Specifies a procedure for approximating the volume in the bucket of front loading, front end loaders and excavators. Based on the inside dimensions of the bucket and representative volumes on top, dividing the complex shape of the material in the bucket into simple geometric forms. Provides a consistent means of comparing bucket capacities, not actual capacities.

This International Standard specifies a procedure for approximating the volume of typical materials contained in the bucket of front 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.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.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.
