ENSURING UNIFORMITY OF HARDNESS MEASUREMENTS BY THE DYNAMIC METHOD IN THE RUSSIAN FEDERATION
(pp. 44-49)

Abstract. The article deals with problems of metrological assurance of hardness measurements by the method of Leeb in the Russian Federation. Classification of hardness measurement techniques and essence of Leeb hardness measurements are considered. The difference of dynamic hardness measurement methods in metrological assurance in the Russian Federation and in the world practice are clarified. The need to revise the current calibration and verification scheme and dynamic hardness testers application are justified. The influence of the transducer parameters on the measurement results, such as impact velocity, are reviewed. The results of Leeb hardness measurements on Brinell reference test block and Leeb reference test block are compared. Based on the current verification scheme for dynamic hardness testers the generalized structure of the metrological traceability scheme for the determination and dissemination of Leeb hardness scales as a basis of the verification scheme, which provides true quantity value, is proposed.

Keywords: hardness, dynamic hardness, Leeb, metrological assurance.
