The key comparison reference value xR is calculated as the weighted mean of the results of all participants in CCEM-K11. The value of the mean of the seven results of SP is used for the computation of xR, see equations 10 and 11 of the Final Report. The standard uncertainty uR of xR is computed as explained in section 6.1.4 of the Final Report.
xR = 1.6 µV/V 2uR = 9.2 µV/V
The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in µV/V:
Di = (xi - xR)/xR and its expanded uncertainty Ui at a 95 % level of confidence where Ui = 2 ui.

The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in µV/V:
Di = (xi - xR)/xR and its expanded uncertainty Ui at a 95 % level of confidence where Ui = 2 ui.
