salt spray cabinet/SO2 Sulfur Dioxide Salt spray tester JOEO

JOEO Laboratory simulated salt spray can be divided into three categories: 

(1)Neutral salt chamber test, 
(2) Acetate salt spray test, 
(3)Copper salt accelerated acetate salt spray test

(1) The neutral salt spray test (NSS test) is the earliest and most widely used accelerated corrosion test method. It uses 5% sodium chloride salt water solution, and the PH value of the solution is adjusted to a neutral range (6.5 ~ 7.2) as a spray solution. The test temperature is 35℃, and the sedimentation rate of salt spray is required to be 1～2mL/80cm/h.

(2) Acetic acsalt spray test (ASS test) is developed on the basis of neutral salt spray test. It is to add some glacial acetic  to the 5% sodium chloride solution, the pH value of the solution is reduced to about 3, the solution becomes and the salt mist formed finally becomes from neutral salt mist. Its corrosion rate is about 3 times faster than the NSS test.

(3) The copper salt accelerated acetate spray test (CASS test) is a rapid salt spray corrosion test recently developed. The test temperature is 50℃. A small amount of copper salt-copper chloride is added to the salt solution to strongly induce corrosion. Its corrosion rate is about 8 times that of the NSS test.
