This standard covers the requirements for both one and two side pure zinc and zinc nickel alloy electrogalvanized coatings. These coatings are applied to a sheet steel substrate utilizing an electroplating process. The sheet steel substrate may be either cold or hot rolled low carbon, rephosphorized, solid solution strengthened, bakehardenable, high strength low alloy, dual phase, complex phase, or martensitic sheet steel. Additional requirements or agreements shall be specified by regional GM Automotive Operations (GM) business units [e.g., North America (GMNA), Europe (GME), Latin America (GMLAAM), and Asia Pacific (GMAP)].
