10、zation) 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 b

11、e 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 standardization. Draft International

12、Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO7588-1 was prepared by Technical Committee ISO/TC22, Road vehicles, S

13、ubcommittee SC3, Electrical and electronic equipment. This first edition of ISO7588-1 cancels and replaces ISO7588:1983, which has been technically revised. ISO 7588 consists of the following parts, under the general title Road vehicles Electrical/electronic switching devices: Part 1: Relays and fla

14、shers; Part 2: Electronic devices; Part 3: Microrelays. Annex Aand Annex B of this part of ISO7588 are for information only.

Annex A gives additional information

16、 on the dimensions of 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 ISO7
