标准范围

This International Standard is applicable to buried cathodically-protected pipeline that is influenced byAC traction systems and/or AC power lines.In the presence of AC interference, the protection criteria given in ISO 15589-1 are not sufficient todemonstrate that the steel is being protected against corrosion.This International Standard provides limits, measurement procedures, mitigation measures, andinformation to deal with long term AC interference for AC voltages at frequencies between 16,7 and60 Hz and the evaluation of AC corrosion likelihood.This International Standard deals with the possibility of AC corrosion of metallic pipelines due toAC interferences caused by inductive, conductive or capacitive coupling with AC power systems and themaximum tolerable limits of these interference effects. It takes into account the fact that this is a longtermeffect, which occurs during normal operating conditions of the AC power system.This International Standard does not cover the safety issues associated with AC voltages on pipelines.These are covered in national standards and regulations (see e.g. EN 50443).
