9、v 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 technical committees. Each member body interes
10、ted 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 closely with the International Electrotechnical C
11、ommission (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. Draft International Standards adopted by the tech
12、nical 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 document may be the subject of patent rights. ISO
13、shall not be held responsible for identifying any or all such patent rights. ISO 10799-1 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 1, Steel tubes. This first edition of ISO 10799-1 cancels and replaces ISO 10799:2001, of which it constit
14、utes a minor revision. In particular, better grouping of several documents by subject area and minor editorial improvements have been carried out. ISO 10799 consists of the following parts, under the general title Cold-formed welded structural hollow sections of non-alloy and fine grain steels: Part
15、 1: Technical delivery conditions Part 2: Dimensions and sectional properties INTERNATIONAL STANDARD ISO 10799-1:2011(E) ISO 2011 All rights reserved 1Cold-formed welded structural hollow sections of non-alloy and fine grain steels Part 1: Technical delivery conditions 1 Scope This part of ISO 10799
