DIN 53099 published
DIN 53099 "Metallic coatings - Electroplated chromium coatings from chromium(III)-based electrolytes on copper-nickel coatings on plastics - Requirements and test methods" has been published with issue date 2024-12.
The document "Metallic coatings - Electroplated chromium coatings from chromium(III)-based electrolytes on copper-nickel coatings on plastics - Requirements and test methods" specifies requirements for corrosion-protective, decorative-functional, electroplated chromium coatings from chromium(III)-based electrolytes on nickel and copper-nickel coatings on plastics as well as corresponding test methods. For electroplated nickel-chromium and copper-nickel-chromium coatings on plastics in which the chromium coatings are deposited from chromium(VI)-based electrolytes, see DIN 53100. For electroplated nickel-chromium and copper-nickel-chromium coatings with chromium coatings from chromium(VI)-based electrolytes on metals, see DIN EN ISO 1456.
For the deposition of chromium coatings from chromium(III)-based electrolytes on metals, the information in this document is applicable mutatis mutandis. It is not applicable to electroplated coatings deposited on plastics for technical purposes. The document can be obtained from DIN Media GmbH, 10772 Berlin (address: Am DIN-Platz, Burggrafenstraße 6, 10787 Berlin), according to the ZVO.
