Extent: E+W+S+N.I.

The transmission used for the measurements shall be in accordance with the drawing specifications for series production transmissions and shall be new.
Modifications to the transmission to meet the testing requirements of this Annex, e.g. for the inclusion of measurement sensors or adaption of an external oil conditioning system are permitted.
The tolerance limits in this paragraph refer to measurement values without sensor uncertainty.
Total tested time per transmission individual and gear shall not exceed 5 times the actual testing time per gear (allowing re-testing of transmission if needed due to measuring or rig error).
The same transmission individual may be used for a maximum of 10 different tests, e.g. for tests of transmission torque losses for variants with and without retarder (with different temperature requirements) or with different oils. If the same transmission individual is used for tests of different oils, the recommended factory fill oil shall be tested first.
It is not permitted to run a certain test multiple times to choose a test series with the lowest results.
Upon request of the approval authority the applicant for a certificate shall specify and prove the conformity with the requirements defined in this Annex.
