6、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 committee has been established has the right to be represented on that committee. International organizations, governmental
7、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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directive
8、s, 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 bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies c
9、asting 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 any or all such patent rights. ISO 6363-4 was prepared by Technical Committee ISO/TC 79, Light metals and their alloy
10、s, Subcommittee SC 6, Wrought aluminium and aluminium alloys. This second edition cancels and replaces the first edition (ISO 6363-4:1991), which has been technically revised. ISO 6363 consists of the following parts, under the general title Wrought aluminium and aluminium alloys Cold-drawn rods/bar

13、t 4: Drawn rectangular bars and wires Tolerances on form and dimensions 1 Scope This part of ISO 6363 specifies the tolerances on form and dimensions of wrought aluminium and aluminium alloy drawn rectangular bars and wires with thicknesses ranging from 2 mm up to and including 60 mm and widths up t
14、o and including 200 mm. For wires, this part of ISO 6363 does not apply to electrical, welding and aeronautical purposes. For drawn bars, 5.1 to 5.4 apply, and only 5.1 applies to drawn wires. 2 Normative references The following referenced documents are indispensable for the application of this doc
15、ument. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

17、nufacturing the products. The division into group I and group II of the most commonly used general engineering alloys is specified in Table 1. The division into group I and group II of the most commonly used general engineering alloys is specified in Table 1. Grouping of other alloys is subject to a
