Abstract
The article presents the results of a study on the characteristics of non-aqueous solutions aimed at expanding the work range of the State Primary Standard for the Unit of Specific Electrical Conductivity of Liquids GET 132-2018 to low values. The information on the selection of materials and methods for preparing reference solutions as well as on establishing specific electrical conductivity values for reference solutions in the range from 1 · 10−7 to 1 · 10−4 S/m with corresponding measurement uncertainty budgets for reproducing the unit of specific electrical conductivity of liquids is provided.
Keywords
