1. Range: 1.1 This method includes the determination of the corrosion resistance of decorative chrome plating using the Corrodkote method ~ 2. This method is mainly used for copper-nickel-chromium or nickel-chromium-plated pieces. 2. Method Overview 2.1 The test is to apply a paste containing a corrosive salt to the test piece; the test piece is allowed to dry, and the test piece coated with the paste is exposed to high relative humidity for a specified period of time. 3. Equipment 3.1 Equipment Including hot chamber, specimen holder, hot chamber heating equipment, and hot chamber air circulation equipment. 3.2 The hot water chamber in the roof or cover, or specimen rack accumulation of water droplets shall not fall on the test piece. NOTE 1 - Appropriate equipment may be modified by a salt spray box, modified by removing the salt spray nozzle,
