Annex G - Heat Exposure Test
This Annex measures the temperature resistance of the vent. Traditionally this is the last test, and there is not much left at the end!
The test procedure is to raise the temperature inside the burn chamber to 350º over a period of 5 minutes with panel closed and then open it under power and leave for 25 minutes during at 350º. All the time the vent must not show any mechanical failure.
