This method of checking is fast, inexpensive and performed with great accuracy. The penetration of the liquid inside a discontinuity occurs by capillarity and not by gravity; this prerogative, is the basis of the entire control methodology, makes it easy to inspect surfaces that are difficult to access regardless of their position. The ability of a liquid to penetrate into surface cavities essentially depends on: Cavity configuration Surface tension Wetting power However, for a correct understanding of the method, three fundamental terms must be defined: Indication - highlights the presence of a discontinuity in the material. Some claims may be irrelevant or false. Discontinuity - a break in the normal physical structure or configuration of the surface, such as a crack, a forging fold, a draw line, an inclusion or porosity. The presence of a discontinuity does not necessarily exclude the use of the part. Defect - a discontinuity deemed "unacceptable" by the specifications in which one operates.
