1.1 This test method covers determination of the solubility of resins and polymers in terms of the region of solubility parameter and hydrogen bonding of solvents in which complete solution occurs. In some cases dipole moment of the solvents may also be required to delineate more exactly the boundaries of solubility.
1.2 This test method is applicable only if the test solutions are of sufficient clarity and freedom from color to allow accurate visual judgement of complete solubility and of low enough viscosity for solution to take place.
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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement see Note 1 in 6.2.
