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

This document was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2,
Cylinder fittings.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
This second edition cancels and replaces the first edition (ISO 14245:2006) which has been technically
revised. The main changes compared to the previous edition are as follows:
— introduction of new definitions;
— change of informative Annex on production testing to normative Annex;
— new requirement for the valve to withstand vibration during transport and introduction of vibration
testing;
— restructure of Clause 5, valve type testing;
— removal of valve testing after ageing;
— increase of valve test pressure for leak tightness tests;
— introduction of excess flow valve testing; and
— introduction of non-return valve testing.

Introduction
This document covers the function of a LPG cylinder valve as a closure (defined by the UN Model
[15]
Regulations ).
This document has been written so that it is suitable to be referenced in the UN Model Regulations.
Cylinder valves complying with this document can be expected to perform satisfactorily under normal
service conditions.
Considering the changes described in the Foreword, when an LPG cylinder valve has been approved
according to the previous version of this document the body responsible for approving the same LPG
cylinder valve to this new edition should consider which tests need to be performed.
In this document the unit bar is used, due to its universal use in the field of technical gases. It should,
however, be 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.
