(2) Acetic acid salt spray test (ASS test) is developed on the basis of neutral salt spray test. It is to add some glacial acetic acid to the 5% sodium chloride solution, the pH value of the solution is reduced to abou 3, the solution becomes acidic, and the salt mist formed finally becomes acidic from neutral salt mist. Its corrosion rate is abou 3 times faster than the NSS test.
(3) The copper salt accelerated acetate spray test (CASS test) is a rapid salt spray corrosion test rece
