The work of developing Inter- national Standards is carried out through IsO technical committees. Every member body interested in a subject for which a technical committee has been set up 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 5442 was developed by Technical Committee ISO/TC 47, Chemistry, and was circulated to the member bodies in July 1976. It has been approved by the member bodies of the following countries : Israel South Africa, Rep. of Belgium Brazil Italy Spain Switzerland Chile Korea, Rep. of Czechoslovakia Mexico Thailand Netherlands France Turkey Germany, F.R. Philippines United Kingdom Poland Hungary Yugoslavia India Romania No member body expressed disapproval of the document. This International Standard has aliso been approved by the International Union of Pure and Applied Chemistry (IUPAC) ?
