The key comparison reference value, xR, is calculated as the median of the participants' values. The standard uncertainty of the key comparison reference value, uR, is calculated by the formula uR = 1.858 MAD / (n - 1)1/2, where MAD is the median of absolute deviations from the median, and n is the number of participants contributing to the reference value.

xR = 335.744 2 mm2
uR = 0.001 5 mm2

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms expressed in mm2:
Di = (xi - xR) and Ui = 2(ui2 + uR2)1/2, its expanded uncertainty (k = 2).
The degree of equivalence between two laboratories i and j is given by a pair of terms expressed in mm2:
Dij = Di - Dj = (xi - xj) and Uij = 2(ui2 + uj2)1/2, its expanded uncertainty (k = 2).

  • Key comparison CCM.P-K6

The key comparison reference value, xR, is calculated as the median of the participants' values. The standard uncertainty of the key comparison reference value, uR, is calculated by the formula uR = 1.858 MAD / (n - 1)1/2, where MAD is the median of absolute deviations from the median, and n is the number of participants contributing to the reference value.

xR = 335.744 4 mm2

  • Linking APMP.M.P-K6 to CCM.P-K6

PTB is the common participant to both key comparisons CCM.P-K6 and APMP.M.P-K6: its results are used to compute the linkage as explained in Sections 5.1 and 5.2 of the APMP.M.P-K6 Final Report.

Degrees of equivalence relative to the CCM.P-K6 key comparison reference value are obtained for laboratories having participated in APMP.M.P-K6 only, as explained in Section 5.3 of the APMP.M.P-K6 Final Report. They are expressed in mm2.
Pair-wise degrees of equivalence among pairs of participants in APMP.M.P-K6 are obtained as explained in Section 5.4 of the APMP.M.P-K6 Final Report. They are expressed in relative terms.
  • Linking APMP.M.P-K6.1 to CCM.P-K6

The key comparison APMP.M.P-K6.1 is linked to the CCM.P-K6 key comparison through the APMP.M.P-K6 key comparison.
A*STAR is the common participant to both key comparisons APMP.M.P-K6 and APMP.M.P-K6.1: its results are used to compute the linkage as explained in paragraph 4.1 the APMP.M.P-K6.1 Final Report.

Degrees of equivalence relative to the CCM.P-K6 key comparison reference value are obtained for laboratories having participated in APMP.M.P-K6.1 only, as explained in paragraph 4.2 of the APMP.M.P-K6.1 Final Report. They are expressed in mm2.
Pair-wise degrees of equivalence among pairs of participants in APMP.M.P-K6.1 are obtained as explained in paragraph 4.3 of the APMP.M.P-K6.1 Final Report. They are expressed in relative terms.
  • Linking EURAMET.M.P-K8 to CCM.P-K6

PTB and VSL provide the link between key comparisons CCM.P-K6 and EURAMET.M.P-K8 for the following nominal pressures:  25 kPa, 50 kPa, 75 kPa and 100 kPa.
The linkage process is described in Section 11 of the EURAMET.M.P-K8 Final Report.

The measurements of EURAMET.M.P-K8 at the nominal pressure 25 kPa are linked with the averaged value of the 20 kPa and 30 kPa measurements of the CCM comparison, and those at the nominal pressure 75 kPa are linked with the averaged value of the 70 kPa and 80 kPa measurements of the CCM comparison.

Therefore, the degrees of equivalence of the laboratories having participated in EURAMET.M.P-K8 for 25 kPa and 75 kPa are shown on a different graph from the ones for the participants in CCM.P-K6.

 

The results issued by SIM.M.P-K6 are traceable to NIST and as such traceable to CCM.P-K6.
