(normative)
Microscopic examination of rail steels using standard diagrams to
assess the content of non-metallic inclusions
F.1 General
F.1.1 Degree of purity
The degree of purity (index K3) is a value indicating the content of non-metallic inclusions in the form of oxides
inclusions in the product. The K3 index is a value indicating the content of such oxides by the determination of
the percentage area of non-metallic inclusions in the structure, i.e. the sum obtained by counting inclusions
weighted according to their area, starting from a specified size of inclusion upwards, and referred to an area of
1 000 mm².
