Pore size distribution and porosity of solid materials by mercury porosimetry and gas adsorption - Analysis of micropores by gas adsorption Ingestion-build-183098 A rotary potentiometer (Pot) is1 Scope This part of ISO 15901 describes methods for the evaluation of the volume of micropores (pores of internal width less than 2 nm) and the specific surface area of microporous material by low temperature adsorption of gases [1],[2],[3],[4],[5],[6],[7]. These are comparative, non destructive tests. The methods use physisorbing gases that can penetrate into the pores under investigation. The method is applicable to isotherms of type I, II, IV or
