This standard describes in detail the two main methods used to determine the pore size of separation membranes: the bubble point method and the average Flow rate method. These methods allow for accurate measurement of the pore size of separation membranes, evaluation of their filtrating performance and separation efficiency, and are suitable for different types and applications of separation membranes, including microporous membranes, nanofiltration membranes, and ultrafiltration membranes.
