The work of preparing International Standards is normally carried out thro
8、ugh 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 collabor
9、ates 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 Standard
10、s. 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
11、 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 10509 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 13, Fasteners with non-metric thread.This second edition cancels and replaces the first ed
12、ition (ISO 10509:1992), which has been technically revised. In particular, Clauses 2 and 5, Tables 1 and 2, as well as Figures 1 and A.1 have been technically revised.
