The work of preparing International Standards is normally carried out through ISO tech

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
13、 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 International Standard requires approval by at least 75 %
