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 /withthe InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. 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 casting a vote. rights.
