Sets out test methods for measuring fuel consumption of motor vehicles under controlled conditions simulating city and highway driving. Although definitive specifications for some fuels (e.g. unleaded petrol, LP gas and diesel) have been included, the Standard applies to the determination of fuel consumption of motor vehicles, having internal combustion engines, that are fuelled with any appropriate fuel.

This standard sets out test methods for measuring fuel consumption of motor vehicles under controlled conditions simulating city and highway driving. Since a comparable degree of accuracy may be obtained, measurement of the fuel consumed is made either by analysis of the exhaust gases or by direct measurement of the volume, or mass, of fuel consumed.
