This document, in conjunction with ISO 10297 and ISO 14246, 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, pressure drums and tubes which convey:
— non-toxic;
— non-oxidizing;
— non-flammable; 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 avalanche airbags, life raft inflation and similar applications.
NOTE 2 Where there is no risk of ambiguity, gas cylinders, pressure drums and tubes are addressed with the
collective term “cylinders” within this document.
This document covers the function of a quick-release cylinder valve as a closure.
This document does not apply to quick-release cylinder valves for cryogenic equipment and for liquefied
petroleum gas (LPG).
This document does not apply to quick-release cylinder valves if used as the main closure of portable
fire extinguishers because portable fire extinguishers are not covered by transport regulation.
Quick-release cylinder valves of auxiliary refillable propellant gas cylinders used within or as part of
portable fire extinguishers are covered by this document, if these cylinders are transported separately,
e.g. for filling (see UN Model Regulations, Chapter 3.3, Special Provision 225, second note[1]).

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

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

Introduction

This document 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) can be covered by

other standards and/or regulations.

Quick-release cylinder valves complying with this document can be expected to perform satisfactorily

under normal service conditions.
This document pays particular attention to:
a) suitability of materials;
b) safety (mechanical strength, impact strength, endurance, leak tightness);
c) testing;
d) marking.
[1]

This document has been written so that it is suitable to be referenced in the UN Model Regulations .

In this document, 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 document are given as gauge pressure (pressure exceeding atmospheric

pressure) unless noted otherwise.

Charging of agents with a compressed gas is in some areas, e.g. fire-fighting, referred to as super-

pressurization.
