Cathodic Disbondment (CD) testing has historically been performed on protective coatings in order to assess the resistance of damage to a coating when exposed to cathodic polarization. Unfortunately there is no broadly accepted high temperature CD testing standard in the pipeline industry. Broadly disparate durations electrolyte types potentials electrolyte temperatures and sample testing temperature characterize the varying methods and practices currently used. This paper reviews various critical factors that will affect the high temperature CD behavior of a FBE based pipeline coating highlighting a need of developing a definitive high temperature CD testing procedure that is stable understood easy to run (with the correct equipment and experience) and provides reproducible results. Results of a real offshore pipeline project are presented and a testing protocol is proposed.

The research described in this paper was carried out with the objective of establishing any correlation between coating performance and the results of cathodic disbondment testing. Experiments were carried out using 13 coatings. Nine samples of each coating were studied in a total of 117 experiments.

The cathodic disbondment (CD) test is a well known and generally accepted laboratory test for pipeline coatings for a long time. What are we testing and what is the significance of the test? By means of basic investigations factors influencing cathodic delamination have been identified and their extent on the delamination radius has been assessed.
