Pricebasedon3pages Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards bodies (iSo member bodies). The work of developing International Standards is carried out through ISo technical committees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, governmental 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. International Standard ISO 6035 was developed by Technical Committee ISO/TC 36, Cinematography, and was circulated to the member bodies in June 1980. It has been approved by the member bodies of the following countries : Australia France Spain Austria Germany, F. R. Sweden Belgium Ireland Switzerland Canada Italy United Kingdom China Japan USA Czechoslovakia Poland USSR Denmark Romania Egypt, Arab Rep. of South Africa, Rep. of No member body expressed disapproval of the document. ?
