ABSTRACT:
A solvent-remover composition and process in which a glycol liquid or water containing an alcohol or glycol-ether accelerator solvent is used as a solvent to remove surface penetrant from test parts in the so-called solvent-remover inspection penetrant process. The remover solvents of the invention provide inhibited solvency for oily water-insoluble dyed penetrant liquids, thus preventing excessively rapid depletion of entrapments in surface cracks. The flaw detection capability of the solvent-remover penetrant process is thereby improved.
