ASTM E1208 : 10

Standard Practice for Fluorescent Liquid Penetrant Testing Using the Lipophilic Post-Emulsification Process

Standard Details

Liquid penetrant examination methods indicate the presence, location, and, to a limited extent, the nature and magnitude of the detected discontinuities. This practice is normally used for production examination of critical components or structures when (a) removal of excessive amounts of penetrant from discontinuities using a water-washable process can be a problem and (b) the use of a hydrophilic remover is impractical.
