Abstract: Mathematical (numerical and analytical) and/or empirical models to predict corrosion rate (icorr) have been proposed in past studies, and were in some cases validated using either natural or accelerated icorr results. In the majority of cases, accelerated corrosion experiments have been used to obtain data relating to icorr and/or corrosion-induced damage. The use of this type of data for model validation can be criticized for various reasons including the fact that it does not adequately simulate natural corrosion processes. Consequently, its use for the validation of mathematical models can be questioned. Aiming at linking natural and accelerated corrosion, this paper presents and discusses both natural and accelerated corrosion results, and an initial attempt to correlate the two. Even though a reasonable correlation between natural and accelerated icorr is presented here, more data are still required to ascertain the relationship.
