Protection against corrosion by stray current from direct current systems1 Scope This standard establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (d. c.) on buried or immersed metal structures. The standard is intended to offer guidance for: the design of direct current systems which may produce stray currents; the design of metal structures, which are to be buried or immersed and which may be subject to stray current corrosion; the selection of
