ISO 10156:2010
Gases and gas mixtures — Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets
ISO 10156:2010 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.
It is intended to be used for the classification of gases and gas mixtures including the selection of gas cylinder valve outlets.
It does not cover the safe preparation of these mixtures under pressure and at temperatures other than ambient.
