6. Application of the GUM method
GUM for Guide to the expression of the Uncertainty in Measurement.
The tables in this paragraph show the calculations performed to determine the uncertainty on the volume V 20 of a micropipette with the following characteristics:
nominal volume: 100 × 10 –9 m 3 (100 μL) ;
coefficient of expansion: 4.5 × 10 –4 °C –1 .
The certified instruments used to measure ambient parameters are shown in table
