The key comparison reference value, x_{R}, is calculated as the median of the participants' values. The standard uncertainty of the key comparison reference value, u_{R}, is calculated by the formula u_{R} = 1.858 MED x_{i}  x_{R} / (n  1)^{1/2}, where MED means median and n is the number of participants. 
The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: D_{i} = (x_{i}  x_{R}) / x_{R}, the relative deviation from the reference value, and U_{i} = 2(u_{i}^{2} + u_{DC}^{2} + u_{R}^{2})^{1/2} / x_{R}, its expanded uncertainty (k = 2). 
When required, the degree of equivalence between two laboratories i and j is given by a pair of terms: No pairwise degrees of equivalence are displayed here, but they can be found in the relevant Final Report.

MEASURAND : Effective area A' (p', 20 °C) of pistoncylinder unit DHBudenberg 4603 mounted in a DHBudenberg pressure balance model 5306 determined from comparisons against participants primary pressure standards
NOMINAL VALUE : 2 mm^{2}
NOMINAL PRESSURE : p' = 400 MPa
The key comparison reference value, x_{R}, is calculated as the median of the participants' values. The standard uncertainty of the key comparison reference value, u_{R}, is calculated by the formula u_{R} = 1.858 MED x_{i}  x_{R} / (n  1)^{1/2}, where MED means median and n is the number of participants. 
The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: D_{i} = (x_{i}  x_{R}) / x_{R}, the relative deviation from the reference value, and U_{i} = 2(u_{i}^{2} + u_{DC}^{2} + u_{R}^{2})^{1/2} / x_{R}, its expanded uncertainty (k = 2). 
When required, the degree of equivalence between two laboratories i and j is given by a pair of terms: No pairwise degrees of equivalence are displayed here, but they can be found in the relevant Final Report.
