If the tolerance is exceeded for any of the test speeds, the measured engine speeds shall be used.\nIntermediate test points within the control area shall be determined as follows:\n%torque = % of maximum torque;\n%speed = n − n idle n 100 % − n idle × 100 ;\nwhere: n100 % is the 100 % speed for the corresponding test cycle.\nFigure 5.1\nControl area for variable-speed engines of category NRE with maximum net power ≥ 19 kW, variable-speed engines of category IWA with maximum net power ≥ 300 kW and variable-speed engines of category NRG",
