4、ds bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organi
5、zations, govern- mental and non-governmentall in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved i
6、n accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 8479 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles. Users should note that all International Standards undergo revision from time to time and that an
