CONTAINED IN VOL 06.03, 2005Specifies the determination of the easily hydrolyzable chloride content of liquid epoxy resins, defined as the reaction product of a chlorohydrin and a di- or polyfunctional phenolic compound. In both test methods the easily hydrolyzable chloride is saponified with potassium hydroxide. Method A then is directly titrated with hydrochloric acid and can be used for concentrations of 1 weight % and under. Method B is titrated potentiometrically with silver nitrate, and can be used for concentrations of 5 to 2500 ppm hydrolyzable chloride. Does not address all relevant safety issues, it is the users responsibility to establish suitable health and safety practices.
