Meaning and Purpose
4.1 Test Method A is a direct method using readily available laboratory equipment and glassware. Test method A can only be used with powders that do not contain metallic pigments.

4.2 Test Method B provides better precision at a higher cost and includes metals, although different models yield different overall averages for each of the three samples tested.

4.3 Test method C can be used when the recipe is known and the density of each ingredient is available.

ASTM D 5965-2019 Density of Powder Coatings

Scope of
1.1 These standard test methods cover three procedures for determining powder density of coatings, as follows:

1.2 Test Method A, for testing coated powders, excluding metals, is a method using off-the-shelf laboratory equipment (e.g., analytical balances, volumetric flasks, etc.).

1.3 Test Method B requires the use of specific gravity bottles.

1.4 Test Method C is a method for calculating powder density based on formulation components and their quantities and densities.

1.5 Values expressed in SI units should be considered standard. The values given in parentheses are for reference only.

1.6 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.

1.7 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.
