1.1 AS ISO 7546 specifics a procedure for approxiniating the volume of typical materials contained in the bucket affront end loaders and excavators with front loading bucket. 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 matertal 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 deline actual capacities that might be observed in any specific application.
