Defines two micrographic procedures for determination of the non-metallic inclusion content of cast steels. Defines numerical values of the area fraction of non-metallic inclusions present in samples of cast steels.

This British Standard specifies two micrographic methods for determining the non-metallic inclusion content of cast steels. Numerical values of the area fraction of non-metallic inclusions present in samples of cast steels is specified.

The percentage content ranges of non-metallic inclusions are specified for four melting and refining methods in use in steel foundries throughout the UK.

In addition to the definitive requirements, this standard also requires the items detailed in clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.
