CCAUV.V-K3
The computation of the key comparison reference value at each frequency, xR,M, and of its expanded uncertainty, UR,M (k = 2), is explained in Section 8 of the Final Report and is based on a weighted mean.
| The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: Di where Di = xi - xR,M, and its expanded uncertainty Ui (k = 2), computed as explained in Section 8 of the Final Report. |
| Pair-wise degrees of equivalence may be calculated taking into account possible correlations. |
