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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 5171 was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 8, Equipment for gas welding, cutting and allied processes.
This third edition cancels and replaces the second edition (ISO 5171:1995), which has been technically
revised.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 8 via your national standards body. A complete listing of these bodies can be
found at http://www.iso.org/.

compressed gas systems at pressures up to 30 MPa (300 bar) in welding, cutting and allied processes. It also
covers use for dissolved acetylene and for liquefied gases under pressure.
It does not cover gauges for acetylene in acetylene-manufacturing plants.
