Salt fog test is a kind of environmental test to evaluate the corrosion resistance of products or metal materials by artificial simulated salt fog environment created by salt fog test equipment. It is divided into two categories, one is the natural environment exposure test, the other is artificial accelerated simulation salt spray environmental test. Artificial simulation of salt spray test is the use of a box of salt fog test equipment has a certain volume of space, artificial methods used in the volume of space, resulting in the salt spray environment to carry out the assessment of product quality of salt spray corrosion resistance. Compared with the natural environment, the salt concentration of chloride salt fog environment, can be several times the general natural environment of salt fog content or a few times, the corrosion speed is greatly improved by salt spray test on the product, the results of the time is greatly shortened. If a sample of a product is tested in a naturally exposed environment, it may take 1 years to do so, and a similar result can be obtained in 24 hours under simulated salt fog conditions. Artificial simulation of salt spray test and neutral salt spray test, salt spray test, copper accelerated acetic acid salt spray test, cyclic salt fog test. (1) neutral salt spray test (NSS test); It is the earliest and most widely used method of accelerated corrosion test at present. It uses 5% NaCl solution, and the pH of the solution is in neutral range (6~7) as a solution for spraying. The test temperature is 35 DEG C, and the sedimentation rate of salt fog is between 1 and 2ml/80cm2.h. (2) acetic acid salt spray test (ASS test) It was developed on the basis of neutral sal
