Pressure Testing according to RTCA DO-160 and MIL-STD-810

Pressure testing is necessary for every airplane. Airplane equipment hast to operate properly at different pressure levels. A sudden loss of pressure can have disastrous consequences for the aircraft's navigation, safety, and operating systems. Depressurization can result in leakage and electrical failure in addition to rupture and structural collapse.

In our laboratories, we conduct testing at a variety of pressure levels, supporting you with standards like RTCA DO-160 and MIL-STD-810, as well as individualized projects.

Altitude Testing

Altitude testing is performed in order to see how equipment behaves when stored, operated, or transported at high elevations with low pressure.

If not stored, the device is operated at its full duty cycle during the altitude testing. The pressure in the altitude test chamber is then reduced. The temperature is stabilizing while the pressure is reduced during this test, which begins at ambient temperature.

For a wide range of product types, our laboratories can simulate altitudes up to 21.336 meters equivalent to 44,4 mbar.

Overpressure Testing

Overpressure testing is used to examine the behavior of the aircraft during phases with increased pressure.

Pressure testing – altitude testing: Tests at different pressures

Decompression Testing

Decompression testing is used to test airplane avionics by simulating rapid decrease in pressure. The chamber fulfills the RTCA DO-160 test specification's environmental conditions and test procedures for flying equipment.

Decompression Testing assesses the aircraft's response to rapid decrease in pressure within 15 seconds. (or less)

For example from 8000 ft (2438m) 752,6 mbar to 55.000 ft (21.300 m) 91,2 mbar according to RTCA/DO -160.

Explosive Decompression Testing

Explosive decompression testing analyzes how aircraft equipment reacts to even faster pressure drops than the decompression testing, in not more than 0,1 second.

For example from 8000 ft (2438m) 752,6 mbar to 40.000 ft (12.192 m) 186,8 mbar according to MIL-STD-810.
