UpcomingEvaluation of pore size distribution and porosity of solid materials by mercruy poresimetry and gas adsorption—Part 1:Mercury porosimetry
压汞法和气体吸附法测定固体材料孔径分布和孔隙度 第1部分：压汞法
Application Summary AI generated
This standard specifies the mercury porosimetry method for determining the pore size distribution, total pore volume, and porosity of solid materials. It is applied in industries such as catalysis, ceramics, construction materials, and filtration, where accurate characterization of macro- and mesopores (typically 0.003 to 400 µm) is critical for quality control and performance evaluation. The method is used in laboratory testing contexts to assess material properties like permeability, adsorption capacity, and structural integrity.
