Salt Spray Test Machine- ISO 9227 SST Chamber

Joeo factory are professional produce salt spray test machine 
Our engineer team are following marketing develop demand ,  Developed a new style salt testing machine can use space more efficiently, improve the efficiency of testing.  With old model only can use about 50% test area, but with our new design 2024 model of salt spray test machine , The space rate of the laboratory box is as high as 90%, which is a disruption in the industry. For users and laboratories who purchase salt spray testing, it provides more efficient use of space, saves costs and improves test efficiency.
 

Structure

JOEO salt spray test equipment adopts 5mm or 8mm imported gray and white impact resistant P.V.C board, with high temperature resistance up to 85℃ and corrosion resistance. 
Support frame: ¢ 10MM fiberglass rod, corrosion resistant. The steel V-frame and the fiber rod angle are placed to ensure the specimen is inclined at 15-30 degrees. 
Pressure barrel is welded seamlessly with 2.0mm SUS304 stainless steel plate 

JOEO salt spray test machine can be divided into three categories: 

(1)Neutral salt spray 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 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 about 3, the solution becomes acidic, and the salt mist formed finally becomes acidic 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.
