the arithmetic average of the charge-sustaining CO2 emission of  tests based on the CO2 emission, not corrected for the energy balance, according to the equation below, g/km;
                          is the index number of the considered test;
                          is the total number of tests;
              and:
              The CO2 emission correction coefficient shall be rounded according to paragraph 6.1.8. of this Regulation to four significant figures. The statistical significance of the CO2 emission correction coefficient shall be evaluated by the responsible authority.
              2.3.2.1. It is permitted to apply the CO2 emission correction coefficient developed from tests over the whole applicable WLTP test cycle for the correction of each individual phase.
              2.3.2.2. Additional to the requirements of paragraph 2.2. of this appendix, at the request of the manufacturer and upon approval of the responsible authority, separate CO2 emission correction coefficients  for each individual phase may be developed. In this case, the same criteria as described in paragraph 2.2. of this appendix shall be fulfilled in each individual phase and the procedure described in paragraph 2.3.2. of this appendix shall be applied for each individual phase to determine phase-specific correction coefficients.
              3. Test procedure for the determination of the correction coefficients
              3.1. OVC-HEVs and OVC-FCHVs
              For OVC-HEVs and OVC-FCHVs, one of the following test sequences according to Figure A8.App2/1 shall be used to measure all values that are necessary for the determination of the correction coefficients according to paragraph 2. of this appendix.

3.1.1.1. Preconditioning and soaking
              Preconditioning and soaking shall be conducted according to paragraph 2.1. of Appendix 4 to this annex.
              3.1.1.2. REESS adjustment
              Prior to the test procedure according to paragraph 3.1.1.3. of this appendix, the manufacturer may adjust the REESS. The manufacturer shall provide evidence that the requirements for the beginning of the test according to paragraph 3.1.1.3. of this appendix are fulfilled.
              3.1.1.3. Test procedure
              3.1.1.3.1. The driver-selectable mode for the applicable WLTP test cycle shall be selected according to paragraph 3. of Appendix 6 to this annex.
              3.1.1.3.2. For testing, the applicable WLTP test cycle according to paragraph 1.4.2. of this annex shall be driven.
              3.1.1.3.3. Unless stated otherwise in this appendix, the vehicle shall be tested according to the Type 1 test procedure described in Annex B6.
              3.1.1.3.4. To obtain a set of applicable WLTP test cycles required for the determination of the correction coefficients according to paragraph 2.2. of this appendix, the test may be followed by a number of consecutive sequences in accordance with the requirements of paragraph 3.1.1.1. to paragraph 3.1.1.3.3. inclusive of this appendix.
