scope:

1.1 These test methods cover the determination of the physical and chemical properties of powdered ion exchange resins and are intended for use in testing new materials. The following test methods are included:

Sections
Test Method A-Particle Size Distribution 5 to 15
Test Method B-Solids Content16 to 23

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This test method covers the instrumental determination of the particle-size distribution of powdered ion exchange resins.

16.1 This test method covers the determination of the percent solids in new powdered ion exchange resins. Both anion resin and cation resin may be tested by this test method. Resins are tested in the ionic form in which they are received.

16.2 It is important to note that ion exchange resins, particularly anion exchange resins in the hydroxide form, are subject to thermal degradation under the conditions of this test. Therefore, volatile degradation products are released along with moisture, resulting in a negative error. However, the value of this test method is that it is simple and reproducible, and it is applicable to as-received samples.
