The work
6、 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 and non-governmen
7、tal, 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 Directives, Part 2. The ma
8、in 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 casting a vote. At
9、tention 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.

13、 and hexagonal 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 square and hexagonal bars and wires with widths across flats up to and including 100 mm. For wires, this part o
14、f ISO 6363 does not apply to electrical, welding and aeronautical purposes. For drawn bars, 4.1 to 4.5 apply, and only 4.1 applies to drawn wires. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition
15、cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Form tolerances are measured by placing the bar on a horizontal plate under its own mass, as shown in Figures 2 and 3. 4.5.2 Straightness tolerances
23、The maximum allowable straightness tolerance, h 1,for the total length l 1 , shall be 2 mm per 1 000 mm of length (see Figure 2).
