10、 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 repre
11、sented 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. Draft International Standar
12、ds 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 StandardISO7588-2 was prepared by Technical Committee ISO/TC22, Road vehicles, Subcommi
13、tteeSC3, Electrical and electronic equipment. ISO7588 consists of the following parts, under the general title Road vehicles Electrical/electronic switching devices: Part 1: Relays and flashers; Part 2: Electronic devices; Part 3: Microrelays. Annex A and Annex B of this part ofISO7588 are for infor
14、mation only.

15、part ofISO7588 specifies dimensional characteristics of electronic devices intended for road vehicles. Annex A gives additional information on the dimensions of socket apertures and Annex B gives recommended terminal identification. 2 Normatives references The following standards contain provisions
16、which, through reference in this text, constitute provisions of this part ofISO7588. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part ofISO7588 are encouraged to investigate the possibility of applying
17、the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
