鋼鍛件的無損檢驗 第1部分:磁粉探傷 EN 10228-1 - 1999

　　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.
