ASTM D7540-09(2013)

5.1 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 to prepare specimens for testing the color and strength of a pigment for routine quality control.

5.2 By following the procedure described in 1.1 This practice is intended to be used to disperse a chromatic pigment for subsequent testing.

1.2 This practice does not apply to white pigments.

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.
