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 and non-governmental, in liaison with Iso, also take part in the work. Draft International Standards adopted bythetechnical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO6485was developed byTechnical CommitteeISO/TC127, Earth moving machinery, and was circulated to the member bodies in August 1979. It has been approved by the member bodies of the following countries : Australia France Spain Austria Italy Sweden Beigium Japan United Kingdom Bulgaria Libyan Arab Jamahiriya USA Czechoslovakia Poland USSR Egypt, Arab Rep. of Romania Finland South Africa, Rep. of Nomemberbodyexpresseddisapprovalofthedocument.
