Scope

This procedure covers measurement of vehicle road load on a straight@ level road at speeds less than 113 km/h (70 mph). 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 mph) on a chassis dynamometer.
