This SAE Standard applies to dumper bodies as defined in SAE J1016 and dumper trailers as defined in SAE J734. It is similar to ISO 6483.

See the following sections of SAE J1057 for machine identification: See SAE J1016 for additional component nomenclature.

This SAE Standard specifies a procedure for approximating the volume of typical materials contained in the bowl of Open Bowl scrapers as defined in SAE J728 and SAE J1057. The volumes are based on the inside dimensions of the bowl and representative volumes on top of the bowl. This rating method is intended to provide a consistent means of comparing capacities; it is not intended to define actual capacities that might be observed in any specific application.

This standard identifies earthmoving machines which are intended for use on unimproved surfaces. The machines are used for moving earth and other materials on projects such as road building, dams, open pit excavation, trenching, and buildings. Excluded are machines intended for use on improved surfaces such as "in-plant" material handling, highways, water, air transport, and for agricultural purposes. The parts of the standard are: loaders, dumpers, tractor-scrapers, graders, tractors, excavators, and backhoe loaders. Additional parts will be developed if and when requested.
