本SAE标准规定了一个程序，用于近似计算SAE J728和SAE J1057中定义的开式刮碗器刮碗中所含典型材料的体积。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 typical materials contained in the bowl of open bowl scrapers ad 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.
