ASTM D2348-91(1996)

Standard Test Method for Arsenic in Paint

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.
