NACE TM0294-2016

This NACE International test method 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 (Ti) mesh, commonly used for cathodic protection (CP) of atmospherically exposed steel-reinforced concrete.

This test method presents two methods for evaluating the anode material; Test Method Part A is intended to evaluate whether an embeddable anode material complies with minimum required specifications of design life expectancy at rated current output. Test Method Part B is a quicker test to ensure that a sample from a particular batch of material is suitable. Test Method Part B shall only be conducted on samples of a product that has passed Test Method Part A for the required design life. The test methods are not applicable to surface-mounted anodes or conductive coating materials.
