Scope

This standard specifies a method for measuring the volume change of ion exchange resins when they transition from one ionic state to another. This standard is applicable to the determination of the swelling rate of various types of ion exchange resins during their transformation. For resins containing a large number of weak functional groups, the determination can be carried out according to the method for weak functional resins.
