The comparison reference value is computed as a median as explained in Section 5 of the Final Report. The uncertainty of the key comparison reference value is computed as given in equations 7 and 8 of the report and is equal to 37 µg for nominal mass of 2 kg and transfer standard Jx. |
| The degree of equivalence of each laboratory i 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 µg, computed as explained in equations 6, 9 and 10 of the report. |
| No pairwise degree of equivalence is given. |
The common participation of VNIIM makes it possible to link the COOMET.M.M-K5 results to those of CCM.M-K5 (see Section 4.3 of the COOMET.M.M-K5 Final Report), using the VNIIM results for the CCM.M-K5 standards 2 kg-Jx, 200 g-Jy, 1 g-Jy and 200 mg-Jy.
In CCM.M-K5, the VNIIM results for the weights with nominal values 50 g were not consistent with the key comparison reference values. Thus the results of measurements for this value have been excluded from the computation of the degrees of equivalence of COOMET.M.M-K5 participants.
Pair-wise degrees of equivalence involving COOMET.M.M-K5 participants (only) have not been computed.
The linking was made via the CENAM, INMETRO and the NRC that all participated in the CCM.M-K5 comparison. The Degrees of Equivalence for SIM.M.M-K5 were evaluated against the average results of CENAM, INMETRO and the NRC obtained for the Jx and Jy mass standards in the CCM.M-K5 comparison. The DoE have been reproduced in the tables and graphs for Jx (2 kg) and Jy (200 g, 50 g, 1 g, 200mg)
