Price based on 7 pages 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 mental and non-governmental, 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 ISo Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 461/2 was prepared byTechnical Committee ISO/TC 20, Aircraft and space vehicles. Together with iSo 461/1, it cancels and replaces ISO Recommendation R 461-1965, of which it constitutes a technical revision.
