Non-destructive testing of steel forgings: Part 1 - Magnetic particle inspection (BS EN 10228 1:1999) describes the method and acceptance criteria to be used for the magnetic particle inspection of forgings manufactured from ferromagnetic materials. The method described is used for the detection of surface discontinuities. | Non-destructive testing of steel forgings-Part 1 Magnetic particle inspection BS EN 10228-1 1999 1 Scope This part of EN 10228 describes the method and acceptance criteria to be used for the magnetic particle inspection of forgings manufactured from ferromagnetic materials. The method described is used for the detection of surface discontinuities. It can also detect discontinuities just below the surface but sensitivity to such discontinuities diminishes rapidly with depth. 2 Normative references This part of EN 10228 incorporates by dated or undated reference provisions from other publications.
