ASTM D2074-92(1998)

Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines by Alternative Indicator Method (Withdrawn 2007)

SCOPE
1.1 These alternative test methods cover the indicator procedure for determining the total, primary, secondary, and tertiary amine values of fatty amines. These procedures are not applicable to fatty amidoamines and fatty diamines.  
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WITHDRAWN RATIONALE
These alternative test methods cover the indicator procedure for determining the total, primary, secondary, and tertiary amine values of fatty amines. These procedures are not applicable to fatty amidoamines and fatty diamines.
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the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.
