GET 217–2018: State Primary Standard of Unit of Mass Fraction and Unit of Mass (Molar) Concentration of Inorganic Components in Aqueous Solutions Based on Gravimetric and Spectral Methods

Аннотация

The metrological characteristics of GET 217–2018, the State Primary Standard of the unit of mass fraction and unit of mass (Molar) concentration of inorganic components in aqueous solutions based on gravimetric and spectral methods, are presented. The composition and operating principle of GET 217–2018 and the method used in reproduction and transmission of the two units are described. Information about international key comparisons is presented.
