Abstract:

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.

Scope:

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

Test Method AFor Routine Testing of Several Samples Simultaneously.

Test Method BFor Tests Requiring Greater Accuracy than Test Method A.

Test Method CFor 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.
