Transportable gas cylinders - Cylinder valves - Specification and type testing (ISO 10297:2006)
ISO 10297:2006 specifies valve design, production and marking requirements, and type test methods for valves intended to be fitted to gas cylinders which convey compressed, liquefied or dissolved gases.
ISO 10297:2006 does not apply to valves for cryogenic equipment, for fire extinguishers or for liquefied petroleum gas (LPG).
Additional specific requirements for valves fitted with pressure-reducing devices (see ISO 22435 and EN 738-3), residual pressure-retaining devices and non-return devices (see ISO 15996), and bursting discs and pressure-relief devices (see ISO 4126 and prEN 14513) are not covered by ISO 10297:2006.
NOTE Requirements for valves for liquefied petroleum gas (LPG) are specified in ISO 14245 and EN 13152, and in ISO 15995 and EN 13153. Requirements for valves for cryogenic vessels are specified in ISO 21011. Further specific requirements for valves for breathing apparatus are specified in EN 144-1, EN 144-2 and EN 144-3.

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 10297 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder
fittings.
This second edition cancels and replaces the first edition (ISO 10297:1999), which has been technically
revised.

ISO 10297:2006(E)
Introduction
Cylinder valves are fitted on gas cylinders used in, for example, industrial, medical and breathing applications.
Such valves have to perform safely and reliably for at least the cylinder test period, often in hazardous
situations.
Valves complying with this International Standard can be expected to perform satisfactorily under normal
services conditions.
This International Standard pays particular attention to:
⎯ suitability of materials;
⎯ dimensions of inlet connections;
⎯ dimensions of outlet connections;
⎯ safety (mechanical strength, endurance, resistance to ignition);
⎯ leakage;
⎯ cleanliness;
⎯ testing;
⎯ identification.
NOTE For satisfactory service, valves are manufactured and batch tested to ISO 14246.
