Aerospace series. Metallic materials. Micrographic determination of content of non-metallic inclusions1 Scope This document specifies the general requirements for the micrographic determination of content of non metallic inclusions of metallic materials for aerospace applications. It also gives tables of standard acceptance criteria for particular steel types. It shall be applied when referred to in the EN technical specification or material standard unless otherwise specified on the drawing, order or inspection schedule. This document is mainly
