本SAE推荐实施规程提供了统一的试验程序，用于测量车辆上的道路荷载力，作为车辆速度的函数，并在水动力底盘测功机上模拟80 km/h（50 mph）时的道路荷载力。有关电动测功机的应用，请参考SAE J 2263。

This SAE Recommended Practice provides uniform testing procedures for measuring the road load force on a vehicle as a function of vehicle velocity and for simulation of that road load force at 80 km/h (50 mph) on a hydrokinetic chassis dynamometer. For application to electric dynamometers, refer to SAE J 2263.
