    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

    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
