The key comparison reference value, x_{R}, and its standard uncertainty, u_{R}, 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.
x_{R }=_{ }239.15 and U_{R} = 1.97
The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms:
D_{i} = (x_{i} - x_{R}) and U_{i} = 2[abs(u_{i}^{2} - u_{R}^{2})]^{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.
Linking key comparison APMP.M.H-K1.c to CCM.H-K1.c
