6、ies (ISO member 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 organization
7、s, governmental 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 I
8、SO/IEC Directives, 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
9、 member bodies casting 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 6363-3 was prepared by Technical Committee ISO/TC 79, Light metals
10、 and their alloys, Subcommittee SC 6, Wrought aluminium and aluminium alloys. ISO 6363-3 cancels and replaces ISO 5193:1981 which has been technically revised. ISO 6363 consists of the following parts, under the general title Wrought aluminium and aluminium alloys Cold-drawn rods/bars, tubes and wir

13、 bars and wires Tolerances on form and dimensions (symmetric plus and minus tolerances on diameter) 1 Scope This part of ISO 6363 specifies tolerances on form and dimensions for wrought aluminium and aluminium alloy drawn round bars and wires having diameters in the range of from 1 mm to 100 mm incl
14、usive. The tolerances on diameter specified in this part of ISO 6363 are symmetric plus and minus tolerances. For wires, this part of ISO 6363 does not apply to electrical, welding and aeronautical purposes. For drawn bars, 4.1 to 4.5 apply, and only 4.1 and 4.2 apply to drawn wires. 2 Normative ref
15、erences The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 6363-1, Wrought aluminium and alumini

17、 in accordance with the plus and minus tolerance or the minus tolerance given in Table 1. The choice of tolerances depends on the agreement between the purchaser and the supplier.

The permissible circularity is included in the toleranc
20、e on diameter and shall not exceed half the tolerance on diameter specified in Table 1. 4.3 Straightness The straightness tolerances apply to bars having diameters from 10 mm up to and including 100 mm, in all tempers except tempers O and TX51 type tempers. Deviations from straightness shall be meas
21、ured with the bar placed on a horizontal plate so that its mass decreases the deviation. The permissible deviation from straightness in the total length, or in any 300 mm or longer section of the total length, shall be 2 mm per metre. 4.4 Fixed lengths Fixed lengths shall be agreed between the suppl
22、ier and purchaser. The tolerances on fixed lengths, given in Table 2, apply to diameters from 10 mm up to and including 100 mm.
