The key comparison reference value, xR, is calculated as the weighted average of the mean relative deviations from the pilot laboratory obtained by the participating laboratories. Its standard uncertainty, uR, is calculated as explained on page 30 of the CCM.F-K2.a and CCM.F-K2.b Final Report.
xR = 0.47 × 10-5 uR = 0.33 × 10-5
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 × 10-5:
Di = (xi - xR) and its expanded uncertainty Ui at a 95 % level of confidence calculated as the sum in quadrature of the uncertainty associated with the deviation from the pilot value and the uncertainty of the KCRV (see page 32 of the CCM.F-K2.a and CCM.F-K2.b Final Report .
