b'6Departure from standard The specimen was left to cure under standard laboratory atmospheric conditions as opposed to a controlled environment of the average temperature of 252 deg C and relative humidity of 455%. The specimen was conditioned for a period of 5 days prior to testing, the requirements of AS 1530.8.1-2018 stipulates a minimum 7 days. The test laboratory confirms that the minor departure in conditioning would not have significantly affected the results of this test.7Termination of the test The test was terminated at 61 minutes in accordance with the standard.8Test results 8.1Critical observations The following observations were made during the fire-resistance test: 0 minutes - Alight cribs placed in position. 25 seconds - Specimen moved in positionexposure to 29 kW/m. 1:00 minutes - Smoke is emitted from the exposed face of the wall, flaming of the sealant along the panel joint adjacent to Crib #4. 2:25 minutes - Specimen moved in positionexposure to 21 kW/m. 3:18 minutes - Crib #3 has ceased flaming. 3:25 minutes - Specimen moved in positionexposure to 14 kW/m. Seals around the exposed side of perimeter of the window are starting to melt, photograph 10. 4:25 minutes -Specimen moved in positionexposure to 11 kW/m. Crib #1 has ceased flaming. 5:10 minutes - Flaming of the sealant along the corner panel joint adjacent to Crib #1. 5:25 minutes - Specimen moved in positionexposure to 8 kW/m. 5:50 minutes - Cribs #1 and #2 have ceased flaming. 6:25 minutes - Specimen moved in positionexposure to 7 kW/m. 6:40 minutes - Smoke is observed on the unexposed side of the wall, adjacent to the corner crib #1.7:45 minutes - Flaming on sealant in the corner, adjacent to crib #1 has ceased.15 minutes - Radiant heat source shielded from the specimen. Radiometer is positioned 250-mm from the exposed face of the wall specimen in front of the inside corner, adjacent to crib #1. Cracks in the sealant along the panel joint adjacent to crib #2 have been observed, photograph 17. 17 minutes - No flaming, cracking or signs of any 3-mm through gaps. FSZ 2373| page10 of 38'
