Earth-moving machinery — Loader and front loading excavator buckets — Volumetric ratings

Specifies a procedure for approximating the volume of typical materials contained in the bucket of front end loaders and excavators with front loading buckets. The volume ratings are based on the inside dimensions of the bucket and representative volumes on top of the bucket. 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.
