Description

ASTM G69-12

Historical Standard: Standard Test Method for Measurement of Corrosion Potentials of Aluminum Alloys

ASTM G69

Scope

1.1 This test method covers a procedure for measurement of the corrosion potential (see Note 1) of an aluminum alloy in an aqueous solution of sodium chloride with enough hydrogen peroxide added to provide an ample supply of cathodic reactant.

Note 1—The corrosion potential is sometimes referred to as the open-circuit solution or rest potential. See Practice G193.

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.
