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.
Altitude Test Chambers – Precision & Performance
Since 1953, ACS has designed vacuum test chambers for altitudes up to 150 000 feet (1 mbar). Available in 150L, 500L and 1000L, these parallelepiped chambers offer:
- Thermoregulation (optional) for optimal performance below 300 mbar
- Thermostatic & climatic models (temperature, pressure, and humidity control)
- New ES models for Environmental Stress Screening (ESS) with 5°C/min temperature change rates
- MyKratos™ control system for remote monitoring via Wi-Fi, Ethernet, or mobile network
- Optional MyAngel24™ remote assistance system
We can also provide special chambers for high vacuum tests, combined vibration tests,
icing tests, vacuum shock tests, according to customers’ specifications or standards
like MIL-STD 810 G and RTCA-DO-160.
