The coating control by means of pore testing makes use of electrical voltage in order to uncover microscopically small defects (> 20 μm) in the coating of a surface. If even a small defect can be detected during pore testing of surface coatings, urgent action is required. Minimal flaws in the coating are sufficient to cause great damage.
