22、l rithgs reresvde Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a sub
23、ject 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 collaborates closely with the International Electrotechnical Commission (I
24、EC) 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 Standards. Draft International Standards adopted by the technical commit
25、tees 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 document may be the subject of patent rights. ISO shall not be
26、 held responsible for identifying any or all such patent rights. ISO 4762 was prepared by Technical Committee ISO/TC 2, Fasteners. This fourth edition cancels and replaces the third edition (ISO 4762:1997), which has been technically revised. ENISO4762:2004ANRETNIITOTS LANDNADRA OSI 6744002:2)E( ISO
