Florbela A. Dias, Tânia Farinha, Fátima Dias, Eduarda Filipe
Abstract:
In recent decades the ethanol metrology has became of significant importance, particularly in the area of individual's blood alcohol control.
Portuguese Institute for Quality is responsible for the calibration and metrological control of breath analyzers. This is done by means of comparison with mixtures of certified reference materials, which are traceable to IPQ and NMi primary standards.
This work aims to demonstrate the importance that the operations of calibration and metrological control of breath analyzers has in our society today, and also to present the calibration and verification procedure, errors calculations and the estimation of expanded uncertainties.
