Performance and Functional Continuity Under Low-Pressure Conditions

Low Pressure (Altitude) Test

The Altitude Test is performed to evaluate the performance and durability of products and systems when exposed to low air pressure at high-altitude conditions. This test is critical, particularly for the aerospace, defense and electronics industries.

Objective Target

  • To verify the effects of low air pressure, temperature variations and oxygen levels on the product.
  • To test sealing performance, structural integrity, cooling systems and functional operability.

Test Scope Scope

  • High-altitude (low-pressure) simulations
  • Rapid pressure changes (rapid climb/descent scenarios)
  • Altitude + temperature combinations (low-temperature conditions at high altitude)

Technical Implementation Process

  • During the Low Pressure / High Altitude Test, there must be absolutely no air exchange between the High Altitude Test Chamber and the external environment.
  • For this reason, all interfaces of the test specimen (communication lines, power cables, etc.) are routed to the laboratory environment through hermetic feedthroughs via the chamber side ports.
  • This enables functional testing to be performed safely and reliably throughout the test.

Application Areas Use

  • Aircraft and helicopter components
  • Electronic equipment
  • Fuel systems and pressurized vessel systems
  • Defense systems and munitions

STEST conducts low pressure / high altitude tests in accordance with MIL-STD-810 using advanced test chambers. Throughout the test program, your products are evaluated against international standards and comprehensive test reports are provided.
