The work of preparing International Standards is normally carried out throughIsotechnicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnical committee has been established has the right to be represented on that committee. International ISo collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnicalstandardization. International Standards aredrafted in accordancewith therulesgiven intheISo/IECDirectives, 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. Publication as an International Standard requires approval by at least 75 % of the member bodies castingavote.
