to be fitted for the test

             If it is impossible or inappropriate to install the auxiliaries on the test bench, the power absorbed by them shall be determined and subtracted from the measured engine power over the whole operating area of the test cycle(s).

             6.2.                         Auxiliaries to be removed for the test

             Auxiliaries needed only for the operation of the vehicle (e.g. air compressor, air-conditioning system etc.) shall be removed for the test. Where the auxiliaries cannot be removed, the power absorbed by them may be determined and added to the measured engine power over the whole operating area of the test cycle(s).

               —    if auxiliaries needed for operating the engine are not fitted to the engine, and/or

               —    if auxiliaries not needed for operating the engine are fitted to the engine.
