This International Standard specifies methods for determining whether or not a gas or gas mixture is
flammable in air and whether a gas or gas mixture is more or less oxidizing than air under atmospheric
conditions.
This International Standard is intended to be used for the classification of gases and gas mixtures including
the selection of gas cylinder valve outlets.
This International Standard does not cover the safe preparation of these mixtures under pressure and at
temperatures other than ambient.
