Altitude Chambers

Temperature testing at altitudes up to 100,000 feet.

ESPEC can provide custom-built chambers for simultaneous testing of temperature and low-pressure altitude conditions. Two common applications are:

  • Testing of avionics or other aerospace equipment to simulate actual conditions it might experience.
  • Simulation of high-altitude conditions like might be found in mountainous regions.

Applicable test methods (depending on chamber system specified)

  • Mil-Std 202G (conditions 105C, A/B/C/F)
  • Mil-Std 810G (condition 500.5)
  • IEC 60068-2-39
  • IEC 60068-2-40
  • RTCA/DO-160F
  • JIS W 0812

NOTE: Altitude chambers are custom systems, and differing requirements may significantly change the cost and utility requirements. Please let ESPEC know as much detail as possible about your anticipated testing specification/method, and we can provide you with a tailored system for your requirements.
