The work of preparing International
22、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, al
23、so 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 committee
24、s 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 possibi
25、lity 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 12209 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder fittings, in collaboration with Tec
26、hnical Committee CEN/TC 23, Transportable gas cylinders.This first edition of ISO 12209 cancels and replaces the first editions of the ISO 12209 series (ISO 12209-1:2000, ISO 12209-2:2000, ISO 12209-3:2000), which have been technically revised.The main changes are: combination of former three parts
27、of ISO 12209 into a single ISO 12209; modification of valve outlet, adaptor and o-ring dimensions; and addition of an outlet connection type test procedure in Annex A.iv ISO 2013 All rights reservedCopyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleN

29、 for gas cylinder valves for compressed breathable air gas cylinders. It states the fundamental requirements for both; the connection and its components and includes basic dimensions. Included in this International Standard are the following connections: yoke type outlet connection for SCUBA use up
30、to a maximum cylinder working pressure of 232 bar; threaded type outlet connections up to a maximum cylinder working pressure of 232 bar and 300 bar; and threaded type outlet connection for SCUBA use up to a maximum cylinder working pressure of 232 bar including adaptor for users to convert into a y
