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 member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 6483 was developed by Technical Committee ISO/TC 127, 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 Germany, F. R. Sweden Belgium Ireland Switzerland Bulgaria Italy United Kingdom Canada ueder USA. Czechoslovakia Poland USSR Egypt, Arab Rep. of Romania Finland South Africa, Rep. of No member body expressed disapproval of the document. @ International Organization for Standardization, 1980 Printed in Switzerland Copyrightlnteratioal Organizatin for Standardization No reproduction or networking permitted without license from IHS Not for Resale ISO 6483-1980 (E) INTERNATIONALSTANDARD Earth-moving machinery - Dumper bodies - Volumetric rating 1 Scope and field of application 4.3 Boundaries of the struck volume This International Standard specifies a procedure for approxi- 4.3.1 The interior surfaces of the body - bottom, sides, ejec- mating the volume of typical materials carried in dumper tion or retention device. bodies.
