Price based on 7 pages 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 memher hodies for approval before their acceptance as International Standards by the iso Council. International Standard ISO 4948/2 was developed by Technical Committee ISO/TC 17, Steel, and was circulated to the member bodies in June 1980. It has been approved by the member bodies of the following countries : Hungary Australia Poland Austria India Romania Belgium Iran South Africa, Rep. of Bulgaria Ireland Spain Canlada Italy Sweden Chile Japan Turkey China Korea, Dem. P. Rep. of United Kingdom Czechoslovakia Korea, Rep. of USA Egypt, Arab Rcp. of Mexico USSR Finland Netherlands Venezuela France New Zealand Germany, F.R.
