9、 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 committe

10、e 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 electrotechni

11、cal 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 b

12、odies 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 a

13、ny or all such patent rights. ISO 12633-1 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 1, Steel tubes. This first edition cancels and replaces ISO 630-2:2000, of which it constitutes a minor revision. In particular, better grouping of sever

14、al documents by subject area and minor editorial improvements have been carried out. In addition, reference number ISO 630-2 has been utilized for a new subject: technical delivery conditions for structural steels for general purposes. ISO 12633 consists of the following parts, under the general tit

16、n steels Part 1: Technical delivery conditions 1 Scope This part of ISO 12633 specifies the technical delivery requirements for hot-finished hollow sections of circular, square or rectangular form. It is applicable to hollow sections formed hot with or without subsequent heat treatment or formed col

17、d with subsequent heat treatment to obtain equivalent metallurgical conditions to those obtained in the hot-formed product. Fine grain steels are generally delivered in the normalized condition. The grades, chemical composition and mechanical properties for non-alloy steels and fine grain steels are

18、 given in Annexes A and B, respectively. NOTE 1 For the requirements for tolerances, dimensions and sectional properties, see ISO 12633-2. NOTE 2 For the technical delivery requirements of hot-rolled structural steels in other product forms, e.g. plates, wide strip, flats, bars and other structural

19、sections, see ISO 630-1 and ISO 630-2. NOTE 3 For cold-formed structural hollow sections, see ISO 10799-1 and ISO 10799-2. 2 Normative references The following referenced documents are indispensable for the application of this document.
