1 Scope
This document specifies performance requirements for cathodic protection of steel
in cement-based concrete, in both new and existing structures. It covers building
and civil engineering structures, including normal reinforcement and prestressed reinforcement
embedded in the concrete. It is applicable to uncoated steel reinforcement and to
organic-coated steel reinforcement.
This document applies to steel embedded in atmospherically exposed, buried, immersed
and tidal elements of buildings or structures.
NOTE 1
Annex A gives guidance on the principles of cathodic protection and its application to steel
in concrete.
NOTE 2 This document, while not specifically intended to address cathodic protection of steel
in any electrolyte except concrete, can be applied to cathodic protection of steel
in other cementitious materials such as are found, for example, in early 20th century
steel-framed masonry, brick and terracotta clad buildings. In such applications, additional
considerations specific to these structures are required in respect of design, materials
and installation of cathodic protection; however, the requirements of this document
can be applied to these systems.
