Besides of the penetrant test the surface crack test can also be conducted using the magnetic particle test. Therfore, the workpiece is magnetized while applying iron oxide powder, which orient towards the crack. Arising stray fields on surface defects indicate pores and cracks. The preparation and analysis of the test is solely conducted by certified personnel accoring to DIN EN 473 level 2.
Only for magnetizable materials and near-surface imperfections
Surface/crater crack: 100 and 104
Surface pores: 2011 - 2017
Near-surface lack of fusion: 401
Root concavity: 515 and 5013
