Gas cylinders - Gases and gas mixtures - Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets

ISO 10156:2017 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.ISO 10156:2017 is intended to be used for the classification of gases and gas mixtures including the selection of gas cylinder valve outlets.ISO 10156:2017 does not cover the safe preparation of these mixtures under pressure and at temperatures other than ambient.

Le présent document spécifie des méthodes servant à déterminer si un gaz ou un mélange de gaz est ou non inflammable à l'air et si un gaz ou un mélange de gaz est plus ou moins oxydant que l'air, dans les conditions atmosphériques. Il est destiné à être utilisée pour la classification des gaz et des mélanges de gaz, y compris pour le choix des raccords de sortie de robinets de bouteilles à gaz. Son principal objectif est d'éliminer les ambiguïtés soulevées par les contradictions des données bibliographiques et, surtout, de compléter les données existantes (principalement dans le cas des mélanges de gaz) . Le présent document ne traite pas de la préparation en toute sécurité de ces mélanges à une pression et à des températures autres que les conditions ambiantes.
