The salt spray corrosion test chamber is mainly used to test the surface corrosion resistance of various materials after surface treatment such as electroplating, coating, painting, rust prevention, etc. The use of sodium chloride solution to act on the coated film in a mist is an important testing method commonly used in materials research, national defense industry, light industry, instrumentation and other industries. Our company's salt spray corrosion test chamber can be subjected to the central salt spray test (NSS) in accordance with GB/T2423.17 "ka: Salt Spray Test Method", and can also be subjected to the acetic acid salt spray test (ASS, CASS) according to relevant standards.
