DYE PENETRANT INSPECTION
PENETRANT INSPECTION (DPI/PT)

Dye Penetrant Inspection (DPI) is generally carried out on non-ferrous materials such as stainless steel and aluminum to detect surface breaking discontinuities or cracks by the use of dyes and developers.

The procedure begins with the application of a dye to the part to be inspected which is then left to dwell for a set amount of time before being washed away with water, or a solvent, and then left to dry. Once this is done a developer is applied, and with capillary action, the dye is drawn out of discontinuities leaving visible indications on the surface.
