Each member body interested in a subject for representedonthatcommittee.Internationalorganizations,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. 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. International Standard IsO 9329-4 was prepared by Technical Committee steeltubesforpressurepurposes. It cancels and replaces is0 2604-2:1975, of which it constitutes a technical revision, together with parts 1, 2 and 3 of isO 9329. Iso 9329 consists of the following parts, under the general title Seamless steel tubes for pressure purposes --- Technical delivery conditions: Part 1: Unalloyed steels with specified room temperature properties Part 2: Unalloyed and alloyed steels with specified elevated tempera- tureproperties Part 3: Unalloyed and alloyed steels with specified low temperature properties Part 4: Austenitic stainless steels Annexes A and B of this part of iSO 9329 are for information only. i CoPYRIGHTInternational Organization forStandardization Licensedby
