NOMINAL VALUE: 240 HV
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.b Final Report, based on the arithmetic mean of the participants'' results with exclusion of outliers.
xR = 239.81 and UR = 2.08
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.b to CCM.H-K1.b
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.b Final Report. It leads to the computation of the degrees of equivalence of VNIIFTRI relative to the CCM.H-K1.b reference values.
Linking key comparison APMP.M.H-K1.b to CCM.H-K1.b
The linkage is obtained through the common participation of KRISS, NIM, and NMIJ in both key comparisons and is explained in Section 8.1 of the APMP.M.H-K1.b Final Report.
