International Standards are drafted in accordance with the rules given in the ISO/lEC Directives,Part 2. The main task of technical committees is to prepare International Standards.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 least75%ofthe memberbodies casting a vote.
