Penetrant Testing (PT) also called Dye Penetrant Inspection (DPI) or Liquid Penetrant Inspection (LPI) is a fast, portable and sensitive non-destructive testing method that allows the inspection of a large variety of materials, components, and systems for discontinuities that are open to the surface, and often in remote locations. These discontinuities are made visible by a penetrant liquid that seeps into and out of a surface discontinuity.
