Uncertainty of Measurement Alcohol Concentration with Evidential Breath Analysers
2023 XXXIII International Scientific Symposium Metrology and Metrology Assurance (MMA)(2023)
摘要
Evidential breath analysers are used to determine the alcohol concentration of motor vehicle drivers and are subject to legally defined metrological control. The legislator has provided for a coercive administrative measure and administrative penalties for those who violate the traffic rules. The main argument in the appeal of the act imposing the measures and punishments is the measured values of the alcohol concentration by the breath alcohol analyser. The purpose of the report is to present the accuracy and sources of uncertainty in the measurement of alcohol concentration with breath alcohol analysers.
