Material Factors in Relation to Development Time in Liquid-Penetrant Inspection. Part 1. Material Factors

Abstract

In technical publications and European Standards the development time (i.e. time of getting out of penetrant from a discontinuity to the material surface) in penetration testing is specified within the range of 10-30 minutes. In practice, however, it is seen , that it is closely connected
