ASTM D3741-00

Standard Test Methods for Appearance of Admixtures Containing Halogenated Organic Solvents

SCOPE
1.1 This test method covers the visual determination of the physical appearance of admixtures containing halogenated hydrocarbons. It is a qualitative test method.
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 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
