Significance and Use

Nickel/chromium and copper/nickel/chromium electrodeposited coatings are widely used for decorative and protective applications. The Corrodkote test provides a method of controlling the quality of electroplated articles and is suitable for manufacturing control, as well as research and development.

1. Scope

1.1 This test method covers the Corrodkote method of evaluating the corrosion performance of copper/nickel/chromium and nickel/chromium coatings electrodeposited on steel, zinc alloys, aluminum alloys, plastics and other substrates.

Note 1The following ASTM standards are not requirements. They are reference for information only: Practice B 537 , Specification B 456 , Test Method B 602 , and Specification B 604 .

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.
