This test procedure establishes a test method to determine whether corrosion products as a result of residual corrosive elements may be created on contact surfaces. Said products may be a result from improper cleaning or lack thereof@ improper processes@ entrapped particulates@ etc. The following plating systems (but not limited to) are of interest. ?? gold over copper (alloys) with or without nickel underplate@ ?? gold over palladium-nickel over copper (alloys) with or without nickel underplate@ ?? silver plated systems with or without underplates. This test procedure does not determine to what extent@ if any@ the performance of the product tested may be affected by the presence of residual corrosive elements on the contacts or connectors and any resulting corrosion from the test exposure. Any effect that the existence of residual corrosive elements may have on product performance would be dependent on many factors including the product design@ the location@ type@ concentration of residual corrosive elements@ and the actual application of the product.
