1. Flame duration time: to a flame at 1000+ 100℃, a belt test specimen of full thickness shall be inserted against flame, as per drawing, and after keeping it burn for 1 minute, take the burner off, then measure the flame duration time of the test specimen.

2. Flame reapperance test: after 60+ 10 seconds from when the burner is removed for the flame duration test, air is blown at a speed of 1.5m/sec. with an air blower from the direction shown in the figure to the left. And the test specimen shall be visually inspected for reappearance of flame.
