AS ISO 7546:2021 pdf free download – Earth-moving machinery -Loader and front loading excavator buckets ——Volumetric ratings.
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.

5.3 Extended back sheet
The back sheet extends beyond a transverse line connecting the rear corners of the side sheets and thecutting edge does not extend beyond the transverse line connecting the front corners of the side sheets.
5.3.1 The strike plane passes through the line along the top of the extended back sheet at the rear anda line along the cutting edge at the front as shown in figure 5.
