MEASURAND   Water volume

NOMINAL VALUE 100 mL

TRANSFER INSTRUMENT   Glass pycnometer, serial number TS 03.01.12

 

The key comparison reference value xR and its associated standard uncertainty uR are computed from the weighted mean of the reported results for the transfer instrument, as explained in Section 8 of the CCM.FF-K4.1.2011 Final report.

 

        xR = 99.643 22 mL     uR = 0.000 33 mL

 

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 10-6:

Di = (xi - xR)/xR and its expanded uncertainty Ui at a 95 % level of confidence also expressed in relative terms.
