Directorate of Measures and Precious Metals, as of 2017, starts the production of Certified Reference Materials (CRMs)– ethanol in water solutions, for the purpose of calibration and/or verification of measuring instruments (alcometeres, breath analyzers).

Reference materials are in dark glass bottles, 1 L volume.

Each RM is accompanied by a Calibration Certificate for the given concentration. Available concentrations can be seen in Catalogue of Services (II CERTIFIED REFERENCE MATERIALS).

This activity, or a new service, was realized by the Group for Metrology in Chemistry, Laboratory for Reference Materials.
