Abstract

Specifies a rapid and accurate method for evaluating the corrosion resistance characteristics of electrodeposits on steel or zinc-base die casting designed for outdoor service. Does not describe exposure periods to be used for a specific product, nor the interpretaiton to be given to the results. Test conditions are provided to electrolytically dissolve the underlying coatings of nickel through discontinuities in the chromium overlay at such a rate that electrolysis for 2 min produces about the same extent of corrosion as does 1 year of service.
