SAE J1082-1989 PDF

Scope: "This procedure incorporates driving cycles that produce fuel consumption data relating to Urban. Suburban@ and Interstate driving patterns and is intended to be used to determine the relative fuel economy among vehicles and driving patterns under warmed-up conditions on test tracks@ suitable roads or chassis dynamometers.1 The urban driving cycle forms the basis of a Cold-start Test procedure described in SAE J1256. PURPOSE: This SAE Standard provides uniform testing procedures for measuring the fuel economy of light duty vehicles (motor vehicles designed primarily for transportation of persons or property and rated at 10 000 lb (4500 kg) or less) on suitable roads. (The development of the new SAE Motor Vehicle Fuel Economy Measurement Procedures - SAE 75000b.) 1Though these test cycles can be run on a chassis dynamometer@ this procedure cannot be used for compliance with mandatory fuel economy standards or fuel economy labelling forlight duty vehicles first established by the ""Energy Policy and Conservation Act@"" Public Law 94-163@ 94th Congress S. 622@ December 22@ 1975. Details of the mandatory dynamometer procedure can be obtained by contacting Environmental Protection Agency@ Fourth and M Street@ S.W.@ Washington@ DC 20460. It should be noted that correlation between chassis dynamometer and road test results has not been established."
