SO Price based on 3 pages Copyright International Organization for Standardization Not for Resale Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards institutes (IsO member bodies). 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 756/1 was developed by Technical Committee iSO/TC 47, Chemistry, and was circulated to the member bodies in October 1980. It has been approved by the member bodies of the following countries : Egypt, Arab Rep. of Korea, Rep. of Australia Netherlands Austria France Belgium Germany, F. R. Poland Hungary Brazil Romania Bulgaria India Switzerland Ireland United Kingdom China Czechoslovakia Italy USSR The member body of the following country expressed disapproval of the document on technical grounds : South Africa, Rep. of International Standards ISO 756/1, IS0 756/2 and ISO 756/3 cancel and replace ISO Recommendation R 756-1968 of which they constitute a technical revision.
