Head Kosterov Oleksandr О., Доктор філософії Registration Date 24-01-2025 Organization State scientific-research institute of metrology of measuring and control systems popup.description1 The purpose of the NDR is to study the stability of reproduction and storage of units of measurement by national state primary standards during their maintenance and application, to ensure the unity and traceability of measurements of the unit of sound pressure in the air environment, the unit of ultrasonic pressure in the water environment and the unit of ultrasound power in the water environment in the state; transfer of the dimensions of measurement units, which are reproduced and stored by national standards, to the means of measuring equipment used in the territory of Ukraine. popup.description2 Work within the framework of the NDR was aimed at researching the stability of reproduction and storage of units of measurement by three national standards: – the national standard of the unit of sound pressure in the air environment of NDETU AUV-03-2019; – the national standard of the unit of ultrasonic power in the water environment of NDETU AUV-01- 2018; - the national standard of the unit of ultrasonic pressure in the water environment of NDETU AUV-02-2018. Carrying out the above-mentioned works made it possible to ensure the stability of reproduction, storage and transmission of the size of the unit of sound pressure (Pa) in the air environment, the unit of ultrasonic pressure (Pa) in the water environment and the unit of ultrasound power (W) in the water environment by state primary standards and to create conditions for ensuring unity and traceability of acoustic measurements in Ukraine. According to the results of the NDR, the studied national standards meet the standards established in the technical documentation for standards and are suitable for use in the indicated ranges of the main parameters.
