DYE PENETRANT (PT) TESTING


The dye penetrant method of inspection is a non-destructive test for defects open to the surface.  It may be used on materials such as aluminum, magnesium, brass, copper, cast iron, steel, stainless steel, carbides, stellite, certain plastics, and ceramics. 
Surfaces will need to be free of foreign materials and paint (grease, oils, etc.).  Foreign materials prevent penetrant and hinder removal, therefore wire brushing or similar pre-cleaning is necessary.  Paint must be removed from areas to be tested. 

​The basics of this method are: 
1.  Cleaning the part or section to be inspected with cleaner/remover.
2.  Applying the penetrant with spray can or brush to the section/part needing to be inspected.
3.  Removal of the penetrant with cloths pre-moistened with the cleaner/remover
4.  Applying the developer with a spray can.
5.  Development of a defect will show up deep red during the final inspection.
