The work of preparing International Standards is normally carried out through isO technical committees.Each member body interested ina 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 ElectrotechnicalCommission (lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordancewith the rulesgiven in theIsO/lEc Directives, Part2 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 member bodies casting a vote.
