  "text": "In case the losses are measured on the retarder as stand-alone unit, the results are affected by the torque losses in the bearings of the test setup. It is permitted to measure these bearing losses and subtract them from the retarder drag loss measurements.\nThe manufacturer shall guarantee that the retarder used for the measurements is in accordance with the drawing specifications for series production retarders.\nModifications to the retarder to meet the testing requirements of this Annex, e.g. for the inclusion of measurement sensors or the adaption of an external oil conditioning systems are permitted.\nBased on the family described in Appendix 6 to this Annex, measured drag losses for transmissions with retarder can be used for the same (equivalent) transmission without retarder.\nThe use of the same transmission unit for measuring the torque losses of variants with and without retarder is permitted.\nUpon request of the approval authority the applicant for a certificate shall specify and prove the conformity with the requirements defined in this Annex.",
