Scope and Limitations

The provisions of this standard should be applied under the direction of a registered Professional Engineer or a person certified by NACE International as a Corrosion Specialist or a CP Specialist. The person's professional experience should include suitable experience in CP of reinforced concrete structures. Under certain circumstances, a CP system may either become a structural component or significantly affect the serviceability and structural performance of a reinforced concrete structure; therefore, such impact by the CP system should be reviewed by a qualified registered Structural Engineer or the equivalent.

The guidelines presented here are limited to CP systems for new or existing buried or submerged reinforced concrete elements.

When the reinforcing steel is bonded to facility grounding, as commonly required by the National Electrical Code, the resulting galvanic corrosion cell and the possible adverse affects on the quantity and distribution of CP current to the reinforcing steel shall be considered.
