This specification covers the requirements, procedures, and accept/reject criteria for inspecting ground chromium plated surfaces for grinder-induced damage to the chromium plate and substructure. The apecification also provides users with criteria for distinguishing between such damage and acceptable indications inherent to the chromium plate.

This procedure is used for nondestructive testing of heat treated, high strength, (180 ksi (1240 MPa) or higher tensile strength), low-alloy steel parts which have ben chromium plated and subsequently ground, but usage is not limited to such applications.
