适用范围:
This document specifies a test method for determining the mean pore size of separation membranes by gas permeation method.
This document is applicable to the mean pore size test for flat membranes and hollow fiber membranes with a diameter within 0.01μm-0.20μm in dry state, and for other shapes of separation membranes this document may be referred to.
This document is applicable to the mean pore size test with nitrogen as the test gas, and the test with other noncondensable gases, such as He, H2, O2, Ar etc., may refer to this document.
