1.1 These test methods cover the determination of the operating capacity of particulate cation-exchange materials when used for the removal of calcium, magnesium, and sodium ions from water. It is intended for use in testing both new and used materials. The following two test methods are included:
| Sections | |
| Test Method A—Sodium Cycle | 8 to 14 |
| Test Method B—Hydrogen Cycle | 15 to 21 |
1.2 The values given in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.3 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. 8.1 This test method is designed to simulate operating conditions on a sodium cycle used for the removal of calcium and magnesium and other divalent ions from water. 15.1 This test method is designed to simulate operating conditions on a hydrogen cycle used for the removal of all other cations from water.
