本SAE标准涵盖了由压铸锌合金（SAE J468合金903和925）和锻造锌带（ASTM B 69）制成的外部装饰件上电沉积铜、镍和铬的物理和性能要求。这种类型的涂层旨在为汽车、卡车、船舶和农场使用提供高度的耐腐蚀性，这些地方需要明亮的装饰性饰面。

This SAE Standard covers the physical and performance requirements for electrodeposited copper, nickel, and chromium deposits on exterior ornamentation fabricated from die cast zinc alloys (SAE J468 alloys 903 and 925), and wrought zinc strip (ASTM B 69). This type of coating is designed to provide a high degree of corrosion resistance for automotive, truck, marine, and farm usage where a bright, decorative finish is desired.
