19、mber 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, governme
20、ntal 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 Direc
21、tives, 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 bodie
22、s 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 12209 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee
23、SC 2, Cylinder fittings, in collaboration with Technical 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 ma
24、in changes are: combination of former three parts 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 reservedBS EN ISO 12209:2013INTERNATIONAL STANDARD ISO 12209
25、:2013(E)Gas cylinders Outlet connections for gas cylinder valves for compressed breathable air1 ScopeThis International Standard specifies the characteristics of outlet connections for gas cylinder valves for compressed breathable air gas cylinders. It states the fundamental requirements for both; t
26、he 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 to a maximum cylinder working pressure of 232 bar; threaded type outlet connections up to a maximum cylinder working pre
27、ssure 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 yoke type outlet.Annex A gives the outlet connection type test procedures.Requirements for cylinder valves (see ISO 10297
28、) are not covered by this International Standard.Requirements for material specifications and gas/material compatibility (see ISO 11114-1 and ISO 11114-2) are not covered by this International Standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in
29、this document and are indispensable for its application. For dated references, only the edition cited applies.

33、 responsibility of the manufacturer providing the connection passes the outlet connection type test according to Annex A using an o-ring specified in Table 2.In order to ensure that the yoke does fit over the valve, minimum dimensions are given for the yoke (see Figure 3 and Table 3).No outer dimens
34、ions are given for the yoke. However, the dimensions shall be chosen such that the yoke can resist a torque applied via the screw of 20 Nm without visible permanent deformation of the thread and/or the yoke. In addition, the tests described in Annex A shall be carried out.Unless otherwise specified,
35、 the general tolerances for linear and angular dimensions shall be in accordance with class m of ISO 2768-1.Key1 yoke2 valve outlet3 o-ring4 screwFigure 1 Yoke type connection Assembly drawingFigure 2 Valve outlet dimensions2 ISO 2013 All rights reservedBS EN ISO 12209:2013ISO 12209:2013(E)Table 1 V
