Information × Registration Number 0221U103784, 0120U103907 , R & D reports Title Development of the State Primary Standard unit of moisture content of solid materials popup.stage_title Head Kulik Sergyi V., Registration Date 25-02-2021 Organization Subsidiary of the All-Ukrainian State Scientific and Technical Center for Standardization, Metrology, Certification and Certification of Rights popup.description2 The following were performed: additional analysis of sources of errors of results obtained with the help of reference units of air-heat and high-temperature vacuum drying, and which are related to the weighing process; experimental studies to estimate the magnitude of the uncertainty of the mass of the boxes associated with their periodic heating and cooling; experimental studies to assess the magnitude of the uncertainty of the measurement result of humidity associated with the loss of moisture in the test material during selection, transfer, weighing the sample before and after drying; the start-up was performed and the convergence of the results obtained with the help of the reference installation of high-temperature vacuum drying was evaluated, and on the basis of the acquired experience, measures were taken to improve the design of the installation. The obtained results are an essential basis for further work to create a standard, optimize the procedure for measuring humidity and improve the metrological characteristics of the standard.  Product Description popup.authors popup.nrat_date 2021-02-25 Close
