Gases and gas mixtures - Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets (ISO 10156:2010)
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.
Gase und Gasgemische - Bestimmung der Brennbarkeid und des Oxidationsvermögens zur Auswahl von Ventilausgängen (ISO 10156:2010)
Diese Internationale Norm beinhaltet Verfahren zur Bestimmung darüber, ob ein Gas oder Gasgemisch
entzündbar in Luft ist oder nicht und ob ein Gas oder Gasgemisch stärker oder weniger oxidierend als Luft
unter atmosphärischen Bedingungen ist.
Es ist beabsichtigt, diese Internationale Norm zur Einstufung von Gasen und Gasgemischen einschließlich der
Auswahl von Gasflaschenventilausgängen zu nutzen.
Diese Internationale Norm erfasst nicht die sichere Herstellung dieser Gasgemische unter Druck und unter
anderen Temperaturen als Umgebungstemperaturen.
Gaz et mélanges de gaz - Détermination du potentiel d'inflammabilité et d'oxydation pour le choix des raccords de sortie de robinets (ISO 10156:2010)
L'ISO 10156:2010 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.
Elle est destinée 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.
Elle ne traite pas de la préparation en toute sécurité de ces mélanges à une pression et à des températures autres que les conditions ambiantes.
Plini in zmesi plinov - Določitev stopnje gorljivosti in oksidativnosti za izbiro izhodnega priključka ventila na jeklenki (ISO 10156:2010)
Ta mednarodni standard opredeljuje metode za določevanje ali je ali ni plin ali zmes plina gorljiva na zraku in ali je plin ali zmes plina bolj oksidativna kot zrak v atmosferskih pogojih. Ta mednarodni standard je namenjen temu, da se uporablja za klasifikacijo plinov in zmesi plinov, vključno z izbiro izhodnega priključka ventila na jeklenki. Ta mednarodni standard ne zajema varne priprave teh zmesi pod tlakom in pri temperaturi, ki nista okoljska.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10156 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder
fittings.
This third edition of ISO 10156 cancels and replaces ISO 10156:1996 and ISO 10156-2:2005.
It gives updated data for flammability and oxidizing ability.

Introduction
[1]
ISO 5145 and other related standards establish practical criteria for the determination of outlet connections
of cylinder valves. These criteria are based on certain physical and chemical properties of the gases. In
particular, the flammability in air and the oxidizing ability are considered.
One of the potential complications that prompted the development of this International Standard is that whilst
there are abundant data in the literature relating
