What is Salt Spray Test ?

The salt spray test is one of the environmental tests. And it is usually carried out under artificial simulated salt spray conditions. The test mainly assesses the corrosion resistance of products or metal materials.

The following are several types of salt spray tests:

In this article, we mainly describe the artificial acceleration simulation salt spray environment test.

The artificial simulated salt spray environmental test is conducted using a salt spray chamber. The salt spray environment is artificially manufactured in the volume space of the test equipment to assess the salt spray corrosion resistance quality of the product.

The salt spray test standard is a clear and specific regulation of the salt spray test conditions, such as temperature, humidity, sodium chloride solution concentration and pH value. In addition, the performance of the salt spray test chamber is also very important.

There are several methods for determining the salt spray test results:

The products that require salt spray testing are mainly metal products.Through tests to assesses them salt resistance.

Why Do You Need a Salt Spray Chamber?

Corrosion is the destruction or deterioration of a material or its properties caused by the environment. Most of the corrosion occurs in the atmosphere, which contains corrosive components and corrosive factors such as oxygen, humidity, temperature changes, and pollutants. Therefore, salt spray detection of products is very important.

Salt spray corrosion is a common and most destructive atmospheric corrosion. The corrosion of the surface of the metal material by the salt spray is caused by the electrochemical reaction of the chloride layer which penetrates the metal surface and the protective layer and the internal metal. Artificial simulated salt spray environment test Compared with the natural environment, the concentration of chloride in artificial simulated salt spray environment can be several times or several times of the salt content of the general natural environment. Therefore, Artificial simulated salt spray environment test greatly improves the corrosion rate. Besides, it also can shorten the time to get the results. If a product sample is tested in a natural exposure environment, it may take up to 1 year for corrosion. In the artificial simulated salt spray environment, it takes only 24 hours to get similar results.

Artificial Simulated Salt Spray Test Classification

The alternating salt spray test is a comprehensive salt spray test, which is actually a neutral salt spray test plus a constant temperature humidity test. Through the penetration of the moist environment, salt spray corrosion is generated not only on the surface of the product, but also inside the product. It is to alternate the product under the salt spray and high temperature humidity environment conditions.Finally, check whether the electrical and mechanical properties of the whole product are changed.

The BE-8209 series salt spray chamberis especially suitable for alternating salt spray tests. The outer material of the chamber is Cold and heat resistant steel plate with spray coating. The internal material is Acid and alkali resistant SUS316 material. Programmable control via touch screen for remote monitoring and data acquisition.

In addition, this environmental test chamber has other accessibility features:

Do You Need an Environmental Chamber for Your Business?

Salt spray test is an important means to assess the resistance of products or materials to salt spray corrosion. The scientific and rational test results are of great importance. To improve the effectiveness of the salt spray test results, the test technique is the key.
