| The key comparison reference value, xR, is computed as the median of the results. Its expanded uncertainty UR is approximately given at a 95% level of confidence. The details are explained in Appendix C of the CCM.FF-K4 Final Report. xR = 99.8942 mL and UR = 0.0012 mL |
| The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms, both expressed in relative value: Di = (xi - xR)/xR and its expanded uncertainty Ui at approximately a 95% level of confidence. |
| 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 EUROMET reference value, xR-EUR, and its expanded uncertainty (k = 2), UR-EUR, are obtained from the weighted average of the EUROMET participants' results that are published here. xR-EUR = 100.0914 mL and UR-EUR = 0.0006 mL. |
| The degree of equivalence of laboratory i participant in EUROMET.M.FF-K4 with respect to the EUROMET reference value is given by a pair of terms, both expressed in mL: Di-EUR = (xi-EUR - xR-EUR) and its expanded uncertainty (k = 2), Ui-EUR, computed as Ui-EUR = 2[ui-EUR2 - (UR-EUR/2)2]1/2. |
| The degree of equivalence between two laboratories i and j is given by a pair of terms, both expressed in mL: Dij = (Di-EUR - Dj-EUR) and its expanded uncertainty (k = 2), Uij, expressed as Uij = 2(ui-EUR2 + uj-EUR2)1/2. |
The EUROMET.M.FF-K4 results are linked to those obtained at 100 mL in CCM.FF-K4 with the Transfer standard TS 03.04.03.
The technical protocols and transfer standards of both comparisons are very similar, and INRIM and SP participated in both exercises with comparable performance.
The degrees of equivalence relative to the EUROMET reference value are thus transferred to the key comparison reference value determined in CCM.FF-K4 with slight changes. The resulting values of Di, Ui, Dij, and Uij are listed in Annexes 3, 4, and 5 of the EUROMET.M.FF-K4 Final Report.
The matrix of equivalence obtained at 100 mL in CCM.FF-K4 with the Transfer standard TS 03.04.03 is thus extended to EUROMET.M.FF-K4 participants (after conversion to relative values).
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 18 of the APMP.M.FF-K4 Final Report.
