Overview
The test method covers procedures for testing the stability of liquid paint packaging by determining changes in consistency and certain other properties of solvent-based or water-based paint when stored above a certain temperature. Test equipment includes scraper, viscometer, paint brush and test surface. Test samples should be collected from received and stored samples. It is necessary to observe the sample for any crusting, corrosion, spoilage odor, rency or sour taste, stiffness of the underlying layer, consistency and the presence of clumps or streaks in the drawn film.

Scope of
1.1 This test method covers changes in consistency and certain other properties that may occur when solvent reducible or water-based liquid coatings are stored at temperatures higher than 0°C (32°F).

1.2 Values expressed in SI units shall be regarded as standards. The values given in parentheses are for reference only.

1.3 This standard is not intended to address all safety issues, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.

1.4 This international Standard has been developed in accordance with the internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the Committee on Technical Barriers to Trade of the World Trade Organization.
