Gas cylinders - Gases and gas mixtures - Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets (ISO 10156:2017)
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.

Bouteilles à gaz - Gaz et mélanges de gaz - Détermination du potentiel d'inflammabilité et d'oxydation pour le choix des raccords de sortie de robinets (ISO 10156:2017)
L'ISO 10156:2017 spécifie des méthodes servant à déterminer si un gaz ou un mélange de gaz est ou non inflammable dans l'air et si un gaz ou un mélange de gaz est plus ou moins oxydant que l'air, dans les conditions atmosphériques.
L'ISO 10156:2017 est destiné à être utilisé 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.
L'ISO 10156:2017 ne traite pas de la préparation en toute sécurité de ces mélanges à une pression et à des températures autres que les conditions ambiantes.
Plinske jeklenke - Plini in zmesi plinov - Določitev stopnje vnetljivosti in oksidativnosti za izbiro izhodnega priključka ventila za jeklenko (ISO 10156:2017)
Ta dokument določa metode za ugotavljanje, ali je plin ali plinska zmes vnetljiva v zraku ali ne ter ali je plin oz. plinska zmes bolj ali manj oksidativna od zraka v atmosferskih pogojih.
Ta dokument je predviden za uporabo pri klasifikaciji plinov in plinskih zmesi, vključno z izbiro izhodnih odprtin ventilov plinskih jeklenk.
Ta dokument ne obsega varne priprave teh zmesi pod tlakom in pri temperaturah, ki niso okoljska temperatura.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
