Abstract
The State Primary Measurement Standard for units of specific gas adsorption, specific surface area, specific volume and pore size of solid substances and materials (GET 210–2014) is currently in operation at UNIIM. The GET 210-2014 has calibration and measurement capabilities for pore size in a range from 2 to 100 nm, while in practice there is a need to control the pore size of solid substances and materials in a range from 100 to 10,000 nm. In order to enhance the calibration and measurement capabilities of the GET 210-2014, it was proposed to include two reference systems implementing the methods of mercury porometry and stationary filtration into the measure...
