This NACE International standard has been prepared to provide users and manufacturers of embeddable anodes with a test method for evaluating the anode material to an expected lifetime criterion. It is applicable to embeddable anode materials, such as titanium mesh, commonly used for cathodic protection of atmospherically exposed steel-reinforced concrete. The test is intended to evaluate whether an embeddable anode material complies with minimum required specifications of design life expectancy at rated current output. This test method is not applicable to surface-mounted anodes or conductive coating materials.
This NACE International test method was prepared by Task Group T-3K-6 on Test Procedure for Anodes Used in Concrete, a component of Unit Committee T-3K on Corrosion and Other Deterioration Phenomena Associated with Concrete, and is issued by Group Committee T-3 on Corrosion Science and Technology.
Accelerated testing of anodes for use in concrete is intended to provide an indication of an anode's ability to perform satisfactorily for a specific number of years. Unfortunately, accelerated "life testing" cannot be conducted in concrete because testing at high current levels results in premature failure of the concrete as the test electrolyte. Accelerated life testing must therefore be conducted in an aqueous solution.
