ASTM D5042-90(1998)

Standard Test Method for Estimating the Organic Fouling of Particulate Anion Exchange Resins

SCOPE
1.1 This test method provides a general estimate of the organic fouling of an anion exchange resin based upon total organic carbon measurements.
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. For a specific hazard statement, see Note 1.
