Division Formula 7

Where:

The CO₂-emission correction factor $K_{{\mathrm{CO}}_2}$ shall be determined from a set of T measurements performed by the manufacturer, in accordance with paragraph 2.2 of Appendix 2 to Sub-Annex 8 to Annex XXI to Regulation (EU) 2017/1151. For each measurement, electric balance during the test and the measured CO₂-emissions shall be recorded.

In order to evaluate the statistical error of $K_{{\mathrm{CO}}_2}$ , all T combinations without repetitions of T-1 measurements shall be used to extrapolate T different values of $K_{{\mathrm{CO}}_2}$ (i.e. $K_{{\mathrm{CO}}_{2_t}}$ ). The extrapolation shall be performed in accordance with the method defined in paragraph 2.2 of Appendix 2 to Sub-Annex 8 to Annex XXI to Regulation (EU) 2017/1151.

The standard deviation of $K_{{\mathrm{CO}}_2}$ $\left(s_{\stackrel{–}{K_{{\mathrm{CO}}_2}}}\right)$ shall be calculated in accordance with Formula 8.
