Price based on 14 pages Copyright International Organization for Standardization tted without license from IHS 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. Standard IS0 6353/1 was developed by Technical Committee International IS/TC 47, Chemistry, and was circulated to the member bodies in May 1980. It has been approved by the member bodies of the following countries : Hungary Poland Belgium Brazil India Romania Italy China South Africa, Rep. of Czechoslovakia Korea, Rep. of Switzerland Egypt, Arab Rep. of Mexico United Kingdom Netherlands France Germany, F. R. Philippines The member bodies of the following countries expressed disapproval of the document on technical grounds : Australia USSR International Organization for Standardization, 1982 Printed in Switzerland Copyright InternationalOrganization for Standardization nitted without license from IHS Not for Resale Contents Page Scope and field of application 1 References.......... 2 3 General information.
