Common use of Measurement Criteria Clause in Contracts

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. The corrected values measured for the engine sampled shall not differ by more than the values indicated in the table below and ±10 per cent for the specific fuel consumption. Engine type Reference power (torque) [%] Other measurement points on the curve [%] Tolerance for engine speed [%] General ±5 ±10 ±5 Petrol fuelled spark ignited engines with governor ±8 ±12 ±8 Petrol fuelled spark ignited engines without governor ±8 ±20 ±8
