ASTM-D4301 › Standard Test Method for Total Chlorine in Epoxy Resins and Compounds
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method describes a procedure for the determination of total chlorine in epoxy resins and glycidyl ethers.
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 specific hazard statements, see Section 8.
Significance and Use
The presence of residual chlorine in epoxy resins is deleterious to final product properties. This test method has been found to be applicable to resins or ethers with chlorine contents ranging from 50 ppm to 35 % by weight. Other halogen compounds react with the reagent but are distinguished from chlorine by the final potentiometric titration. Epoxy and other functional groups will consume reagent but do not affect the results.
