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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

Introduction
This International Standard covers the function of a quick-release cylinder valve as a closure (defined
by the UN Model Regulations). Additional features of a quick-release cylinder valve (e.g. pressure
regulators, residual pressure-retaining devices, non-return devices, and pressure-relief devices) might
be covered by other standards and/or regulations.
This International Standard has been written to be in conformity with the UN Model Regulations. When
published, it will be submitted to the UN Subcommittee of Experts on the Transport of Dangerous Goods
with a request that it be included in the UN Model Regulations.
Where there is any conflict between this International Standard and any applicable regulation, the
regulation always takes precedence
In this International Standard, the unit bar is used due to its universal use in the field of technical gases.
However, it is noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa
5 5 2
(1 bar = 10 Pa = 10 N/m ).
Pressure values given in this International Standard are given as gauge pressure (pressure exceeding
atmospheric pressure) unless noted otherwise.

Specification and type testing
1 Scope
This International Standard in conjunction with ISO 10297:2014 and ISO 14246:2014 specifies design,
type testing, marking and manufacturing tests, and examinations requirements for quick-release
cylinder valves intended to be fitted to refillable transportable gas cylinders which convey non-toxic,
non-oxidizing, and non-corrosive compressed or liquefied gases or extinguishing agents charged with
compressed gases to be used for fire-extinguishing, explosion protection, and rescue applications.
NOTE 1 The main application of such quick-release cylinder valves is in the fire-fighting industry. However,
there are other applications such as to avalanche airbags, life raft inflation, and similar applications.
This International Standard covers the function of a quick-rel
