The work of preparing International Standards is normally carried out through isO non-governmental, in liaison with IsO, also take part in the work. iso collaborates closely with the International Electrotechnical Commission (IEC)onall matters ofelectrotechnical standardization International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. adopted by the technical committees are circulated to the member bodies for voting.
