RESONANCE AUTOMATION AND MACHINES@ Umardin Saifi +919990770129 SALT SPRAY TEST CHAMBER (FOG METHOD) The equipment has been designed suitably for evaluating the corrosion resistance of the surface treatment of metallic material by salt spray test method in accordance with ASTM B117, JIS Z 2371 and shall satisfy the test condition as follows. 1. The material of the test chamber shall not be corroded itself. 2. The atomizing nozzles shall not atomize directly on the test piece. 3. The drop and solution accumulated on the ceiling shall not drip on the test piece. 4. The solution dripped from the test piece shall not be used for test again. 5. The spray pressure shall be kept at between 0.7 and 1.1 Kg/cm2. 6. The exposure zone of the salt spray chamber shall be maintained at 35 ± 10C. CONSTRUCTION It consists of a test chamber, an air saturator, a solution supply tank, a control panel. Specially designed glass atomizers employing compressed air from supply line through filter regulator produce the salt spray. Control valves can adjust the air pressure for spraying and agitation of salt solution. The air from the compressor is connected to the chamber through air filter, pressure regulator and a saturation tank through which the air is bubbled & heated up electrically to maintain the temperature inside the chamber constant at 350±10C by means of a digital temperature controller. The saturation tank supplies a heated, humidified clean air for atomization of the solution. It consists of a stainless steel tank, a heater, a bubbling nozzle, an air cleaner, a pressure regulator and a pressure gauge.
