Dye Penetrant Testing

SNT Level II | III PT Technicians Provider  

Dye Penetrant Inspection, also known as Penetrant Testing (PT), Liquid Penetrant Inspection (LPI) or Fluorescent Penetrant Inspection (FPI).


Liquid penetrant is applied to the surface and left to soak, being drawn into any cracks by capillary action. Excess penetrant is then removed and a developer applied to draw out the penetrant from cracks, to enable a visual inspection of any defects. Accurate interpretation is achieved by utilizing our seasoned NDT qualified Penetrant Testing Inspectors.


Dye Penetrant Inspection can be used on almost any non-porous material.


The types of defects that can be found with penetrant testing are:

  • Rolled Products: Penetrant identifies anomalies (cracks, seams or laminations)

  • Castings: cold shuts, hot tears, porosity, blow holes or shrinkage

  • Forgings: Illuminating cracks, laps or external bursts

  • Welds: To identify cracks, porosity, undercut, overlap, lack of fusion or lack of penetration


We have available more than 45 NDT technicians qualified to SNT Level II in Penetrant Testing (PT) in compliance with SNT-TC-1A. As a minimum, all JCI penetrant testing inspection engineers have more than one NDT qualification.
