It is identical with ISO1234:1997. It supersedes BS7724:1994 which is declared obsolescent. The UK participation in its preparation wa
3、s entrusted by Technical Committee FME/9, Bolts, nuts and accessories, to Subcommittee FME/9/6, General puropse fasteners and accessories, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpret
4、ation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this Subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the
5、fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications maybe found in the BSI Standards Catalogue u
6、nder the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct

19、ndards 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 or
20、ganizations, 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. Draft International Standards adopted by the technical committees are
21、 circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO1234 was prepared by Technical Committee ISO/TC 2, Fasteners. This second edition cancels and replaces the first editi
