IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnicalstandardization. International Standards are drafted in accordance with therules given in the Iso/IEC Directives, Part2. The main task of technical committees is to prepare International Standards.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicationas an International Standard requires approvalbyat least 75% of thememberbodies castingavote.
