International organizations, govern- mental and non-governmental, in liaison with isO, also take part in the work. Iso collaborates closely with the International Electrotechnical Commission (IEC)on allmatters of electrotechnical standardization Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an Inter- naional Standard requires approval by at least 75% of the member bodies casting a vote.
