1.1 These test methods cover the determination of the physical and chemical properties of ion-exchange resins when used for the treatment of water. They are intended for use in testing both new and used materials. The following thirteen test methods are included:

Sections Test Method A--Pretreatment 6 to 10 Test Method B--Water Retention Capacity 11 to 17 Test Method C--Backwashed and Settled Density 18 to 24 Test Method D--Particle Size Distribution 25 to 32 Test Method E--Salt-Splitting Capacity of Cation- 33 to 41 Exchange Resins Test Method F--Total Capacity of Cation-Exchange 42 to 50 Resins Test Method G--Percent Regeneration of Hydrogen- 51 to 58 Form Cation-Exchange Resins Test Method H--Total and Salt-Splitting Capacity of 59 to 66 Anion-Exchange Resins Test Method I--Percent Regeneration of Anion Ex- 67 to 75 change Resins Test Method J--Ionic Chloride Content of Anion- 76 to 83 Exchange Resins Test Method K--Carbonate Content of Anion-Ex- 84 to 91 change Resins Test Method L--Sulfate Content of Anion Exchange 92 to 99 Resins Test Method M--Total Anion Capacity of Anion- 100 to 108 Exchange Resins
