Mixed Flowing Gas

Mixed Flowing Gas

Mixed Flowing Gas (MFG) is a type of laboratory environmental testing for products, particularly electronics, to evaluate resistance to corrosion due to gases in the atmosphere. Mixed Flowing Gas (MFG) test is a laboratory test in which the temperature, relative humidity, concentration of gaseous pollutants, and other critical variables are carefully defined, monitored and controlled.

The purpose of this test is to simulate corrosion phenomenon due to atmospheric exposure. The electronic product is exposed to gases such as chlorine, hydrogen sulfide, nitrogen dioxide, and sulfur dioxide at levels in the parts per billion range, in a controlled environmental chamber.
