This standard practice details a procedure for electrical detection of minute discontinuities in new coating systems that are applied to conductive substrates. There are two types of testing equipment covered: low-voltage wet sponge testers and high-voltage spark testers. Electrical testing to determine the presence and number of discontinuties in a coating is performed on a nonconductive coating applied to a conductive substrate.
