Each member body interested in a subject for which a technical committee has been 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 International Standards are drafted in accordance with the rules given in the ISO/IEc Directives, Part 2 adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75%of the memberbodies castinga vote.
