MEASURAND : Effective area A' (p', 20 °C) of piston-cylinder unit DH-Budenberg 4603 mounted in a DH-Budenberg pressure balance model 5306 determined from comparisons against participants primary pressure standards
NOMINAL VALUE : 2 mm2
NOMINAL PRESSURE : p' = 50 MPa

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 MED |xi - xR| / (n - 1)1/2, where MED means median and n is the number of participants.

xR = 1.961152 mm2
uR / xR = 13.5 10-6

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms:
Di = (xi - xR) / xR, the relative deviation from the reference value, and
Ui = 2(ui2 + uDC2 + uR2)1/2 / xR, its expanded uncertainty (k = 2).

When required, the degree of equivalence between two laboratories i and j is given by a pair of terms:
Dij = Di - Dj = (xi - xj) / xR, the relative difference between their results, and
Uij = 2(ui2 + uj2 + uDC2)1/2 / xR, its expanded uncertainty (k = 2).

No pair-wise degrees of equivalence are displayed here, but they can be found in the relevant Final Report.

MEASURAND : Effective area A' (p', 20 °C) of piston-cylinder unit DH-Budenberg 4603 mounted in a DH-Budenberg pressure balance model 5306 determined from comparisons against participants primary pressure standards
NOMINAL VALUE : 2 mm2
NOMINAL PRESSURE : p' = 300 MPa

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 MED |xi - xR| / (n - 1)1/2, where MED means median and n is the number of participants.

xR = 1.961688 mm2
uR / xR = 5.9 10-6

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms:
Di = (xi - xR) / xR, the relative deviation from the reference value, and
Ui = 2(ui2 + uDC2 + uR2)1/2 / xR, its expanded uncertainty (k = 2).

When required, the degree of equivalence between two laboratories i and j is given by a pair of terms:
Dij = Di - Dj = (xi - xj) / xR, the relative difference between their results, and
Uij = 2(ui2 + uj2 + uDC2)1/2 / xR, its expanded uncertainty (k = 2).

No pair-wise degrees of equivalence are displayed here, but they can be found in the relevant Final Report.

  • Key comparison CCM.P-K13

MEASURAND : Effective area A' (p', 20 °C) of piston-cylinder unit DH-Budenberg 4603 mounted in a DH-Budenberg pressure balance model 5306 determined from comparisons against participants primary pressure standards
NOMINAL VALUE : 2 mm2
NOMINAL PRESSURE : p' = 450 MPa

xi : result of measurement of A' (p', 20 °C) taken as the arithmetic average of 10 values obtained by laboratory i and corrected for drift
ui : combined standard uncertainty of xi as reported by laboratory i (without including uncertainty of the drift correction)
uDC : standard uncertainty of the drift correction of xi
uDC / xi = 2.1 x 10-6

 Lab i xi
