ASTM D1647-89(1996)e1

Standard Test Methods for Resistance of Dried Films of Varnishes to Water and Alkali (Withdrawn 2004)

SCOPE
1.1 These test methods cover the determination of the resistance of dried varnish films to immersion in water and dilute alkali at room temperature.  
1.2 The values stated in inch-pound 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.
WITHDRAWN RATIONALE
These test methods cover the determination of the resistance of dried varnish films to immersion in water and dilute alkali at room temperature.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in December 2004 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by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.
