This test method covers the determination of the performance of particulate mixed bed ion exchange materials in the regenerated form when used for deionization.
Formerly under the jurisdiction of Committee D19 on Water, this practice was withdrawn in April 2016 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This test method covers the determination of the performance of particulate mixed bed ion exchange materials in the regenerated form when used for deionization. It is intended for use in testing unused mixed bed materials and samples of regenerated mixed beds from operating units.
1.2 This standard does not purport to address all of the safety concerns, 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.
