This procedure covers measurement of vehicle road load on a dry, straight, level road at speeds less than 113 km/h (70 mi/h).

Purpose

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 mi/h) on a hydrokinetic chassis dynamometer. For application to electric dynamometers, refer to SAE J2263.
