Chemical conversion coatings. Black oxide coating on iron and steel. Specification and test methods Ingestion-build-50790 This European Standard applies to1 Scope This International Standard specifies requirements for black oxide coatings on iron and steel (including cast and wrought iron, carbon steel, low alloyed steel and stainless steel). Black oxide coatings can be used to diminish friction between sliding or bearing surfaces or for decorative purposes or to reduce light reflection. Such coatings, with or without supplementary preservative treatment, may be used where a black surface is required.
