适用范围：This Technical Specification is applicable to buried cathodically protected metallic structures and influencedby a.c. traction systems and/or a.c. power lines.In this document, a buried pipeline (or structure) is intended as buried or immersed pipeline (or structure), asdefined in the Standard EN 12954.In the presence of a.c. interference, the criteria given in EN 12954, Table 1, are not sufficient to demonstratethat the steel is being protected against corrosion.This Technical Specification provides limits, measurements procedures and information to deal with long terma.c. interference and the evaluation of a.c. corrosion likelihood.Even though short term interference can cause damages to buried pipelines (e.g. arc fusion), this standarddoes not deal with short term interference.
