The work of preparing Inter
45、national Standards is normally carried out through ISO technical committees. Each member bodyinterested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with
46、ISO, also take part in the work. ISO collaborates closelywith 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.The main task of technical co
47、mmittees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval byat least 75 % of the member bodies casting a vote. Attention is drawn to the p
