根据SAE J728和SAE J1057中的定义，本SAE标准规定了一个程序，用于近似计算提升式铲运机斗中典型物料的体积。体积基于碗的内部尺寸和碗顶部的代表性体积。该评级方法旨在提供一致的能力比较方法；其目的不是定义在任何特定应用中可能观察到的实际容量。

This SAE Standard specifies a procedure for approximating the volume of a typical material carried in the bowl of an elevating scraper as defined in SAE J728 and SAE J1057. The volumes are based on the inside dimensions of the bowl and a representative volume 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.
