The range of test conditions on the dynamometer shall be sufficient to determine the primary operating characteristics corresponding to the full range of vehicle operations.The characteristics to be determined are:aTorque ratio versus speed ratio and output speed.bInput speed versus speed ratio and output speed.cEfficiency versus speed ratio and output speed.dCapacity factor versus speed ratio and output speed.eInput torque versus input speed.NOTE: For more information about these characteristics and the design of hydrodynamic drives, see \"Design Practices--Passenger Car Automatic Transmissions,\" SAE Advances in Engineering, Vol. 5.
