These test methods cover three procedures for determining the specific gravity of pigments, as follows: Test Method A which is for routine testing of several samples simultaneously, Test Method B which is for tests requiring greater accuracy than Test Method A, and Test Method C which is for rapid and accurate testing of single samples. 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. For Test Method A, the following apparatus and materials shall be used: pycnometer, water bath, manometer, desiccator, vacuum pumps, thermometer, weighing bottle, and immersion liquid. For Test Method B, the following apparatus and materials shall be used: pycnometer, water bath, manometer, vacuum pump, thermometer, weighing bottle, bell jar, and bottle. For Test Method C, the following apparatus and materials shall be used: buret, flask, stopcocks, vacuum pump, manometer, thermometer, weighing bottle, and immersion liquid.
This abstract is a brief summary of the referenced standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections , , and .
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
