CCEM.RF-K10.CL and EUROMET.EM.RF-K10.CL

  • Key comparison CCEM.RF-K10.CL

MEASURAND : Calibration factor
TRANSFER STANDARD : Power sensors PTB 1-3 and PTB 1-3-1
FREQUENCY : 50 MHz

The computation of the key comparison reference values, xR, and of their uncertainties, uR, is explained in Section 6.2 of the Final Report (pages 14 and 15).
For each frequency and each of the transfer standards PTB 1-3 and PTB 2-6, xR is computed as the unweighted arithmetic mean of the participants' results obtained using independant primary power standards with outliers excluded. Its standard uncertainty, uR, is the standard deviation of the mean.
For each frequency and each of the repaired transfer standards PTB 1-3-1 and PTB 2-6-1, xR is computed using the common measurements carried out by PTB (see on page 15 of the Final Report). Its standard uncertainty, uR, is assumed to be equal to the standard uncertainty obtained with the transfer standard before repair.

For PTB 1-3, xR = 0.9866 and uR = 0.0010
For PTB 1-3-1, xR = 0.9895 and uR = 0.0010

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by two terms, both expressed in 10-3: Di = (xi - xR) and its expanded uncertainty Ui (k = 2), Ui = 2(ui2 + uR2)1/2.

The degree of equivalence between two laboratories i and j is given by two terms, both expressed in 10-3: Dij = (Di - Dj) and its expanded uncertainty Uij (k = 2),
Uij = 2(ui2 + uj2)1/2.
  • Linking EUROMET.EM.RF-K10.CL to CCEM.RF-K10.CL

The laboratories that are participants in both comparisons (PTB and NPL) are used for linking the results obtained in EUROMET.EM.RF-K10.CL to the results obtained in CCEM.RF-K10.CL. The linking process is explained in section 6.2 of the EUROMET.EM.RF-K10.CL Final Report.

The degree of equivalence of laboratory i participant in EUROMET.EM.RF-K10.CL with respect to the key comparison reference value is given by two terms, both expressed in 10-3: Di and its expanded uncertainty Ui (k = 2).
The degree of equivalence is computed as explained in section 6.3 of the EUROMET.EM.RF-K10.CL Final Report.

The degree of equivalence between two laboratories i and j is given by two terms, both expressed in 10-3: Dij and its expanded uncertainty Uij (k = 2).
The pair-wise degrees of equivalence are computed only between two laboratories participants in EUROMET.EM.RF-K10.CL.

FREQUENCY : 20 GHz

The computation of the key comparison reference values, xR, and of their uncertainties, uR, is explained in Section 6.2 of the Final Report (pages 14 and 15).
For each frequency and each of the transfer standards PTB 1-3 and PTB 2-6, xR is computed as the unweighted arithmetic mean of the participants' results obtained using independant primary power standards with outliers excluded. Its standard uncertainty, uR, is the standard deviation of the mean.
For each frequency and each of the repaired transfer standards PTB 1-3-1 and PTB 2-6-1, xR is computed using the common measurements carried out by PTB (see on page 15 of the Final Report). Its standard uncertainty, uR, is assumed to be equal to the standard uncertainty obtained with the transfer standard before repair.

For PTB 2-6, xR = 0.8960 and uR = 0.0016
For PTB 2-6-1, xR = 0.9110 and uR = 0.0016

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by two terms, both expressed in 10-3: Di = (xi - xR) and its expanded uncertainty Ui (k = 2), Ui = 2(ui2 + uR2)1/2.

The degree of equivalence between two laboratories i and j is given by two terms, both expressed in 10-3: Dij = (Di - Dj) and its expanded uncertainty Uij (k = 2),
Uij = 2(ui2 + uj2)1/2.
  • Linking EUROMET.EM.RF-K10.CL to CCEM.RF-K10.CL

The laboratories that are participants in both comparisons (PTB and NPL) are used for linking the results obtained in EUROMET.EM.RF-K10.CL to the results obtained in CCEM.RF-K10.CL. The linking process is explained in section 6.2 of the EUROMET.EM.RF-K10.CL Final Report.

The degree of equivalence of laboratory i participant in EUROMET.EM.RF-K10.CL with respect to the key comparison reference value is given by two terms, both expressed in 10-3: Di and its expanded uncertainty Ui (k = 2).
The degree of equivalence is computed as explained in section 6.3 of the EUROMET.EM.RF-K10.CL Final Report.

The degree of equivalence between two laboratories i and j is given by two terms, both expressed in 10-3: Dij and its expanded uncertainty Uij (k = 2).
The pair-wise degrees of equivalence are computed only between two laboratories participants in EUROMET.EM.RF-K10.CL.

It follows that the Matrix of equivalence and the Graph of equivalence obtained for CCEM.RF-K10.CL are extended with results obtained in EUROMET.EM.RF-K10.CL.
