(Test Method)Standard Test Method for Metal Corrosion by Halogenated Organic Solvents and Their Admixtures
Standard Test Method for Metal Corrosion by Halogenated Organic Solvents and Their Admixtures
SIGNIFICANCE AND USE
These tests are to be used as a guide in selecting or eliminating certain solvents or grades of solvents used for cleaning or degreasing metal parts.
SCOPE
1.1 This test method covers the evaluation of the corrosiveness to metals by halogenated organic solvents and their admixtures for cold cleaning applications.
Note 1—The test method described herein is an adaptation of Test Method D130.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
