ASTM D2338-02(2013)

Standard Test Method for Determining Particle Size of Multicolor Lacquers (Withdrawn 2020)

SIGNIFICANCE AND USE
4.1 This test method provides a uniform nomenclature for the producer and user in the identification of the various particle sizes used in the manufacture of nitrocellulose-type multicolor lacquers.
SCOPE
1.1 This test method employs photographic reference standards to evaluate the particle size of multicolor lacquers.  
1.2 The values stated in SI units are to be regarded as 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WITHDRAWN RATIONALE
This test method employs photographic reference standards to evaluate the particle size of multicolor lacquers.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in December 2020. This standard is being withdrawn without replacement due to its limited use by industry.
