Abstract
The article presents the results of research aimed at the selection of materials for the production of new reference materials intendedfor verification, calibration, and testing for type approval of means of measuring the viscosity of liquids, as well as certification of methods for measuring the viscosity of liquid media at temperatures below 0 °C. The developed reference materials are certified in the interval of allowed temperature values from -40 °C to -5 °C. This allows providing a wide range of modern methods for measuring the viscosity of liquids such as glass capillary viscometers, rotational viscometers, rheometers, etc.
