This paper covers various methods for dealing with sources of errors affecting the accuracy of the Direct Current Voltage Gradient (DCVG) coating defect identification and sizing tool. Topics reviewed in detail include: eliminating the influence of local soil resistivity and varying pipe depth on the calculation of the %IR severity ranking index and using the DCVG in conjunction with an AC Current Attenuation (ACCA) survey.

Keywords: External Corrosion Direct Assessment (ECDA), Close Interval Potential Survey (CIPS), Direct Current Voltage Gradient (DCVG), percentage IR (%IR), AC Current Attenuation (ACCA) survey, soil resistivity, pipe depth, groundbed gradients.
