  • Key comparison CCEM-K5
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.
  • Linking EUROMET.EM-K5 to CCEM-K5

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.

  • Linking EUROMET.EM-K5.1 to CCEM-K5

PTB as participant in both comparisons ensures the linkage, which is computed as explained in the EUROMET.EM-K5.1 Linkage Report.

  • Linking SIM.EM-K5 to CCEM-K5

It was possible to link SIM.EM-K5 results to those of CCEM-K5 for the power factors 1.0, 0.5 Lead and 0.5 Lag as explained in the Addendum to the SIM.EM-K5 Final Report.
NIST, NRC, INTI, INMETRO and CENAM ensure the linkage.

It follows that the table of degrees of equivalence relative to the key comparison reference value and the graph of equivalence obtained for CCEM-K5 can be extended to include results from the EUROMET.EM-K5, EUROMET.EM-K5.1 and SIM.EM-K5 participants.
