3、 the UK national standard. It supersedes BS AU 201-1:1985 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee AUE/16, Electrical and electronic equipment, which has the responsibility to: aid enquirers to understand the text; present to the responsible in
4、ternational/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to
5、its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI
6、Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary o

12、ord 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 a subject for which a techni
13、cal 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 Commission (IEC) on all matters of e
14、lectrotechnical standardization. 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. International Standard ISO 7588-1 was pr
15、epared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This first edition of ISO 7588-1 cancels and replaces ISO 7588:1983, which has been technically revised. ISO 7588 consists of the following parts, under the general title Road vehicles Ele
16、ctrical/electronic switching devices: Part 1: Relays and flashers; Part 2: Electronic devices; Part 3: Microrelays. Annex A and Annex B of this part of ISO 7588 are for information only.

Annex A gives additional information on the dimensions of
19、 socket apertures and Annex B gives additional information on the different terminal functional allocation of flasher unit systems. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 7588. At the time of
20、publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 7588 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
