The work of preparing International Standards is normally carried out through Iso which a technical committee has been established has the right to be represented on that committee. Internationat_ organizations, govern- mentai and non-governmental, in liaison with so, also take part in the work. Iso collaborates ciosely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Interna- tional Standard requires approval by at least 75 % of the member bodies casting a vote.
