Specifies a procedure for approximating the volume of typical materials contained in the hoe type buckets of excavators (not including cable excavators) based on the inside dimensions of the bucket and representative volumes on top of the bucket. Divides the complex shape of the bucket into simple geometric forms. Is intended to provide a consistent means of comparing bucket capacities, not actual capacities. Applies to buckets for hoe type excavators and excludes buckets for cable operated excavators.

This International Standard specifies a procedure for approximating the volume of typical materials contained in the hoe type buckets of excavators as defined in ISO 7135. 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.NOTE - These volumes of different bucket configurations may be calculated by the use of any combination of analytical, graphical or measuring techniques.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.This International Standard applies to buckets for hoe type excavators and excludes buckets for cable operated excavators.
