ASTM D2348-02

Standard Test Method for Arsenic in Paint (Withdrawn 2009)

SIGNIFICANCE AND USE
The permissible level of toxic elements in certain coatings is specified by governmental regulatory agencies. This test method provides a documented procedure for determining low concentrations of arsenic present in whole paint to determine compliance.
SCOPE
1.1 This test method covers the determination of less than 0.5 % arsenic in whole paint.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and 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WITHDRAWN RATIONALE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 less than 0.5 % arsenic in whole paint.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2009. This standard is being withdrawn without replacement due to its limited use by industry.
