This test method covers the procedures for testing the package stability of liquid paint by determining the change in consistency and certain other properties of the solvent- or water-reducible type paint when stored above a certain temperature. Test equipment include spatula, viscometer, paint brush, and test surface. Samples for testing should be collected from as received and stored samples. The samples must be observed for any skinning, corrosion, odor of putrefaction, rancidity, or souring, lower layer rigidity, consistency, and the presence of lump or streaks in the brushed films.

1.1 This test method covers the change in consistency and certain other properties that may take place when liquid paint of either the solvent-reducible or water-reducible type is stored at a temperature above 0°C (32°F).
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
