1.1 This guide presents a series of tests and evaluations intended to detect fouling and degradation of particulate ion exchange materials. Suggestions on reducing fouling and on cleaning resins are given.

1.2 This guide is to be used only as an aid in the evaluation of particulate ion exchange material performance and does not purport to address all possible causes of unsatisfactory performance. The evaluations of mechanical and operational problems are not addressed.

1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
