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.

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/

This document was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2,
Cylinder fittings, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 23, Transportable gas cylinders, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 15245-1:2001), which has been technically
revised. It also incorporates the Amendment ISO 15245-1:2001/Amd.1:2013.
The main changes compared to the previous edition are as follows:
— modification of Figure 2;
— addition of subclause 4.5;
— minor editorial changes throughout the document to fully align with ISO/IEC Directives Part 2.

Introduction
Cylinders intended to contain compressed, liquefied or dissolved gas under pressure are fitted with
accessories (valves, straight or angle fittings) to allow release of and refilling with gas. In this document,
the term “valve” applies to such accessories.
The connection between cylinder and valve is obtained by the assembly of two parallel threads with
the same nominal pitch and thread profile – an external one on the valve stem and an internal one in
the cylinder neck – and an O-ring seal.
