Description of ASTM-D387 2008ASTM D387 - 00(2008)Standard Test Method for Color and Strength of Chromatic Pigments with a Mechanical MullerActive Standard ASTM D387 | Developed by Subcommittee: D01.26 Book of Standards Volume: 06.01 ASTM D387Significance and Use Color and tinting strength are the most important properties of a color pigment. This test method provides a means of testing these properties for quality control. This test method is intended as a referee method so that such matters as the vehicle for preparing the dispersions and the white for making tints have been suggested. However, other vehicles and whites may be suitable for quality control purposes, and changes in this test method are allowed by agreement between the parties to a test. It is assumed that the most exact comparison of mass color and tinting strength occurs when the pigment is completely dispersed. By following the procedure described in Annex A1, the conditions for achieving the maximum practical degree of dispersion with a mechanical muller may be determined. Color and strength tests should be carried out under these conditions. The results obtained with a mechanical muller do not necessarily correlate directly with an industrial situation where different dispersing conditions exist. However, dispersion with a mechanical muller is a quick and inexpensive way of testing the color and strength of a pigment for routine quality control. 1. Scope 1.1 This test method is intended to be used to compare the color and strength of a pigment under test with a reference standard of the same type and grade. 1.2 This test method does not apply to white pigments. Note 1Test Method D 3022 is similar to this test method, but it utilizes a miniature sandmill rather than a mechanical muller, to disperse the chromatic pigment. Note 2Test Method D 332 and Test Method D 2745 are similar to this test method, but they are intended for use with white pigments, rather than chromatic pigments. 1.3 The values stated in SI units are the preferred unit of measurement. 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. Specific hazard statements are given in Section 8.
