Service Background
The atmospheric environment encompasses temperature, humidity, oxygen, gas pollutants, and other corrosive elements and factors. Under specific conditions, these gases can react with water molecules adsorbed on metal surfaces, forming compounds that notably corrode electronic components, entire machines, and materials, particularly contacts and connectors, thereby severely affecting their electrical performance and reliability. The rigor of gas corrosion testing is determined by the type of corrosive gas and its exposure duration. By simulating various corrosive gases found in the atmosphere and subjecting materials or products to accelerated corrosion in a controlled environment of specific temperature and relative humidity, it is possible to replicate the extent of damage they would experience over a certain period, thus evaluating their resistance to atmospheric corrosion.
