The corrosion test cabinet allows corrosion tests to be carried out according to DIN EN ISO 6270-2 or DIN EN ISO 6988 or comparable national and international standards. The test chamber volume is 300 l for a test chamber size of B / T / H1 / H2: 800 x 600 x 520 x 733 mm. An additional exhaust air valve, which is closed during the condensation water phase, is installed for carrying out the Kesternich-tests with SO2. After switching to the ventilation phase, this valve is opened. After a cycle has elapsed, the floor pan is emptied after opening the floor drain valve. At the start of another cycle, the floor drain valve is closed and the floor pan is filled with fresh demineralised water.
