These test methods cover the determination of the total chlorine content, in concentrations below 1 weight percent, of epoxy resins. Both organic and inorganic chlorine compounds contained in the resin are determined. Epoxy resin is defined as the reaction product of a chlorohydrin and a di- or polyfunctional phenolic compound.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
