HISTORICAL DOCUMENT. ANSI APPROVED. Addresses applications for cathodic protection (CP) coupons attached to buried pipelines to determine the level of corrosion protection provided by a CP system. Appendixes cover coupons attached to other structures such as underground storage tanks (USTs), aboveground (on-grade) storage tank bottoms, and steel in reinforced concrete structures. CP coupons may also be used to evaluate compliance with CP criteria, including considering the IR drop. Key words: cathodic protection, coupons, underground storage tanks, aboveground storage tank bottoms.
Standard for achieving effective control of external corrosion on buried or submerged metallic piping systems or other buried metallic structures. System design. Coatings. Cathodic protection criteria & installation. Control of interference currents.
