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 102971999, which has been technically revised.

Such valves have to per safely and reliably for at least the cylinder test period, often in hazardous situations. Valves complying with this International Standard can be expected to per 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.
