General

This standard provides a test method to evaluate coatings containing conductive carbon additive for use as an anode on atmospherically exposed reinforced concrete. The test method primarily consists of exposing concrete test panels coated with the conductive coating to an electrochemical (EC) test under defined laboratory conditions that are intended to simulate the conditions present when cathodic protection (CP) current discharges from the anode in a working CP system. The evaluation of the coating is based on determination of coating properties (i.e., appearance, adhesion, resistivity, visual inspection, and water vapor transmission) before and after the EC test.

Accelerated tests are not possible because of the nature of coatings containing conductive carbon additive used as anodes. Therefore, this test does not reflect the accelerated whole-life performance of a conductive coating anode.

Full round-robin testing on a wide range of coatings containing conductive carbon additive has not been performed, but a number of products were tested in the original test program on which this test method is based and by a laboratory in Europe.1

The results of this test method cannot be used to guarantee the performance of a product in any given field exposure condition. The product also should be field tested, or existing field performance data should be collected whenever possible to demonstrate its suitability for the particular application intended
