no.2 for HEVs at an ATCT test shall not exceed the emission limits applicable to the vehicle tested defined in paragraph 6.3.10. of this Regulation.

              3.8. Calculation and Documentation

              3.8.1. The family correction factor, FCF, shall be calculated as follows:

              FCF = MCO2,Treg / MCO2,23°

              where

                     MCO2,23° is the CO2 emission of the average of all applicable Type 1 tests at 23 °C of vehicle H, after Step 3 of Table A7/1 of Annex B7 for pure ICE vehicles and after Step 3 of Table A8/5 of Annex B8 for OVC-HEVs and NOVC-HEVs, but without any further corrections, g/km;

                     MCO2,Treg  is the CO2 emission over the complete WLTC cycle of the test at regional temperature after Step 3 of Table A7/1 of Annex B7 for pure ICE vehicles and after Step 3 of Table A8/5 of Annex B8 for OVC-HEVs and NOVC-HEVs but without any further corrections, g/km. For OVC-HEVs and NOVC-HEVs, the KCO2 factor as defined in Appendix 2 to Annex B8 shall be used.

              Both MCO2,23° and MCO2,Treg shall be measured on the same test vehicle.

              The FCF shall be included in all relevant test reports.

              The FCF shall be rounded to 4 points of decimal.

              3.8.2. The CO2 values for each pure ICE vehicle within the ATCT Family (as defined in paragraph 2.3. of this Annex B6a) shall be calculated using the following equations:

              MCO2,c,5 = MCO2,c,4 × FCF

              MCO2,p,5 = MCO2,p,4 × FCF

              where

                          MCO2,c,4 and MCO2,p,4 are the CO2 emissions over the complete WLTC, c, and the cycle phases, p, resulting from the previous calculation step, g/km;

                          MCO2,c,5 and MCO2,p,5 are the CO2 emissions over the complete WLTC, c, and the cycle phases, p, including the ATCT correction, and shall be used for any further corrections or any further calculations, g/km;

              3.8.3. The CO2 values for each OVC-HEV and NOVC-HEV within the ATCT Family (as defined in paragraph 2.3. of this Annex B6a) shall be calculated using the following equations:

              MCO2,CS,c,5 = MCO2,CS,c,4 × FCF

              MCO2,CS,p,5 = MCO2,CS,p,4 × FCF

              where

                            MCO2,CS,c,4 and MCO2,CS,p,4 are the CO2 emissions over the complete WLTC, c, and the cycle phases, p, resulting from the previous calculation step, g/km;

                            MCO2,CS,c,5 and MCO2,CS,p,5 are the CO2 emissions over the complete WLTC, c, and the cycle phases, p, including the ATCT correction, and shall be used for any further corrections or any further calculations, g/km.

              3.8.4. If a FCF is less than one, it is deemed to be equal to one, in the case of the worstcase approach, in accordance with paragraph 4.1 of this Annex B6a.

              3.9. Provision for cool down

              3.9.1. For the test vehicle serving as a reference vehicle for the ATCT Family and all vehicles H of
