ABOUT

PURPOSE:

Low-pressure (altitude) chamber tests are performed to determine if materiel can withstand, and operate in, a low-pressure environment.

ENVIRONMENTAL EFFECTS:

Examples of some problems that could occur as a result of exposure to reduced pressure are:

1. Leakage of gasses or fluids from gasket-sealed enclosures.

2. Rupture or explosion of sealed containers.

3. Change in physical and chemical properties of low density materials.

4. 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.

5. Overheating of equipment due to reduced heat transfer.

6. Evaporation of lubricants.
