Liquid Penetrant Testing (PT)
Liquid penetrant testing (PT) is a sensitive nondestructive testing method for detecting and locating discontinuities which are open to the surface. The NDT method employs a penetrating liquid dye which is applied to the properly cleaned surface to be examined and which enters the discontinuity by capillary action. After a suitable period of time has passed, the excess penetrant is carefully removed from the surface and the part is dried. A developer is then applied which acts as a blotter, drawing the penetrant out of the discontinuity. The penetrant, drawn from an opening on the surface, indicates the presence and location of a discontinuity.
