SCOPE
1.1 This test method covers a procedure for the visual examination of any unpigmented liquid for use in paints and inks, including fatty oils and acids, drier solutions, solvents, miscellaneous chemicals, varnishes, resin solutions, clear lacquers, and other clear coatings for the presence or absence of undesirable components.
1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.>
WITHDRAWN RATIONALE
This test method covers a procedure for the visual examination of any unpigmented liquid for use in paints and inks, including fatty oils and acids, drier solutions, solvents, miscellaneous chemicals, varnishes, resin solutions, clear lacquers, and other clear coatings for the presence or absence of undesirable components.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.
