ASTM E 1220 - 99. Standard Test Method for Visible Penetrant Examination Using Solvent-Removable Process

American Society for Testing and Materials (ASTM). 1999, 6 pages.
This test method2 covers procedures for visible penetrant examination utilizing the solvent-removable process. It is a nondestructive testing method for detecting discontinuities
that are open to the surface such as cracks, seams, laps, cold shuts, laminations, isolated porosity, through leaks, or lack of fusion and is applicable to in-process, final, and maintenance
examination. It can be effectively used in the examination of nonporous, metallic materials, both ferrous and nonferrous, and of nonmetallic materials such as glazed or fully densified
ceramics and certain nonporous plastics and glass.
