MEASURAND : Density of liquids
LIQUID : Pentadecane at 40 °C

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.

MEASURAND : Density of liquids
LIQUID : Pentadecane at 60 °C

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 = 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.
