(Test Method)Standard Test Method for Package Stability of Paint
Standard Test Method for Package Stability of Paint
ABSTRACT
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.
SCOPE
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.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

4. Procedure
4.1 Obtain duplicate samples of the paint in original, unopened containers in accordance with Practice D3925 (Note 1). If a long
term test calls for intermediate examinations, obtain an additional duplicate sample for each intermediate examination as agreed
upon between laboratories or buyer and seller. Examine one of the samples received for the characteristics listed in 4.2, using the
procedures therein described. Weigh the other unopened samplesamples to the nearest 1 g, then hold itthem undisturbed for
specified periods of time and ranges of temperature, as agreed upon between purchaser and seller (Note 2). After storage, reweigh
the samplesamples without shaking to determine any loss of weight resulting from faulty closure.
NOTE 1—Containers should preferably be no larger than 1 L (1 qt).
NOTE 2—Storage for 1 month at 52 6 1°C (125 6 2°F) simulates some of the effects of storage for 6 months to 1 year at 23 6 2°C (73 6 3.5°F).
However, it should be recognized that storage at 125°F may not simply accelerate changes occurring at 73°F. With water-borne paints, for example, at
125°F the growth of some putrefying bacteria is inhibited.
