Penetration Test (PT)

The penetration test according to ISO 3452 specifies a procedure for finding defects such as cracks, overlaps, folds, pores and lack of fusion, which open towards the surface of the material to be checked. In this non-destructive test, the component is cleaned and then immersed in or sprayed with a penetrant. The penetrant remains in the imperfections after rinsing. The product defects are then made visible after developing and drying with the aid of UV light. With this test process we discover defects that could lead to the failure of the component.
