Liquid Penetrant Testing Level I


Arrelic define Dye penetrant inspection (DPI), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials such as metals, plastics, or ceramics. The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. It is also called liquid penetrant inspection (LPI) or penetrant testing (PT). is based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed and a developer is applied.

PT Level-I Responsibility:

An individual certified to Penetrant Level 1 has to demonstrate competence to carry out NDT according to written instructions and under the supervision of Level 2 or Level 3 personnel.

  • Set up Penetrant Testing equipment;
  • Perform the Penetrant Inspection tests;
  • Record and classify the results of the tests according to written criteria;
  • Report the results
