ASTM D5627-17

Standard Test Method for Water Extractable Residue from Particulate Ion-Exchange Resins

SIGNIFICANCE AND USE
5.1 The presence of water extractables in ion-exchange resins can cause fouling of other materials downstream and contamination of process water. The quantity of water extractables is sometimes used as a specification to indicate resin quality, and typical values are 0.01 to 0.1 %.  
5.2 It is recognized that this test method may not remove all potential sloughage products and does not measure volatile compounds. More extensive extraction and identification of compounds may be needed in specific cases.
SCOPE
1.1 This test method covers the measurement of water soluble extractable residue from particulate ion-exchange resins based on elevated temperature extraction and gravimetric determination of residue.  
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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
