10、2 BS ISO 4141-1:2005 iv Foreword ISO (the International 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

11、 a subject for which a technical committee has been established 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 Commiss

12、ion (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 main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical

13、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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall

14、not be held responsible for identifying any or all such patent rights. ISO 4141-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This second edition cancels and replaces the first edition (ISO 4141-1:1998), which has been technic

15、ally revised. ISO 4141 consists of the following parts, under the general title Road vehicles Multi-core connecting cables: Part 1: Test methods and requirements for basic performance sheathed cables Part 2: Test methods and requirements for high-performance sheathed cables Part 3: Construction, dim
