ABSTRACT The invention concerns a specimen testing procedure for studying the corrosion properties of the specimen. As taught by the invention, in the procedure are employed at least two specimens at different potentials, one of them being used as auxiliary specimen (1) which is controlled to carry its potential of repose, and the potentials of the other specimens, or principal specimens (2), being controlled relative to the auxiliary specimen in such a manner that the true corrosion current flows between the principal specimen and the auxiliary specimen. The invention furthermore includes an equivalent potentiostat comprising an auxiliary specimen (1) immersed in the electrolyte and connected to a current source (6); and at least one principal specimen (2), connected to another current source (3) to control the principal specimen to be at the desired potential relative to the auxiliary specimen.
