Vacuum system of Watt-balance: development aspects

Abstract

This paper considers issues related to the development of the vacuum system of Watt-balance for the newest Russian Federation primary standard of the kilogram. The authors give a list of the necessary data for the development of the vacuum system of the newest Russian Federation kilogram mass standard, relying on the generally accepted methods of vacuum systems calculation. This paper shows the main stages of theoretical and practical research work conducted in D. I. Mendeleyev Institute for Metrology (VNIIM) with the use of the vacuum mass comparator Sartorius CCL 1007from the composition of the state primary measurement standard of mass unit - kilogram GET 3-2020, aimed at developing a vacuum system for the newest standard of the kilogram - Watt-balance. The presented results of the research allow for the development of the vacuum Watt-balancing system.
