Salt spray test

Salt spray test is an environmental test that uses artificially simulated salt spray environmental conditions created by salt spray test equipment to confirm the corrosion resistance of products or metal materials.The simulated salt spray in the Star Magnetic Laboratory can be divided into two categories: neutral salt spray test and alternating salt spray test.

(1) The neutral salt spray test is to spray salt water containing (5±0.5)% sodium chloride and a pH value of 6.5 to 7.2 through a spray device in a specific test box to allow the salt spray to settle until theOn the test piece, observe its surface corrosion state after a certain period of time.

(2) The alternating salt spray test is a comprehensive salt spray test, which alternately converts the product under two environmental conditions, salt spray and damp heat, and finally checks whether the electrical and mechanical properties of the whole product have changed.
