21、he 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 subject for which a technical commit

22、tee 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 (IEC) on all matters of electrotech

23、nical 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 committees are circulated to the member

24、 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 held responsible for identifying

25、 any or all such patent rights. ISO 9445-1 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and alloy steels. This first edition of ISO 9445-1, together with ISO 9445-2, cancels and replaces ISO 9445:2002, the contents of which have been technically revised and

26、 separated into two parts. ISO 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 9445-1:2010INTERNATIONAL STANDARD ISO 9445-1:2009

27、(E) ISO 2009 All rights reserved 1Continuously cold-rolled stainless steel Tolerances on dimensions and form Part 1: Narrow strip and cut lengths 1 Scope This part of ISO 9445 specifies the tolerances on dimensions and form for continuously cold-rolled stainless steel narrow strip, in thicknesses of

28、 up to and including 3 mm and in rolling widths of less than 600 mm. It also applies to cut lengths taken from such strip. Narrow strip and cut lengths with widths of less than 600 mm, which are manufactured from wide strip by longitudinal slitting, are covered in ISO 9445-2. 2 Normative references

For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 6929, Steel products Definitions and classifi

30、cation 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 6929 apply. 4 Information to be supplied by the purchaser 4.1 It shall be the responsibility of the purchaser to specify all requirements that are necessary for products under this specification.

31、 Such requirements to be considered include, in the order listed, but are not limited to, the following: a) the type of delivery see 5.2 a) and 5.2 b); b) the number of this International Standard, i.e. ISO 9445-1; c) the thickness in millimetres (if necessary accurate to two decimal places) and, if

32、 required, including the relevant code letter (F or P) for a fine or precision tolerance; d) the width in millimetres and, if required, including the relevant code letter (F or P) for a fine or precision tolerance; e) the code letter R where a restricted tolerance on edge camber is required; BS EN I

38、ial requirements for the delivery conditions given in 5.3, flat products covered by this part of ISO 9445 will be delivered according to the basic specifications of this part of ISO 9445. 5.2 Type of delivery Flat products according to this part of ISO 9445 can be supplied as a) cold-rolled narrow s

39、trip (strip in rolled widths less than 600 mm); b) cut lengths from cold-rolled narrow strip cut from cold-rolled narrow strip according to item 5.2 a). 5.3 Delivery conditions of cold-rolled narrow strip and products obtained from cold-rolled narrow strip 5.3.1 Cold-rolled narrow strip and cut leng

40、ths obtained from cold-rolled narrow strip are usually supplied with cut edges. These products will have burrs caused by cutting. If there are special requirements for these edges, corresponding agreements shall be made on ordering. In this case, the strip is deemed to be cut almost free of burrs if

41、 the height of the burr is less than 10 % of the product thickness. 5.3.2 By special agreement and depending on the technical equipment of the supplier, cold-rolled narrow strip and cut lengths obtained from cold-rolled narrow strip can be delivered with special edges, e.g. deburred or rounded edges
