International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

    18、atters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are cir
