ASTM D5403-93(1998)

Standard Test Methods for Volatile Content of Radiation Curable Materials

SCOPE
1.1 These test methods cover procedures for the determination of weight percent volatile content of coatings, inks, and adhesives designed to be cured by exposure to ultraviolet light or to a beam of accelerated electrons.
1.2 Test Method A is applicable to radiation curable materials that are essentially 100% reactive but may contain traces (no more than 3%) of volatile materials as impurities or introduced by the inclusion of various additives.
1.3 Test Method B is applicable to all radiation curable materials but must be used for materials that contain volatile solvents intentionally introduced to control application viscosity and which are intended to be removed from the material prior to cure.
1.4 These test methods may not be applicable to radiation curable materials wherein the volatile material is water, and other procedures may be substituted by mutual consent of the producer and user.
1.5 This standard does not purport to address all of the safety problems, 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. A specific hazard statement is given in Note 9.
