The designation DIN 50961 Fe/Zn 8b describes a specific electroplated zinc coating on steel (or iron) parts. The standard (DIN 50961, now largely superseded by DIN EN ISO 4041 but still widely used in industry) defines the coating thickness, corrosion resistance requirements, and post-treatment (chromating).
: The German standard for electroplated zinc coatings on iron materials. It is now primarily used in conjunction with DIN EN ISO 2081 : Indicates the base material is iron or steel : Specifies a minimum zinc coating thickness of 8 micrometers ( : Denotes the type of chromate conversion coating (passivation).
