MEASURAND Water volume
NOMINAL VALUE 100 µL
The key comparison reference value xR and the associated expanded uncertainty (k = 2) UR for each pipette is basically obtained from the weighted means of the results.
For each micropipette, the degree of equivalence of laboratory i with respect to the key comparison reference value is computed according to equations 8, 9 and 10 on page 11 of the Final Report, and is given by a pair of terms, both expressed in µL: Di and Ui, its expanded uncertainty (k = 2).
