THE ENHANCEMENT OF METROLOGICAL SUPPORT THE COATING THICKNESS MEASUREMENTS
(pp. 36-39)

Abstract. The article shows an improved hierarchy scheme in the field of coating thickness measurements, which was revised due to inclusion to Federal Information Fund for Ensuring the Uniformity of Measurements more than a hundred new types of Russian and foreign thickness gauges based on of different operating principles. The range of measurements has expanded and accuracy has been improved. It is shown that about 40 % of the approved types of thickness gauges are measuring instruments of foreign production. For responsible groups of materials (nickel on steel and nickel on bronze), only foreign coating thickness gauges are used. To improve the unity of measurements of the coatings thickness, it was necessary to expand the measurement ranges of the reference measuring standards and thickness gauges from 0 to 120 000 microns, as well as the introduction of new measuring standards borrowed from other hierarchy schemes. The article provides the necessary reference measuring standards and thickness gauges, methods for transmitting a unit of length, measuring ranges and measurement errors.

Keywords: hierarchy scheme, traceability, measurement standard, thickness gauge, accuracy.
