The key comparison reference value xR and its associated expanded uncertainty at a 95% level of confidence, UR are calculated according to section 5 of the CCM.D-K2 Final Report, where the key comparison reference value is computed by a Monte Carlo method using the median. The distribution is usually non-symmetric and the confidence interval may not be equally spaced around the reference value.

        xR = 998.3220 kg/m3     UR lower = 0.0038 kg/m3  and  UR upper = 0.0038 kg/m3

The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in kg/m3:

Di and its expanded uncertainty Ui at a 95 % level of confidence are calculated by the Monte Carlo method according to section 8 of the CCM.D-K2 Final Report.

The degree of equivalence, Di, of laboratory i with respect to the key comparison reference value is calculated as the offset to xR together with its expanded uncertainty Ui = 2(ui2uR2)1/2, where ui and uR are the standard uncertainties of the laboratory result and of the key comparison reference value, respectively.

The key comparison reference value, xR , and associated expanded uncertainty at a 95% level of confidence, UR, are calculated according to Procedure A explained in Metrologia, 2012, 39, 589-595 (see page 17 of the Final Report). It is the weighted mean of the results.

xR = 754.5871 kg/m3, UR = 0.0040 kg/m3

The degree of equivalence, Di, of laboratory i with respect to the key comparison reference value is calculated as the offset to xR together with its expanded uncertainty Ui = 2(ui2uR2)1/2, where ui and uR are the standard uncertainties of the laboratory result and of the key comparison reference value, respectively.

xR = 740.6078 kg/m3, UR = 0.0048 kg/m3

The degree of equivalence, Di, of laboratory i with respect to the key comparison reference value is calculated as the offset to xR together with its expanded uncertainty Ui = 2(ui2uR2)1/2, where ui and uR are the standard uncertainties of the laboratory result and of the key comparison reference value, respectively.
