Measurement Criteria. 4.1. Net power and specific fuel consumption of internal combustion engine Measurements shall be taken at a sufficient number of engine speeds to define correctly the power, torque and specific fuel consumption curves between the lowest and the highest engine speeds recommended by the manufacturer as defined in paragraphs 2.9. and 2.11. of this Regulation. The values measured by the technical service for the engine sampled shall not differ by more than ± 5 per cent for the net power (torque), and ± 10 per cent for the specific fuel consumption, at all measurement points on the curve with a tolerance of ± 5 per cent for engine speed.
