The key comparison reference value, xR, and its standard uncertainty, uR, is evaluated by the unified procedure explained in Section 8.2 on page 20 of the CCM.H-K1.c Final Report, based on the arithmetic mean of the participants'' results with exclusion of outliers.


xR = 239.15 and UR = 1.97

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms:
Di = (xi - xR) and Ui = 2[abs(ui2 - uR2)]1/2 (where "abs" stands for "absolute value"), its expanded uncertainty (k = 2).

 

Linking key comparison COOMET.M.H-K1.c to CCM.H-K1.c

The linkage is obtained through the common participation of PTB in both key comparisons and is explained in Appendix A3 of the COOMET.M.H-K1.c Final Report. It leads to the computation of the degrees of equivalence of VNIIFTRI relative to the CCM.H-K1.c reference values.
