Altitude Testing Capabilities at Keystone Compliance

Keystone Compliance operates an altitude test chamber capable of simulated altitudes up to 100,000 feet while providing temperature conditioning from -70 to +100 degrees Celsius.

Custom setups for altitude, rapid, and explosive decompression testing are standard procedures for the staff at Keystone Compliance.

Altitude Testing Overview

Altitude testing, also referred to as low pressure testing, per MIL-STD 810 Method 502.4, is performed to ensure that equipment can withstand and operate in a low pressure test or high altitude test environment. Altitude testing is intended to be used for air shipment of material in a plane, equipment designed for installation at high ground elevations and explosive decompression due to aircraft damage. Manufacturers of any device that is transported by air should consider the impact high altitude testing or low-pressure testing could have on their products. A low pressure test can simulate the problems high altitude can create such as:

  • Leakage of gases or fluids from gasket-sealed enclosures
  • Rupture or explosion of sealed containers
  • Change in physical and chemical properties of low-density materials
  • Erratic operation or malfunction of equipment resulting from arcing or corona
  • Overheating of equipment due to reduced heat transfer
  • Evaporation of lubricants
  • Erratic starting and combustion of engines
  • Failure of hermetic seals

Keystone Compliance assists manufacturers with altitude testing to determine a products’ ability to withstand the harsh low pressure environment of high altitude.
