23、w.wiso.ch ii ENISO15976:2002 iiiForeword 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 inter
24、ested 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 collaborates closely with the International Electrotechnical
25、 Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the te
26、chnical 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 International Standard may be the subject of pat
27、ent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15976 was prepared by Technical Committee ISO/TC 2, Fasteners. Annex A of this International Standard is for information only. ENISO15976:2002INTENRATIONAL TSANDADR IS:67951 O2002(E)I SO 2002 All irthgs
