Cathodic Protection of Reinforcing Steel in Buried or Submerged Concrete Structures
|Publication Date:||26 June 2014|
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 as a Corrosion Specialist or a CP Specialist. The person's professional experience shall include suitable experience in CP of conventionally reinforced and prestressed 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 in this standard are limited to CP systems for new or existing buried or submerged reinforced concrete elements.
When the reinforcing steel is bonded to the facility's grounding, as is commonly required by the National Fire Protection Association's(1) (NFPA) NFPA 70, National Electrical Code,8 the resulting galvanic corrosion cell and the possible adverse effects on the quantity and distribution of CP current to the reinforcing steel shall be considered.
