Standard Test Method for Color and Strength of Color Pigments by Use of a Miniature Sandmill (Withdrawn 2020)

SIGNIFICANCE AND USE
This test method is a way of testing the color and strength of pigments by use of a miniature sandmill. It correlates well with industrial practice and is used for routine quality control.
SCOPE
1.1 This test method covers the determination, through the use of a miniature sandmill, of the color and strength of dry color pigments.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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 Section 6.
WITHDRAWN RATIONALE
This test method covers the determination, through the use of a miniature sandmill, of the color and strength of dry color pigments.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in January 2020 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
