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.
