ISO 24284:2022 pdf download, Metallic coatings — Corrosion test method for decorative chrome plating under a de-icing salt environment.
ISO 24284 specifies the apparatus, reagents, and procedure to assess the corrosion resistance of chromium electroplated parts in the presence of de-icing salts (especially calcium chloride) in the laboratory.
ISO 24284 is primarily applicable to decorative parts plated with chromium, especially to exterior (automobile) parts electroplated with nickel-chromium or copper-nickel-chromium.
ISO 24284 simulates a special corrosion in the presence of hygroscopic and corrosive de-icing salt and conductive mud with a high salt concentration on chromium electroplated deposits during winter.
