ASTM D153-84(2014)

1.1 These test methods cover three procedures for determining the specific gravity of pigments, as follows:

Test Method A-For Routine Testing of Several Samples Simultaneously.

Test Method B-For Tests Requiring Greater Accuracy than Test Method A.

Test Method C-For Rapid and Accurate Testing of Single Samples.

1.2 The specific gravity value obtained by these procedures may be used with the weight of a dry pigment to determine the volume occupied by the pigment in a coating formulation.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 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. For specific hazard statements, see Sections 5, 11, and 15.
