Environmental testing

Environmental testing is the measurement of the performance of equipment under specified environmental conditions, such as:

extremely high and low temperatures
large, swift variations in temperature
blown and settling sand and dust
salt spray and salt fog
very high or low humidity
wet environments, waterproofness, icing
presence of corrosive material
fungus, fluids susceptibility
vibrations (airborne and structural), gun fire
accelerations
solar radiation
high and low pressures (especially for aeronautical and space equipment)
operating at angles (especially for marine, aeronautical and space equipment)
electromagnetic interference (EMI), ESD, Lightning
acoustic measurements
power input variations

Such tests are most commonly performed on equipment used in military, maritime, aeronautical and space applications. See Environmental test chambers for more information about environmental testing equipment.
