QUALITY ASSURANCE OF BREATH ALCOHOL MEASUREMENTS

Mirela Adelaida Anghel, Fãnel Iacobescu

Abstract

Romania, as a member state of European Union, started to develop together with its National Institute of Metrology, efficient measures to detect drivers under influence with accurate results and to assure the traceability of mass concentration of alcohol in exhaled breath. The paper describes the complete system used for testing of ethylometers performance and the method applied to prepare and certify the standard solutions. The expanded uncertainty for the complete simulator system was calculated taking into consideration all input quantities which have noticeable contribution to the final uncertainty.
