THREE TRANSFER STANDARDS
|
For each of the transfer standards, the key comparison reference value, xR, is computed either as the median or as the weighted mean of the results. Its expanded uncertainty UR is approximately given at a 95% level of confidence.
|
|
For each transfer standard, a first degree of equivalence for laboratory i with respect to the key comparison reference value is calculated as a pair of terms, both expressed in relative value: |
| The degree of equivalence between two laboratories i and j is given by a pair of terms, both expressed in relative value: Dij = Di - Dj and its expanded uncertainty Uij at approximately a 95% level of confidence. |
The linking process is described in section 7 of the EURAMET.M.FF-K4.b Final Report. The Matrix of equivalence obtained at 20 L in CCM.FF-K4 is thus extended to EURAMET.M.FF-K4.b participants.
Note: The Dij values given in the Annex 2 of the EURAMET.M.FF-K4.b Final Report correspond to -Dij values shown in the Matrix of equivalence.
The regional comparison reference value is first determined as the median of the SIM results for transfer standard TS 710-05, as described in section 8 of the SIM.M.FF-K4 Final Report.
Then the linking process uses common participation of CENAM, NIST and INMETRO in both key comparisons, as described in section 9 of the same Report.
Pair-wise degrees of equivalence involving CCM.FF-K4 and SIM.M.FF-K4 are given on page 16 of the SIM.M.FF-K4 Final Report.
The linking process uses common participation of NMIA and CENAM in both key comparisons, as described in section 7 of the APMP.M.FF-K4 Final Report.
Pair-wise degrees of equivalence involving APMP.M.FF-K4 participants are given on page 17 of the APMP.M.FF-K4 Final Report.
