Principle of Dye Penetrant Test (DPI)

Dye Penetrant is drawn into the surface-breaking crack by capillary action and excess surface penetrant is then removed; a dry powder is then applied to the surface, to draw out the penetrant in the crack and produce a surface indication. The indications produced are much broader than the actual flaw and are therefore more easily visible.
