3、s). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and
4、 non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bod
5、ies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 7398 was prepared by Technical Committee ISO/TC 22, Road vehicles. This second edition cancels and replaces the first edition (IS0 7398:1984),

It applies to flashers intended for use on motorcyles, as defined In IS0 3833, with 6 V or 12 V electrical systems. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this Internatlonal
11、Standard. At the time of publi- cation, the editions indicated were valid. All stan- dards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the standards in- dicated below,
