1.1 This International Standard specifies a rapid and accurate method for evaluating the corrosion resistance characteristics of copper-nickel-chromium and nickel-chromium electrodeposits on steel or zinc-base die castings designed for outdoor service. It does not prescribe exposure periods to be used for a specific product, nor the interpretation to be given to the results. 1.2 The suitability of this test and correlation of results with outdoor service experience should be determined before it is specified for coating systems or materials other than those described in 1.1. 1.3 Test conditions are provided[1] to electrolytically dissolve the underlying coatings of nickel through discontinuities in the chromium overlay (whilst not attacking the chromium) at such a rate that electrolysis for 2 min produces about the same extent of corrosion as does 1 year of service[2][3]. The same acceleration of corrosion in the EC test over the rate in outdoor service is maintained on specimens where the exposed nickel area increases rapidly (such as on those with high discontinuity density) by changing from constant potential control to constant current control when a predetermined current density is attained on the specimen surface.
