Low-pressure (altitude) chamber tests
are performed to determine if materiel can withstand, and operate in, a
Examples of some problems that could
occur as a result of exposure to reduced pressure are:
Leakage of gasses or fluids from
Rupture or explosion of sealed
Change in physical and chemical
properties of low density materials.
Erratic operation or malfunction of
equipment resulting from arcing or corona. Electrical resistance of the
atmosphere decreases with altitude up to around 120,000 feet, and then
it begins to increase again.
Overheating of equipment due to
reduced heat transfer.
Evaporation of lubricants.
