ISO 12696:2012
Cathodic protection of steel in concrete
ISO 12696:2011 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.
ISO 12696:2011 applies to steel embedded in atmospherically exposed, buried, immersed and tidal elements of buildings or structures.
