Abstract: | The “on site” EIS evaluation of coatings on steel constructions immersed in water or splashed by water is much more difficult than in atmospheric conditions. There are many technical problems with insulation of electrical connections, the mounting and leak tightness of measurement cell and the exclusion of measurement of electric capacitance between the counter electrode and surrounding constructions. These problems were successfully solved by the team of scientists from Road and Bridge Institute, Atlas Sollich Electronic Systems Ltd. and Trento University. The construction of the measurement cell, the investigation method as well as some of the results from “on site” coating investigation were presented. |
