1. Introduction.

1) Corrosion of applied and unprotected metal materials is affected by many environmental factors, depending on the type of metal material and the type of environment, so chamber tests are designed to simulate the primary role of corrosion of metal materials. This equipment is designed to simulate the effects of simulated and increased environments on metal materials exposed to salt-contaminated and accelerated corrosive outdoor atmospheres. The equipment contains a test method for circulating the sample to a salt spray, dry, hot and humid environment. It is a comparative test, the test results can not be predicted in this environment under the use of the same kind of metal material corrosion resistance. It has the greatest advantage over conventional accelerated corrosion tests such as neutral salt spray test (NSS), acetic acid salt spray test (AASS), copper accelerated acetic acid salt spray test (CASS) Reproduction occurs in the outdoor salt pollution under the environment of corrosion.

2) The equipment applies to: metal and its alloys, metal cover (anode and cathode), conversion coating, anodized coating, metal materials, organic cover, etc.
