Price based on 6 pages Copyright Intermational Organization for Standardization d without license from IHS Not for Resale Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards bodies (iSO member bodies). The work of preparing International Standards is normally carried out through Iso technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental 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. They are approved in accordance with ISO procedures requiring at International Standard ISO 2179 was prepared by Technical Committee ISO/TC 107, Metallic and other non-organic coatings. This second edition cancels and replaces the first edition (ISO 2179-1972), of which it constitutes a technical revision. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other international Standard implies its latest edition, unless otherwise stated.
