18、y6 BS EN ISO 16120-3:2011ISO 16120-3:2011(E) iv ISO 2011 All rights reservedForeword 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

19、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 collaborates clo

20、sely 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 Standards. Dra

21、ft 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 docu

22、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16120-3 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 17, Steel wire rod and wire products. This second edition cancels and replaces the first editio

23、n (ISO 16120-3:2001), which has been technically revised.
