The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which atechnical committee has been established ha
22、s the right to be represented onthatcommittee. 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 ofelectrotechnical standardization. Interna
23、tional Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part3. 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 least75% of the member
24、bodies casting a vote.
