IIBPropylene ester, dimethyl etherButadiene, epoxy propane, ethyleneDimethyl ether, acrolein, hydrogen carbide
IICHydrogen, water gasAcetyleneCarbon disulfideEthyl nitrate

Group A includes gases like propane, while Group C covers hydrogen and acetylene.

For temperature classifications, T3 allows for temperatures up to 200°C, encompassing fuels such as gasoline, kerosene, and diesel. In contrast, T6 limits temperatures to 85°C, applicable to substances like ethyl nitrite.
