Anotace

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.
