The work of developing International 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 member bodies for approval before their acceptance as International Standards by the ISo Council. International Standard ISO 5005 was developed by Technical Committee ISO/TC 127. Earth-moving machinery, and was circulated to the member bodies in June 1976. It has been approved by the member bodies of the following countries : Austria Germany South Africa, Rep. of Brazil Italy Spain Bulgaria Japan Sweden Canada Korea, Rep. of Turkey Chile United Kingdom Mexico Czechoslovakia Philippines U.S.A.
