22、or 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 subject for which a technical committee has been established has th

23、e 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 (IEC) on all matters of electrotechnical standardization. Internat

24、ional 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 committees are circulated to the member bodies for voting. Publication

25、 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 held responsible for identifying any or all such patent rights.

26、 ISO 9445-2 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and alloy steels. This first edition of ISO 9445-2, together with ISO 9445-1, cancels and replaces ISO 9445:2002, the contents of which have been technically revised and separated into two parts. ISO

27、9445 consists of the following parts, under the general title Continuously cold-rolled stainless steel Tolerances on dimensions and form: Part 1: Narrow strip and cut lengths Part 2: Wide strip and plate/sheet BS EN ISO 9445-2:2010INTERNATIONAL STANDARD ISO 9445-2:2009(E) ISO 2009 All rights reserve

28、d 1Continuously cold-rolled stainless steel Tolerances on dimensions and form Part 2: Wide strip and plate/sheet 1 Scope This part of ISO 9445 specifies the tolerances on dimensions and form for continuously cold-rolled stainless steel wide strip and plate/sheet, in thicknesses from 0,30 mm to 8,0 m

29、m and in rolling widths from 600 mm to 2 100 mm. It also applies to slit cold-rolled wide strip in widths less than 600 mm manufactured from wide strip by longitudinal slitting and to cut lengths manufactured from such strip. 2 Normative references The following referenced documents are indispensabl
