Inspection is carried out below ultraviolet or white mild, relying on the kind of dye used – fluorescent or nonfluorescent (seen). The penetrant could also be utilized to all non-ferrous supplies and ferrous supplies, though for ferrous elements, magnetic-particle inspection is usually used as an alternative for its subsurface detection functionality.
