Application of the EURACHEM method
Pipettes: metrological control Pipettes calibration by the users

Uncertainty calculations can be carried out, as suggested in the EURACHEM/CITAC guide, using an approximate method published by Kragten. The spreadsheet application is very simple and is presented below.

This method makes it possible to estimate the compound standard uncertainty without using partial derivatives to determine the values of the sensitivity coefficients.

The conditions concerning the pipette tested and the balance used for this method are identical to those for the GUM method presented in paragraph
