Critical observations 
The following observations were made during the fire-resistance test: 
0 minutes -  Alight cribs placed in position. 
29 seconds -  Specimen moved into position – exposure to 29 kW/m². 
2:36 minutes -  Specimen moved into position – exposure to 21 kW/m². 
3:29 minutes -  Specimen moved into position – exposure to 14 kW/m².  
Crib #1 (inside the gutter) has ceased flaming. 
4:18 minutes - Crib #4 has ceased flaming. 
4:29 minutes - Specimen moved into position – exposure to 11 kW/m². 
5:29 minutes - Specimen moved into position – exposure to 8 kW/m². 
6:47 minutes -  Crib #3 has ceased flaming. Smoke is observed inside the roof cavity. 
7 minutes -  Smoke is observed at the top of the roof. 
10 minutes -  Smoke has ceased being emitted from the specimen. 
15 minutes -  Radiant heat source shielded from the specimen. No flaming, cracking or signs of 
any 3-mm through gaps. 
16 minutes - Radiometer is positioned 250-mm from the centre of the exposed face of the roof 
specimen. 
20 minutes - Pilot flame was applied over the exposed face of the specimen – no ignition was 
noted at this time. 
33 minutes - Pilot flame was applied over the exposed face of the specimen – no ignition was 
noted at this time. 
60 minutes -  Test terminated. 
 Post test, the back face of the roof assembly was removed to check for any gaps 
around the vents from inside the roof cavity. No through gaps >3-mm were found  
in the specimen.

period. 
Figure 2 shows the curve of received radiation versus time at 250-mm from the fire exposed face 
of the specimen.
