The work of preparing International Standards is normally carried out through ISO technical committees. Each membe
6、r body interested 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 Elec
7、trotechnical Commission (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 adopt
8、ed 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 to the possibility that some of the elements of this document may be the subject of paten

ISO 6362-3 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 6, Wrought aluminium and aluminium alloys. This third edition cancels and replaces the second edition (I
10、SO 6362-3:2001), which has been technically revised. ISO 6362 consists of the following parts, under the general title Wrought aluminium and aluminium alloys Extruded rods/bars, tubes and profiles: Part 1: Technical conditions for inspection and delivery Part 2: Mechanical properties Part 3: Extrude
