Low Pressure (Altitude) Testing

MIL-STD-810, Method 500 • RTCA/DO-160, Section 4

Low Pressure (Altitude) Testing is typically performed on items that are exposed to reduced pressure while at an elevated ground location or in an aircraft. Testing is mainly performed in the following categories:

  • Storage/Air Transport Testing
  • Operational Testing

Dayton T. Brown, Inc. has several test facilities available that can simulate altitude conditions from sea level to 80,000 ft. Our chambers are equipped to provide environmental temperature conditions from -65°F to +300°F and also have sufficient capacity to allow the introduction of cooling air during testing.

DTB has the following chambers available to support this type of testing:

  • A 4 ft. chamber (approximately 4 ft. x 4 ft. x 4 ft.), which is capable of performing temperature and Low Pressure (Altitude) Testing
  • A 20 ft. chamber (approximately 20 ft. x 8 ft.), which can simultaneously conduct Combined Environment Testing of temperature and altitude to a maximum +350°F and 70,000 ft.
  • A 6 ft. chamber (approximately 6 ft. x 4 ft. x 4 ft.), which is capable of conducting Combined Environment Testing of temperature, altitude, humidity, and icing

We can perform Low Pressure (Altitude) Testing to the following requirements:

  • MIL-STD-810, Method 500
  • RTCA/DO-160, Section 4
