Low-pressure (altitude) chamber tests are performed to determine if materiel can withstand, and operate in, a low-pressure environment, and withstand rapid pressure changes. Examples of some problems that could occur as a result of exposure to reduced pressure are:

1. Rupture or explosion of sealed containers.

2. Change in physical and chemical properties of low-density materials.

3. Erratic operation or malfunction of equipment resulting from arcing or corona.

4. Overheating of equipment due to reduced heat transfer.

5. Failure of hermetic seals.

The TDS Recon is tested to 15,000 feet at 23° C (73° F). Rapid decompression is performed at 2,000 feet per minute.
