Gas corrosion reliability testing

Gas corrosion reliability testingIt is a testing method used to evaluate the corrosion resistance of materials or products in specific gas environments. This type of experiment usually uses corrosive gases to accelerate the corrosion of materials or products under certain temperature and relative humidity conditions, in order to simulate the corrosion situations that materials or products may encounter in actual use environments. It can help determine the corrosive effects of indoor environments during work or storage on electrical and electronic components, equipment, materials, especially contacts and connectors.

The commonly used corrosive gases in gas corrosion testing include:

sulfur dioxide(SO₂)

nitrogen dioxide(NO₂)

chlorine gas(Cl₂)

hydrogen sulfide(H₂S)

These gases accelerate the corrosion of materials under specific temperature and humidity conditions, which can simulate the corrosion situations that may be encountered in actual environments.
