The global mechanisms of modern society, including the formation of a global market and the expansion of foreign and domestic trade have led to increased demands on the quality of products and services. Information about the quantity and quality of manufactured products is obtained as a result of measurements. Metrological activity has a significant impact on the acceleration of scientific and technological progress, improvement of product quality and production efficiency. Therefore, the interrelation of the level of metrological support with indicators of product quality, rational use of energy and raw material resources is obvious. All this causes growth of requirements to the accuracy of used measures (mass, length, volume).
