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

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 8, Equipment for gas welding, cutting and allied processes, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied
processes, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This third edition cancels and replaces the second edition (ISO 15615:2013), which has been technically
revised.
The main changes are as follows:
— the manual quick-acting shut-off valve has been removed because it is no longer state of the art;
— the remotely actuated shut-off valve has been removed because it is no longer state of the art;
— in 3.8 the definition of change-over unit has been added;
— in 5.2.6 a requirement has been added;
— in 5.3.4 the additional requirements for three-way valves have been clarified;
— in 5.3.6 specific requirements for pressure gauges have been added;
— new subclause 6.4 on external gas leakage test has been added;
— in 6.7.2 tolerances have been added;
— in 6.7.3 a minimum value for vacuum has been added;
— in 6.7.4.4 the test conditions for three-way valves have been clarified;
— in 6.8.2 other comparable test methods for leakage have been permitted;
— in 6.8.3 a minimum settling time of pressure has been added;
