The work of preparing International Standards is normally carried out through ISO technical committees. Eac

7、h member 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 Internation

8、al Electrotechnical 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 Standard

9、s 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 to the possibility that some of the elements of this document may be the subject o

ISO 6362-5 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 edi

17、poses of this part of ISO 6362, wrought aluminium and aluminium alloys are divided into two groups, which correspond to varying difficulty when manufacturing the products. The division into group I and group II of the most commonly used general engineering alloys is specified in Table 1. Grouping of
