Walk In Programmable Salt Spray Tester E002W-8m3

The salt spray test is designed to test the corrosion resistance of products made of various materials after their surfaces have been treated with anti-corrosion treatments such as electroplating, anodic treatment, spraying, and rust prevention oil.

Salt Spray Test Concept

The salt spray test is an environmental test that uses salt spray test equipment to create artificially simulated salt spray environmental conditions to confirm the corrosion resistance of a product or metal material. The severity of the test depends on the duration of exposure.

Laboratory simulated salt spray can be divided into three categories: neutral salt spray test, acetate spray test, copper salt accelerated acetate spray test.    

 (1) Neutral salt spray test (NSS test) is the earliest emergence of the most widely used in the field of accelerated corrosion test method. It uses 5% of sodium chloride brine solution, solution pH adjusted in the neutral range (6.5 ~ 7.2) as a spray with the solution. Test temperature are taken 35 ℃, the required settlement rate of salt spray in 1 ~ 2ml / 80cm / h.

 (2) Acetate fog test (ASS test) is developed on the basis of the neutral salt spray test. It is in 5% sodium chloride solution with some glacial acetic acid, so that the solution PH value down to about 3, the solution becomes acidic, the final formation of salt spray also from neutral salt spray into acidic. Its corrosion rate is about 3 times faster than the NSS test.

 (3) Copper salt accelerated acetate fog test (CASS test) is a newly developed foreign rapid salt spray corrosion test, the test temperature of 50 ℃, the salt solution with a small amount of copper salt - copper chloride, strongly induced corrosion. Its corrosion rate is about 8 times that of the NSS test.

(4) Alternating salt spray test

Alternating salt spray test is a comprehensive salt spray test, which is actually a neutral salt spray test plus constant humidity and heat test. It is mainly used for cavity-type whole products, through the penetration of the tidal environment, so that salt spray corrosion is not only produced on the surface of the product, but also inside the product. It is the product in the salt spray and humidity and heat two environmental conditions alternately converted, the final assessment of the electrical and mechanical properties of the whole product has no change.
