Price based on 7 pages ermitted without license from IHS Not for Resale Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (Iso member bodies). The work of preparing Internationat Standards is normally carried out through Iso 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 organizations, govern- mental and non-governmental, in liaison with IsO, also take part in the work. Draft International Standards adopted by the technicai committees are circulated to the member bodies for approval before their acceptance as International Standards by least 75 % approval by the member bodies voting. International Standard ISO 461/2 was prepared by Technicai Committee ISO/TC 20, Aircraft and space vehicles. Together with ISO 461/1, it cancels and replaces IS0 Recommendation R 461-1965, of which it constitutes a technical revision.
