Salt Spray Corrosion Test Chamber TT-B117
Salt Spray Corrosion Test Chamber TT-B117
Salt Spray Corrosion Test Chamber TT-B117 is an environmental testing apparatus primarily utilized to replicate salt spray conditions for assessing the corrosion resistance of products or metal materials.
(1) The neutral salt spray test stands as one of the most widely utilized accelerated corrosion testing methods. It uses a 5% sodium chloride solution with a solution pH value within the neutral range (6 to 7) as the spray solution. Test conditions include a temperature of 35 degrees Celsius, with a salt spray deposition rate ranging between 1 and 2 ml/80 cm2 per hour.
(2) The acetate spray test involves the addition of acetic acid to a 5% sodium chloride solution.
(3) The copper accelerated acetic acid salt spray test is a newly developed rapid salt fog corrosion test utilized abroad. Conducted at a temperature of 50 degrees Celsius, it involves the addition of a small quantity of copper salt and copper salt solution, inducing corrosion more aggressively. This test proceeds approximately 8 times faster than the NSS test.
(4) The alternating salt spray test serves as a comprehensive salt spray testing method.
