Low pressure (altitude)
In altitude testing of products, they are subjected to various pressure conditions in a laboratory environment to simulate changes in altitude. This testing is commonly conducted to assess the performance and safety of products when transported by air or when experiencing altitude variations during shipping and handling. Specialized environmental testing equipment, such as altitude chamber, is used for this purpose.
Low pressure (altitude) tests are to determine if materiel can withstand and/or operate in a low pressure environment and/or withstand rapid changes of pressure.
This method is used to evaluate materials likely to be:
- Stored or operated at high-altitude locations.
- Transported or used in pressurized or unpressurized aircraft compartments.
- Exposed to rapid or explosive decompression, and if so, assessed for potential failure that could damage the aircraft or pose a hazard to personnel.
- Carried externally on an aircraft.
