The work of developing Internationail Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. Iinternationai 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 5670 was developed by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, and was circulated to the member bodies in November 1982. It has been approved by the member bodies of the following countries : Australia France South Africa, Rep. of Belgium eipu Spain Buigaria Iran Sweden Switzerland China Italy Czechoslovakia Korea, Dem.
