DECOMPOSITION GAS
[VDI 2263, Part 1]
Determination of the volume of decomposition gas under isoperibolic conditions:
1 g of the test substance is filled into a glass tube.
The tube it connected to a gas meter and then lowered into a heated aluminum block.
The test is carried out in two modes: at 220 °C for 8 h and at 350 °C for 5 minutes.
Flammability of the decomposition gas:
1 g of the test substance is filled into a glass tube.
The glass is lowered into an aluminum block heated to 350 °C.
The flammability of the released gases is determined by a glowing platinum wire (approx. 1000 °C) at the top of the glass tube (lowered into the tube not more than 5 mm).
It is observed, whether the gas is ignited within 5 minutes.
