CNS8886 salt water spray test method standards specified metal materials and The metal -resistant test (NEUTRAL SALT Spray Test, NSS), the acetic acid spray test (ACETIC Acid Salt Test (AASS) contains copper acceleration of copper acetic acid. The chore-accelerated accelerated accetic acid Salt spray (CASS) and other test methods in test methods, test medicines, procedures and judgments methods. 
Evaluation criteria for salt fog test results:
1. AfterThe appearance of the salt fog test box The appearance after the salt fog corrosion test;
2. The appearance after removing the surface corrosion product;
3. The quantity and distribution of corrosion defects (such as erosion, foaming, rust, or organic coverage of the scratches at the scratch scratch) can be The evaluation method of the organic coverage layer described in IOS 30789.1 ~ 5 and IOS 30789.8 is evaluated;
4. The time of corrosion;
5. Quality changes;
6. Micro appearance changes;
7. Mechanical performance changes.
Note: The appropriate criteria for the test coating or product are determined in good engineering practice.

GB-T2423.17-1993 salt fog test
IOS 12967.3-91 CASS accelerate
Acetate Mist Test
Astm.b117-97 salt fog test
IOS 10125-2012 artificial atmosphere corrosion test salt fog test
According to cns.jis.astm specifications, Can set the constant temperature control:
(a) saline spray test: NSS, ACSS (1) Laboratory: 35 ℃ ± 1 ℃
(2) Pressure air barrel: 47 ℃ ± 1 ℃Air supply system: air pressure is 1kg/cm2
Spray quantity adjustment 1-2mi (Mi/80cm2/h) (16-hour average).
Spray method: Continuous and intermittently set
salt fog test machine
Main features:
1. The temperature control instrument uses a microcomputer PID control instrument, high control accuracy and good stability, which effectively guarantees the fluctuation of temperature and humidity fluctuations Scope and test operation;
2. Temperature control adopts P.I.D + S.S.R, the system is coordinated by the same channel, which can improve the stability and life of the control component and interface use, touch button formula setting Display a variety of screens of fixed and values directly display; 3. Use water purification filters automatically to ensure that the pipeline is not blocked and the service life is longer. (In this industry's first creation) 4. The laboratory water level is too high -automatic overflowing device without manual emissions, but the warming time will not be too long. 5. The heating system uses a titanium alloy heater, and the corrosion resistance will never rust, and there is a repair port. 6. The pressure barrel is made of SUS304 stainless steel. The pressure barrel is also known as the saturated air barrel is part of the core of the salt fog test box. And oil pollution filtration, so it is also known as saturated barrel
