Environmental tests are used to verify a piece of equipment can withstand the rigors of harsh environments, for example:

1.Extremely high and low temperatures
2.Large, swift variations in temperature
3.Blown and settling sand and dust
4.Very high or low humidity
5.Wet environments
6.Vibrations (airborne and structural)

Such tests are most commonly performed on equipment used Automobile, Military, Aeronautical and space applications.
