本国际标准规定了钢铁（包括铸铁和铸铁）上黑色氧化物涂层的要求 熟铁、碳钢、低合金钢和不锈钢）。黑色氧化物涂层可用于减少 滑动面或支承面之间的摩擦，或用于装饰或减少光反射。这些涂层， 在需要黑色表面的情况下，无论是否进行辅助防腐处理，均可使用。只是非常 即使经过防腐处理，在轻度腐蚀条件下也能获得有限的防腐保护。 本国际标准未规定设备的条件、光洁度或表面粗糙度要求 黑色氧化前的基底。

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. Only very limited corrosion protection is obtained under mildly corrosive conditions even with preservative treatment. This International Standard does not specify requirements for the condition, finish or surface roughness of the substrate prior to black oxidizing.
