Polarization measurement and an accelerated life test of the oxide‐coated titanium anodes in relatively dilute solutions of and in solution were conducted. The OCTA failed at potentials higher than 1.3V vs. SCE, probably due to anodic oxidation of and passivation of Ti substrate. An accelerated life test based on those results has been investigated to estimate the OCTA. The polarizing current decreases quickly when the OCTA becomes inactive, and the service life of material is evaluated by the time‐to‐failure from the start‐up.
