Division 4.4 Measurement and calculation of running resistance using the torque meter method

Original text. Later amendments are not shown.

As an alternative to the coastdown methods, the torque meter method may also be used in which the running resistance is determined by measuring wheel torque on the driven wheels at the reference speed points for time periods of at least 5 seconds.
