The work
14、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-government
15、al, 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 mai
16、n 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. Att
17、ention 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 6722-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical a
18、nd electronic equipment. This fourth edition of ISO 6722-1 cancels and replaces ISO 6722:2006, which has been technically revised. ISO 6722 consists of the following parts, under the general title Road vehicles 60 V and 600 V single-core cables: Part 1: Dimensions, test methods and requirements for
19、copper conductor cables Part 2: Dimensions, test methods and requirements for aluminium conductor cables 1)1) To be published.

20、copper conductor cables WARNING The use of this International Standard may involve hazardous materials, operations, and equipment. This International Standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this Interna
21、tional Standard to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use. 1 Scope This part of ISO 6722 specifies the dimensions, test methods, and requirements for single-core 60 V cables intended for use in road vehicle applications where the
22、 nominal system voltage is (60 V d.c. or 25 V a.c.). It also specifies additional test methods and/or requirements for 600 V cables intended for use in road vehicle applications where the nominal system voltage is greater than (60 V d.c. or 25 V a.c.) to (600 V d.c. or 600 V a.c.). It also applies t
23、o individual cores in multi-core cables. This part of ISO 6722 specifies requirements for copper conductor cables. 2 Normative references The following referenced documents are indispensable for the application of this document.

Unless specified otherwise, all tests other than “In process” tests shall be cond
43、ucted at these conditions. Where no tolerance is specified, all values shall be considered to be approximate. When a.c. tests are performed, they shall be at 50 Hz or 60 Hz. Applications at higher frequencies may require additional testing. 4.6 Ovens An oven with air exchange, either natural or by p
44、ressure, should be used. The air shall enter the oven in such a way that it flows over the surface of the test pieces and exits near the top of the oven. The oven shall have not less than 8 and not more than 20 complete air changes per hour at the specified ageing temperature. Forced air circulation
45、, e.g. by a fan inside the oven may be used. However, in case of dispute, an oven without forced air circulation shall be used. 4.7 Representative conductor sizes for testing When a test is required, all combinations of conductor size, wall thickness, and insulation formulation shall meet the approp
46、riate requirements. However, if testing of representative conductor sizes is permitted (see Table 3), compliance for a cable family may be demonstrated by testing examples of large and small conductor sizes only. Permission to show compliance for a cable family by testing “representative conductor s
47、izes” shall be established by agreement between customer and supplier. 4.8 Recommended colours A list of recommended colours is shown in Table C.1. 5 Tests and requirements 5.1 Outside cable diameter 5.1.1 Purpose This test is intended to verify that the cable outside diameter is within the required
48、 tolerances to fit seal and harness dimension requirements. 5.1.2 Test Sample Prepare a test sample of 3 m in length. 5.1.3 Test Use a measuring device which shall not cause deformation. Take three sets of measurements at positions separated by 1 m and record the highest and lowest outside cable diameter at each position. BS ISO 6722-1:2011 ISO 6722-1:2011 (E) ISO 20126 5.1.4 Requirement All measurements shall be within the limits of the appropriate maximum and minimum “outside cable diameter” specified in Table 4 and Table B.2.
