PROBLEM TO BE SOLVED: To provide a corrosion testing method and a corrosion testing system suitable for evaluating a corrosion resistance of an electric wire with terminal utilized in an environment in which corrosion advances relatively slowly. SOLUTION: This corrosion testing method includes the steps of preparing a pair of samples 1 having a terminal member 11 attached to the end of the electric wire 10 provided with an insulation layer 10i on an outer circumference of a conductor 10c; arranging each of the samples 1 with the terminal members 11 thereof separated from each other; preparing an electrolyte carrier 4 having an electrolyte adhered to a granular surface of a nonmetallic insulating material; bringing the electrolyte carrier into contact with both the terminal members 11 and arranging the same so as to be interposed between both the terminal members 11; charging the samples 1 into a constant-temperature, constant-humidity device 2 in this state to hold at a constant temperature and a constant humidity; and applying a constant voltage to both the samples 1 for a predetermined time by a voltage application device 3. A fluid containing electrolyte generated by the electrolyte of the electrolyte carrier 4 and moisture in an atmosphere of the constant-temperature, constant-humidity device 2 is interposed between both the terminal members 11. Utilizing this fluid, a leak current runs and corrodes the terminal members 11. COPYRIGHT: (C)2011,JPO&INPIT
