The coating is intended for use in environments that are not exposed to ultraviolet light. Its use may be restricted in some areas due to its coal tar content.

The purpose of this standard is to provide the means of detecting pinholes, flaws, or holidays in a coating system that may result in its premature failure, thereby possibly decreasing the life expectancy of the asset. This standard documents the equipment and the process of using electrical current to identify these holidays in a repeatable and realistic manner for both field and shop coating applications.
