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 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 7546 was developed by Technical Committee ISO/TC 127, Earth moving machinery, and was circulated to the member bodies in December 1981. It has been approved by the member bodies of the following countries: Australia Spain France Austria Germany, F.R. Sweden Belgium United Kingdom Italy Brazil Mexico USA Poland USSR Bulgaria Czechoslovakia Romania Egypt, Arab Rep. of South Africa, Rep. of The member body of the following country expressed disapproval of the document on technical grounds: Japan ?

The volume ratings are based on the inside dimensions of the bucket and representative volumes on top of the bucket. 1.2 The method employs the technique of dividing the complex shape of the material in the bucket into simple geometric forms to allow volume calculations of different bucket configurations. 1.3 The rating method is intended to provide a consistent means of comparing bucket capacities. It is not intended to define actual capacities that might be observed in any specific application. 2 References Iso 7131, Earth-moving machinery -- Loaders -- Terminology.1) ISO7135,Earth-movingmachinery - Excavators - Terminology.1) Slotted/grated back sheet or solid extended back sheet Back sheet Side cutter Cutting edge Side shee Tooth adapter Figure 1 --- Bucket 1) At present at the stage of draft.
