Penetrant Inspection Standards

Source

The purpose of this paper is to review some of the quantitative techniques that have been used for the evaluation of penetrant systems and to present an analysis technique based on analysis of variance (ANOVA) that appears to have a potential for rating penetrants.

The paper covers five areas: quantitative penetrant methods, two-fold congruency evaluation, the limitations on the reuse of the specimens, the influence of threshold visibility on evaluation of penetrants, and crack line intersection counting and evaluation of the crack line intersection data by ANOVA to evaluate the effects of primary and secondary influencing variables.
