Scope
This standard specifies the testing methods for the uniformity of nanofiltration membrane thickness, water flux, ion removal rate, low-molecular-weight organic matter removal rate, and acid and alkali resistance. This standard is applicable to the testing of flat nanofiltration membranes, and other forms of nanofiltration membranes can be referenced for implementation.
