Comments

Key comparison APMP.AUV.V-K3 was first declared as APMP.AUV.V-S1, then upgraded at the 9th meeting of the CCAUV, 2013, as a "V-K3" key comparison.
This explains the reason why the References provided in this page are related to the identifier "APMP.AUV.V-S1".

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.
