ASTM D2079-92(1998)

Standard Test Method for Nonvolatile Matter (Solids) in Fatty Quaternary Ammonium Chlorides (Withdrawn 2007)

SCOPE
1.1 This method covers the determination of nonvolatile matter (solids) in fatty quaternary ammonium chlorides.
1.2 This standard does not purport to address all of the safety problems, 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.>
WITHDRAWN RATIONALE
This test method covers the determination of nonvolatile matter (solids) in fatty quaternary ammonium chlorides.
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the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.
