This standard specifies the method for measuring the pore size of porous membranes, using the standard particle method for testing. The standard particle method tests the permeability performance of porous membranes by standard particle objects (usually micron-sized particles) with known particle sizes to determine their pore size. This method is suitable for the determination of pore size of various porous membrane materials, which is helpful for evaluating the filtrating performance of membrane materials and selecting appropriate application scenarios.
