Auxiliaries and equipment to be removed Certain auxiliaries whose definition is linked with the operation of the machine and which may be mounted on the engine shall be removed for the test. The following non-exhaustive list is given as a sample: (a) Air compressor for brakes (b) Power steering compressor (c) Suspension compressor (d) Air-conditioning system Where auxiliaries cannot be removed, the power they absorb in the unloaded condition may be determined and added to the measured engine power (see note h of Table 1). If this value is greater than 3 per cent of the maximum power at the test speed it may be verified by the test authority.
