External corrosion direct assessment process (ECDA) implemented in accordance with the NACE Recommended Practice RP0502-02 relies on above ground DA techniques to prioritize locations at risk for corrosion. Frequently, common ECDA techniques (such as CIS, DCVG) are employed in locations affected by stray currents. The paper investigates the limitations to applicability of the CIS and DCVG techniques under stray current conditions.
