1. Scope
1.1 This test method determines the ratio between the equivalents of anion-exchange capacity and the equivalents of cation-exchange capacity present in a physical mixture of salt-splitting anion-exchange material and salt-splitting cation-exchange material.
1.2 The values stated in SI units are to be regarded as the 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
