Abstract

The uncertainty calculation in the calibration of volumetric instruments is normally performed with the classical approach of the “mainstream GUM”. In order to validate the obtained results, since there is a degree of non linearity involved in handling the corresponding expression of volume, a Monte Carlo method was used as a second approach for calculation of that measurement uncertainty. The results of this comparison and corresponding conclusions are presented.
