Traceable gas samples will lead to more reliable breathalyser tests
More widespread alcohol testing for drivers, especially the Baltics and Southern Europe where alcohol related accidents are high, is seen as a key measure in reducing road deaths. Access to breathalysers of agreed standards across Europe is key to this. To accurately calibrate these breathalysers, there is a need for standardised test gases similar to human breath with defined concentrations of alcohol. Currently, only two European NMIs produce such gases.
The project will build production capabilities for ethanol/water reference materials and analytical methods for quantifying ethanol in water at NMIs/DIs across Europe, allowing them to reproducibly create alcohol reference materials traceable to the SI. Each NMI will develop a strategy for the long-term development of their measurement and production capabilities, aligned with a European wide approach. Wider access to certified reference materials will allow manufacturers of breathalysers to meet common standards and so support better enforcement of drink driving laws across Europe.
