Scope

This standard specifies the method for determining the volume change of ion exchange resins when they change from one ionic state to another. This standard is applicable to the determination of the conversion expansion ratio of various types of ion exchange resins. For resins containing more weak-type groups, it can be measured as weak-type resins.
