14、on) is a worldwide federation of national standards bodies (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 re
15、presented on that committee. International organizations, 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
16、are drafted in accordance with the rules given in the ISO/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 Internati
17、onal Standard requires approval by at least 75 % of the 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 6722-1 was
18、prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and 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

This International Standard does not purport to address all of the safe
21、ty concerns, if any, associated with its use. It is the responsibility of the user of this International 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, an
22、d requirements for single-core 60 V cables intended for use in road vehicle applications where the nominal system voltage is g100 (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 s
23、ystem voltage is greater than g33 (60 V d.c. or 25 V a.c.) to g100 (600 V d.c. or 600 V a.c.). It also applies to 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 indispensab

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
45、 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, 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
46、sizes for testing When a test is required, all combinations of conductor size, wall thickness, and insulation formulation shall meet the appropriate requirements. However, if testing of representative conductor sizes is permitted (see Table 3), compliance for a cable family may be demonstrated by te
47、sting examples of large and small conductor sizes only. Permission to show compliance for a cable family by testing “representative conductor sizes” 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 a
