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.

This second edition cancels and replaces the first edition (ISO 15995:2006) 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.
