ASTM G192-08

1.1 This test method covers a procedure for conducting anodic polarization studies to determine the crevice repassivation potential for corrosion-resistant alloys. The concept of the repassivation potential is similar to that of the protection potential given in Reference Test Method G 5.

1.2 The test method consists in applying successively potentiodynamic, galvanostatic, and potentiostatic treatments for the initial formation and afterward repassivation of crevice corrosion.

1.3 This test method is a complement to Test Method G 61.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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.
