10、ies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and
11、 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (1 EC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bo
12、dies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
