The use of fluid penetrants is particularly valuable in detecting discontinuities open to the surface, such as cracks, pores, and blowholes in nonmagnetic materials although it can be used on magnetic material if desired. The work to be tested is immersed in or coated with a fluid of low surface tension. Any surface opening or discontinuity will permit the entrance of the fluid. The excess fluid is removed from the surface and that which remains in the defect will then flow or creep and outline the defect.

CONT

Liquid penetrant test. A penetrant method of non-destructive testing used to locate defects open to the surface of nonporous materials; penetrating liquid is applied to the surface, and after 1-30 minutes excess liquid is removed, and a developer is applied to draw the penetrant out of defects, thus showing their location, shape, and size.

A liquid with low surface tension, usually containing a dye or fluorescent chemical; when flowed over a metal surface, it is used to determine the existence and extent of cracks and other discontinuities.

Key term(s)
  • dye penetrant

French

Domaine(s)
  • Contrôle destructif et non destructif (Matér.)
CONT

Ressuage (méthode de contrôle) (...) Méthode non destructive de contrôle des pièces métalliques basée sur la capillarité. [...] Une précision plus grande est obtenue en utilisant un liquide d'imprégnation fluorescent (colorant organique luminescent en solution dans de l'huile minérale). Après séchage, l'observation est effectuée dans l'obscurité, sous lumière noire (lampe de Wood). Les défauts apparaissent alors en brillant sur fond sombre et peuvent être photographiés. La méthode est applicable aux métaux ferreux et non ferreux.
