Standard Test Method for Stability of Perchloroethylene with Copper

SIGNIFICANCE AND USE
This test method is to be used as a guide in selecting or eliminating certain grades of perchloroethylene used for drycleaning fabrics or degreasing metal parts.
SCOPE
1.1 This test method covers the evaluation of the corrosiveness to copper metal by perchloroethylene.
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.
