The work of developing International interested in a subject for which a technical committee has been authorized 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 4296/1 was developed by Technical Committee ISO/TC 65, Manganese and chromium ores, and was circulated to the member bodies in May 1983. It has been approved by the member bodies of the following countries: Austria India South Africa, Rep. of Bulgaria Italy Thailand China Japan United Kingdom Czechoslovakia Poland USSR France Romania The member body of the following country expressed disapproval of the document on technical grounds: Australia International Organization for Standardization, 1984 ? .
