Most of the products used in the atmosphere are in the atmosphere, and most of the corrosion occurred in the atmospheric environment, the atmosphere contains oxygen, humidity, temperature changes and pollutants and other corrosive factors and corrosion factors. The atmospheric environment leads to the formation of water film on the surface of metal. In the atmosphere, there are H2S, SO2, NO2, Cl2 and other harmful gases dissolved in the water film formed on the metal surface, as corrosive ions to accelerate the corrosion process.
In a certain temperature and humidity environment, the use of H2S, SO2, NO2, Cl2 and other harmful gases on the material or product to accelerate corrosion, to reproduce the material or product within a certain period of time suffered damage. The ability of the test material and the protective layer to resist gas corrosion, as well as the similar quality of the protective layer, can also be used to assess the ability of certain products to resist gas corrosion.
Gas corrosion test Scope: Communications products and peripheral parts, automotive electronics, electronic components, connectors, metal materials, electrical and electronic products such as protective layer and electronic electrical products.
Guideline: EIA-364-65-1998; GB / T 2423.51-2000; IEC 60068-2-60-1995;
The results determine: Contact resistance and other electrical performance inspection, mechanical properties and visual inspection.
