The two penetrant types are either fluorescent or color contrast (dye) penetrant. Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries. NDT Training, Qualification, Certification, Procedure Approval & Inspection Services.

All dye products caused a similar dose-dependent reduction in percentage of adult emergence. After rinsing, the part is again dried, perhaps with a lint-free paper towel, or maybe oven-dried. The dry developer is not suitable for visible penetrant as the developer does not provide a contrasting background. It is highly sensitivity (small discontinuities can be detected). (c) The surface is wiped with a clean textile and subsequently remover spray is applied to remove excess residues on the surface and wait for a few min. Paint must be removed from areas to be tested. The difference is the hydrophilic emulsifier method requires a water-based remover solution; hence, removing the excess surface penetrant occurs using a detergent action rather than an emulsification action. These, too, will grow and spread if the defect is large or extensive. The penetrant method and sensitivity level are determined. The procedure for a dye penetrant test relies on the principle of capillary action, which describes how fluids penetrate into cracks (or discontinuities) on the surface of a material. Session, Identifies the user and allows authentication to the serverExpiration: The maximum development time is in place to minimize excessive penetrant bleed out from an indication that could potentially obscure the indication. Lipophilic emulsifier application occurs to transfer the excess penetrant on the surface of the tested piece to an emulsifiable mixture that can be washed with water. Coat the part or section to be inspected with Cleaner/Remover. non-aqueous wet, Visibility varied with dose and dye product; 1 g/liter dye was less visible than 2, 3, or 4 g/liter, and Stella green had lower visibility than other dyes.
