ASTM D2349-90(2003)

Standard Test Method for Qualitative Determination of Nature of Solvent Composition in Solvent-Reducible Paints

SIGNIFICANCE AND USE
This test method provides a procedure for determining qualitatively the composition of solvent in paints containing only hydrocarbon solvents.
SCOPE
1.1 This test method covers the determination of the nature of solvent in solvent-reducible house paints containing only hydrocarbon solvents.
1.2 This standard does not purport to address 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.
