  "text": "The Annex to Delegated Regulation (EU) 2017/655 is corrected as follows:\n(1) point 5.1 is replaced by the following:\n‘5.1.\nThe ECU shall provide data stream information to the measurement instruments or data logger of the Portable Emissions Measurement System (PEMS) in accordance with the requirements set out in Appendix 7.’;\n(2) points 6.1 to 6.4 are replaced by the following:\n6.1. ‘In-service monitoring tests shall be conducted using PEMS in accordance with Appendix 1.\n6.2. Manufacturers shall comply with the test procedure set out in Appendix 2 with regard to the in-service monitoring of engines installed on non-road mobile machinery using a PEMS.\n6.3. Manufacturers shall follow the procedures set out in Appendix 3 for the pre-processing of the data resulting of the in-service monitoring of engines installed on non-road mobile machinery using a PEMS.\n6.4. Manufacturers shall follow the procedures set out in Appendix 4 for the determination of valid events during an in-service monitoring test of engines installed on non-road mobile machinery using a PEMS.’;\n(3) point 8 is replaced by the following:\n‘8.\nCalculations\nManufacturers shall follow the procedures set out in Appendix 5 for the gaseous pollutant emissions calculations for the in-service monitoring of engines installed on non-road mobile machinery using a PEMS.’;\n(4) in point 10.1, the first sentence is replaced by the following:\n‘Manufacturers shall draft a test report of the in-service monitoring of engines installed on non-road mobile machinery using a PEMS for each engine tested.’;\n(5) Appendix 5 is corrected as follows:\n(a) point 2.2.1 is replaced by the following:\n‘2.2.1.\nCalculations of the brake specific gaseous pollutant emissions\nThe brake-specific gaseous pollutant emissions e gas (g/kWh) shall be calculated for each averaging window and each gaseous pollutant in the following way:\ne gas = m i W t 2, i − W t 1, i Where:\nmi is the mass emission of the gaseous pollutant during the ith averaging window, g/averaging window,\nW(t 2, i ) – W(t 1, i ) is the engine work during the ith averaging window, kWh.’;\n(b) point 2.2.3 is replaced by the following:\n‘2.2.3.\nCalculations of the conformity factors\nThe conformity factors shall be calculated for each individual valid averaging window and each individual gaseous pollutant in the following way:\nCF = e gas L Where:\negas is the brake-specific emission of the gaseous pollutant, g/kWh;\nL is the applicable limit, g/kWh.’;\n(c) in point 2.3, in the legend for the first equation, the indents relating to m CO 2 t j,i and m CO 2, ref are replaced by the following:\n‘ m CO 2 t j,i is the CO2 mass measured between the test start and time tj,i , g;\nm CO 2, ref is the CO2 mass determined for the NRTC, g;’;\n(d) in point 2.3.1, in the legend for the equation, the indent relating to P max is replaced by the following:\n‘ P max is the maximum net power, as defined in Article 3(28) of Regulation (EU) 2016/1628, kW.’;\n(e) point 2.3.2 is replaced by the following:\n‘2.3.2.\nCalculations of the conformity factors\nThe conformity factors shall be calculated for each individual averaging window and each individual pollutant in the following way:\nCF = CF I CF C With\nCF I = m i m CO 2 t 2, i − m CO 2 t 1, i (in service ratio) and\nCF C = m L m CO 2, ref (certification ratio)\nWhere:\nmi is the mass emission of the gaseous pollutant during the ith averaging window, g/averaging window,\nm CO 2 t 2, i − m CO 2 t 1, i is the CO2 mass during the ith averaging window, g;\nm CO 2, ref is the engine CO2 mass determined for the NRTC, g,\nmL is the mass emission of gaseous pollutant corresponding to the applicable limit on the NRTC, g.’;\n(6) in Appendix 8, point 2.8 is replaced by the following:\n‘2.8.\nEngine total swept volume [cm3]’.",
