摘要： PURPOSE:To accurately carry out the fatigue test of a test piece in corrosive environment by supplying the corrosive medium adjusted to predetermined temp. in a thermostatic tank to a corrosion tank. CONSTITUTION:The corrosive medium 12 adjusted to predetermined temp. within a thermostatic tank 1 naturally flows down from a supply port 6 to reach the water supply port 31 of a corrosion tank 3 to be guided to the corrosion tank 3. The medium 12 guided to the corrosion tank 3 is used in the corrosion of the test regions 4a of a test piece 4 and subsequently overflows from an overflow port 32 and naturally flows down to be quided into a storage tank 2 from the water supply port 9 of the storage tank 2. The corrosive medium 12 once stored in the storage tank 2 is taken out of a drain port 10 to be circulated to the thermostatic tank 1 from the water supply port 8 thereof by a circulating pump 5 to be adjusted to predetermined temp. The medium 12 flowing out of the overflow port 7 of the thermostatic tank 1 is also stored in the storage tank 2 and recirculated to the thermostatic tank 1 by the pump 5 and, therefore, the medium 12 does not flow out of the tank during the test.
