Information × Registration Number 0220U000159, 0119U001885 , R & D reports Title Creation of the State Primary Standard of unit of kinematic viscosity of liquids popup.stage_title Head Gavrylkin Volodymyr Georgyiovych, Registration Date 21-01-2020 Organization Ukrainian State Research and Production Centre for Standardization, Metrology and Sertification popup.description2 The mathematical model of the error and uncertainty of the reproduction of the unit of measurement at the level of the state primary standard is developed and the characteristics of the mathematical model in the process of calibration of the measuring equipment are investigated. A set of viscometers was purchased for further research, calibration and inclusion in the standard. In the process of calibration of the components of the standard, experimental studies were performed to determine their metrological characteristics in accordance with ISO / TR 3666: 1998 and ASTMD 446-07. Mathematical processing of the results of the experiment to establish the metrological characteristics of the reference viscometers and to determine the uncertainty of the measurement results in accordance with DSTU-H-RMG 43. The scientific and technical researches within the framework of the development of the system of control of the time of liquid leakage are conducted.
