The principle of:

Salt spray test chamber can do four tests: neutral salt spray test (NSS), copper accelerated acetate spray test (CASS), alternating salt spray test, acetate spray test (ASS test). Of course, not only do different tests require different solutions, but the design and structure of the chamber may also be different.If you need more models about our test equipment, please reference our chamber-testing（.）com 

 neutral salt spray test (NSS) test chamber temperature requirements in (35±2)℃, humidity greater than 95%, fog volume of 1 ~ 2mL/80cm*h nozzle pressure is 78.5-137.3kpa (0.8 ~ 1.4kGF /cm2). In the salt spray test box, the salt water containing (5 g 0.5)% sodium chloride and pH value of 6.5 ~ 7.2 is sprayed through the spray device, and the salt spray is settled on the test parts to be tested, and the corrosion state of the surface is observed after a certain time.

Second, copper accelerated acetate spray test (CASS) is to add copper chloride 2 water to 5% sodium chloride brine on the basis of general salt spray test to make its concentration 0.26g/L, and then adjust the PH with acetic acid to make the PH value of salt spray collection solution 3.1-3.3. (test reference GB/T 10125 artificial atmosphere corrosion test)

Three, the alternating salt spray test is a comprehensive salt spray test (using the alternating salt spray test box to achieve.

Four, acetate spray test (ASS test) is developed on the basis of the neutral salt spray test. It's a solution of 5% sodium chloride with some glacial acetic acid

Technical Parameters:

The salt spray test chamber is a climate simulation device that tests the corrosion of electronic equipment, metallic material, as well as some surface treatment--coating, galvanizing, organic/inorganic coating, anodizing treatment, rust-proof oil coating, etc. Performance indicators in line with requirements of GB / T5170.8 Electrical and Electronic Products, Environmental Testing Equipment, the Basic Parameters of the Test Method. The salt spray corrosion test chamber according to GB / T2423.17 Electronic and Electrical Products Basic Environmental Test Procedures Test Ka: Salt Spray Test Method for neutral salt spray test can also be used for acetic acid salt test.
