1.1 Electrical testing to determine the presence and number of discontinuities in a coating film is performed on a nonconductive coating applied to a conductive surface. The allowable number of discontinuities should be determined prior to conducting this test since the acceptable amount of discontinuities will vary depending on coating film thickness, design, and service conditions.

1.2 This recommended practice is not intended to provide data on service life, adhesion, or film thickness of an applied system.

1.3 To prevent damage to a coating film when using high voltage test instrumentation, total film thickness and dielectric strength in a coating system shall be considered in selecting the appropriate voltage for detection of discontinuities.
