NACE SP21427-2023, Detection and Mitigation of Stray-Current Corrosion of Reinforced and Prestressed Concrete Structures

Available for download

This standard practice describes appropriate prevention and mitigation measures that can be applied to RC and PC structures that are, or can be, exposed to stray-currents from external sources in order to minimize or eliminate stray-current corrosion. This standard practice addresses only steel corrosion related issues, and does not deal with issues of safety and hazards to people or structures associated with DC and AC voltages; these are covered in national standards and regulations, such as EN 50443 and EN 50122-1.
