Abstract
A method for detecting surface defects in parts by entrapped fluorescent dye penetrant uses a novel applicator which conveys liquid fluorescent dye penetrant by capillary action from a reservoir within the applicator to the surface of the object being tested. The liquid fluorescent dye penetrant has low viscosity and high penetrating power which make the method and applicator effective in detecting minute surface flaws.
