The work of developing Internationat Standards is carried out through ISO Technicat Committees. Every Member Body interested in a subject for which a Technical Committee has been set 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 Councit. Prior to 1972, the results of the work of the Technical Committees were published as Iso Recommendations; these documents are now in the process of being transformed into International Standards. As part of this process, Technical Committee ISO/TC 29 has reviewed ISO Recommendation R 504 and found it technicalty suitable for transformation. International Standard ISO 504 therefore repiaces ISO Recommendation R 504-1966 to which it is technicaliy identical. countries : France Australia Portugal Austria Germany Spain Belgium Hungary Sweden Brazil India Switzerland Canada Italy Turkey Chile Korea, Rep. of United Kingdom Netherlands Colombia U.S.A.
