:Fire-resistancetestsforelementsof construction, Section 4, for which the fire resistance of the specimen is the time, expressed in minutes, to failure under one or more of the following criteria. 1.1Integrity Failure Criteria Failure shall be deemed to occur upon collapse, the development of cracks or fissures, or other openings develop through which flames or hot gases can pass. Failure is defined when any of the following occurs: (a) A cotton pad in its frame applied against the surface of the test specimen over any crack, fissure or flaming under examination, until ignition of the cotton pad (defined as glowing or flaming) or for a maximum of 30 seconds. (b) Gap gauges employed, in turn, without undue force to determine when - a.a 6 mm gap gauge can be passed through the specimen so that the gap gauge projects into the furnace and can be moved a distance of 150 mm along the gap, or, b.a 25 mm gap gauge can be passed through the specimen so that the gap gauge projects into the furnace. (c)Sustained flaming on the surface of the unexposed face for 10 seconds or longer constitutes integrity failure. 1.2Insulation Failure Criteria Failure in relation to insulation shall be deemed to have occurred if: (a) the mean temperature of the relevant thermocouples attached to the unexposed face of the specimen rises by more than 140 K above the initial temperature; or, (b) the maximum temperature anywhere on the unexposed surface rises more than 180 K above the initial temperature. 2.DESCRIPTION OF TEST SPECIMEN 2.1General The test specimen consisted of a wall nominally 3,000 mm high x 3,000 mm wide, formed from three, 100 mm thick DeltaCool-MW panels. Two of the panels were full size, 3,000 mm tall by 1,200 mm wide, the width of the third panel was cut to 590 mm. The panels were installed within a concrete lined specimen holder and orientated such that the panel joints were vertical. The panels were fixed to the specimen holder on both horizontal edges and one vertical edge on both faces of the wall with 50 mm x 50 mm x 1.2 mm thick steel angle.
