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
                                                uR = 0.000 9 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 + uT2)1/2, its expanded uncertainty (k = 2). uT is the uncertainty due to the instability of the transfer standard: uT = 0.002 5 mm2 (see page 15 of the Final Report).

The degree of equivalence between two laboratories i and j is given by a pair of terms expressed in mm2Dij = Di - Dj = (xi - xj) and Uij = 2(ui2 + uj2 + 2uT2)1/2, its expanded uncertainty (k = 2). Effects of correlation should be taken into consideration.

Di = (xi - xR) and Ui = 2(ui2 + uR2 + uT2)1/2, its expanded uncertainty (k = 2). uT is the uncertainty due to the instability of the transfer standard: uT = 0.002 5 mm2 (see page 15 of the Final Report).
