Scope

This standard specifies the technical requirements for cathodic protection of reinforcing bars in new and existing concrete structures, and is applicable to reinforcing bars, prestressed reinforcing bars, as well as uncoated reinforcing bars and reinforcing bars with organic coatings in concrete structures.
This standard is applicable to steel in buildings and structures exposed to the atmosphere, buried in the ground, underwater, and in tidal environments.
Note 1: Appendix A introduces the principle of cathodic protection and its application in reinforcing bars for concrete.
Note 2: This standard is not applicable to the cathodic protection of reinforcing bars in non-concrete electrolytes, but is applicable to the cathodic protection of reinforcing bars in cement-based materials. For example, steel-framed masonry, brick, and clay composite structures from the early 20th century. This standard is applicable to such structures, but special consideration needs to be given to the design, materials, and installation of cathodic protection.
