For each measurement, electric balance during the test and the measured CO2-emissions shall be recorded.\nIn order to evaluate the statistical error of K CO 2 , all T combinations without repetitions of T-1 measurements shall be used to extrapolate T different values of K CO 2 (i.e. K 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.\nThe standard deviation of K CO 2 s K CO 2 – shall be calculated in accordance with Formula 8.",
