The work of preparing International Standards is normally carried out through Iso technical committees.

Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the iso Council. They are approved in accordance with IsO procedures requiring at least 75 % approval by the member bodies voting.
