As known, ISO 15589-1 and SP0169 protection criteria refers to IR-Free potentials values to be met by applying cathodic protection to limit corrosion rate and, at the same time, to avoid overprotection: in this respect, according to the type of currents influencing the metallic structure, European standard EN 13509 proposes different measurement techniques for measuring IR Free potential.

As known, main international standards (ISO 15589-1 and SP0169) protection criteria refer to IR-Free potentials values to be met by applying CP to limit corrosion rate and at the same time to avoid overprotection: in this respect, according to the type of currents influencing the metallic structure, EN 13509 standard proposes different measurement techniques for measuring IR Free potential.
Off potential measurements are usually performed, both on pipeline and by means of coupon, to try catching the best approximation for the IR-free potential value: for this reason, a fully understanding of all the components that contribute to the obtained potential measure is of very great importance for making better assessment.

Experiments and corrosion modeling were conducted - with 10, 50, and 100 cm2 coupons in circular, triangular, and cylindrical shapes - to develop an approach to evaluate optimal cathodic protection (CP) coupon size and shape for monitoring CP in field.
