The work of preparing International Standards is normally carried out through ISO technical committees.Eachmemberbodyinterestedin a subjectforwhichatechnical S B committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International opy Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 8 DraftInternationalStandardsadoptedbythetechnicalcommitteesarecirculated to the member bodies for voting. Publication as an International Standard requires , Uncontrol approval by at least 75 % of the member bodies casting a vote.
