1.1 This test method covers the determination of the relative solvent power of hydrocarbon solvents used in paint and lacquer formulations. This test method is suitable for use with solvents having an initial boiling point over 40°C and a dry point under 300°C when determined in accordance with the procedures in Note 1.

Note 1—Test Method D-86 is used to determine the initial boiling point and dry point for mineral spirits and similar petroleum solvents. Test Method D-1078 is used for pure compounds and narrow boiling range cuts.
