12、l Organization for Standardization) 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 es

13、tablished has the right to be represented 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 standardi

14、zation.International Standards 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 votin

15、g. Publication as an International 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.

It is the responsibility of the user of this International Standard to establish appropriate safety practices and determine the applicability of regulat

19、ory limitations prior to use.1 ScopeThis International Standard specifies test methods and requirements for basic- and high-performance round, single- or multi-core sheathed cables intended for use in road vehicle applications where the nominal system voltage is (60 V d.c. or 25 V a.c.). It also spe

20、cifies additional test methods and/or requirements for 600 V cables intended for use in road vehicle applications where the nominal system voltage is (60 V d.c. or 25 V a.c.) and (600 V d.c. or 600 V a.c.).2 Normative referencesThe following referenced documents are indispensable for the application
