NACE TM 0108:2012

This test method is intended to provide an indication of an anode’s ability to perform satisfactorily for a specific number of years. Because such anodes can fail with little or no weight loss, lifetime expectation cannot be extrapolated from operation at normal operating current density, and testing must be conducted at high current density until an acceptable amount of charge has been accumulated. This standard is applicable for catalyzed titanium anodes intended for use in underground or underwater environments, and it is intended for use by consultants, suppliers, and end users of catalyzed titanium CP anodes.
