scope:

Identifies test and calculation methods for the determination of flammability and oxidizing ability of gases and gas mixtures. The first test method determines whether or not a gas is flammable in air. The second test method determines if a gas or gas mixture has a greater or lesser oxidizing ability, than that of air. The calculation method, uses the characteristics of the pure substances, of which the mixture is composed, to determine the characteristics of the mixture. The results of the methods of determination, described in this standard, are intended to assist in the selection of safe gas cylinder valve outlet connections.
