本SAE标准提供了一种统一的方法，用于确定挖掘机、小型挖掘机和反铲上使用的铲斗（如SAE J1057中所定义）的额定承载力和冲击承载力，并配备了锄头附件。计算仅基于铲斗的内部物理尺寸，不使用可选的侧铣刀、防溢罩、齿或其他附件，也不考虑任何特定机器提供的铲斗动作。本文件不包括SAE J67中描述的电铲、蛤蜊或拖斗铲斗，也不包括SAE J742中描述的装载机铲斗。

This SAE Standard provides a uniform method for determining rated and struck capacity for buckets used on excavators, mini-excavators, and backhoes as defined in SAE J1057 and equipped with hoe attachment. Calculations are based on the inside physical dimensions of the bucket only, without use of optional side cutters, spill guards, teeth, or other accessories and without regard to bucket action provided by any specific machine. This document does not cover shovel, clam, or dragline buckets described in SAE J67 or loaders buckets described in SAE J742.
