T1 - Certified reference materials for breath alcohol control – the ALCOREF project N2 - ALCOREF is a project within the European Metrology Programme for Innovation and Research (EMPIR. It is part of the 2016 EMPIR Research Potential Call dedicated to build up metrological and research capacity in less developed National Metrology Institutes (NMIs). The project will develop long term expertise for the production and certification of ethanol/water reference materials in the participating NMIs. Materials to be developed will be suitable for the calibration and approval of evidential breath alcohol analysers as defined by recommendation R 126 of the International Organization of Legal Metrology (OIML). Certification includes the characterisation of the materials, assessment of homogeneity, stability and uncertainty. Target certified values and volumes will address end-users’ needs regarding regional legal limits for alcohol in traffic and the instrumentation for breath analyser calibration available in different countries. Thus, the project supports the law enforcement of national drink-driving legislation. The consortium comprises of 11 institutions from 10 European countries. Project participants will establish reliable analytical methods for the purity assessment of ethanol, such as Karl-Fischer titration, to achieve traceability of their certified values. Chromatographic or density methods for the quantification of ethanol in water will also be established, validated and applied for homogeneity and stability assessment. An interlaboratory comparison will be conducted within the European Association of National Metrology Institutes’ (EURAMET) Technical Committee Metrology in Chemistry to test the equivalence of the new certified reference materials and the analytical methods implemented. The poster will present the outline and first results of the ALCOREF project.
