The penetrant is a liquid that has two characteristics â the ability to enter fine cracks and some type of dye to make the cracks visible. This dye can be either an intense red or reddish-purple dye, or a dye that fluoresces when exposed to ultraviolet light. The type of dye depends on the type of inspection. During an inspection, the penetrant is applied to the surface of the part to be inspected. If there are any surface flaws, the penetrant enters them, as illustrated in Figure 1. The second step involves removing the excess surface penetrant from the part, leaving penetrant in any surface flaw illustrated in Figure 2.
