23、Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been establ

24、ished hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.

25、International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.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

28、vIntroductionCylinders intended to contain compressed, liquefied or dissolved gas under pressure are fitted with accessories(valves, straight or angle fittings) to allow release of and refilling with gas. Hereinafter, the term “valve” applies tosuch accessories.The connection between cylinder and va
