For each measurement, the electricity 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 has to be used to extrapolate T different values of k CO 2 (i.e. k CO 2 t ). The extrapolation shall be performed according to the method defined in Regulation UN/ECE No 101, Annex 8.\nThe standard deviation of k CO 2 S k CO 2 – is thus calculated as defined by Formula 5.",
