11、n 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 the right to be represented on that committee.
12、 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. International Standards are drafted in accordance wi
13、th the rules given in the ISO/IEC Directives, Part 3. Draft 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
14、to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

17、ontinuously hot-rolled steel sheet of higher yield strength with improved formability in the grades listed in Table 1. The steel is killed, made according to a fine grain practice and has a suitable chemical composition, which may include microalloying elements, to provide improved formability. The
18、product is intended for applications where parts are to be fabricated requiring better formability than is provided by normal high yield strength steel sheet. It is generally used in the delivered condition. Because of the combination of higher strength and improved formability, it is possible to ob
19、tain savings in mass along with better weldability. 1.2 This product is commonly produced in the range of thicknesses of 1,6 mm and over and widths of 600 mm and over, in coils and cut lengths. 1.3 Hot-rolled sheet less than 600 mm wide may be slit from wide sheet and will be considered as sheet. NO
20、TE Hot-rolled sheet up to but not including 3 mm in thickness is commonly known as sheet. Hot-rolled sheet 3 mm and over in thickness is commonly known as either “sheet” or “plate”. 1.4 This International Standard does not cover steel intended for boilers or pressure vessels, or steels designated as
21、 commercial quality or drawing qualities (covered in ISO 3573), or steels designated as weathering steels, having increased atmospheric corrosion resistance, or lower yield strength steels having less formability properties (covered in ISO 4995 and ISO 4996) compared with those included in this Inte

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. Howeve

For undated references, the latest edition of the normative document referred to applies. Members of ISO and IE
