| The key comparison reference value, xR, is calculated as the weighted mean of the difference between laboratory i and the predicted value, based on measurements performed at the pilot laboratory. Its standard uncertainty, uR, is calculated as the uncertainty of the weighted mean of the differences. |
xR = 7 µW/VA and uR = 5 µW/VA
| The degree of equivalence of each laboratory with respect to the key comparison reference value is given by a pair of terms: Di and Ui, its expanded uncertainty (k = 2), both expressed in µW/VA. The derivation of these terms can be found in the CCEM-K5 Final Report. |
| When required, the degree of equivalence between two laboratories i and j is given by a pair of terms: Dij and Uij, its expanded uncertainty (k = 2), both expressed in µW/VA. The derivation of these terms can also be found in the CCEM-K5 Final Report. |
The linkage between EUROMET.EM-K5 and CCEM-K5 is computed as explained in the EUROMET.EM-K5 Linkage Report. The INRIM, NPL, PTB and SP participated in both comparisons. The common participants at the exception of SP were used as linking laboratories as explained on page 1 of the Linkage Report.
