Pressure testing is necessary for every aeroplane. Aircraft 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 but also 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 is performed in order to observe how devices behave when stored, operated, or transported at high altitudes with low pressure.
The device is operated at full load during the altitude testing. Subsequently, the pressure will be reduced. At reduced pressure, the speciment is left for the temperature to stabilize..
For a wide range of product types, our laboratories can simulate altitudes up to 21,336 meters equivalent to 44.4 mbar.
Overpressure testing is used to examine the behavior of the aircraft during phases with increased pressure.
Decompression testing is used to test aircraft avionics by simulating rapid decrease in pressure. Our chamber complies with the RTCA DO-160 requirements concerning environmental conditions and test procedures for flight equipment.
Decompression testing assesses the aircraft's response to rapid decrease in pressure within 15 seconds (or less),
for example from 8,000 ft (2,438m) with 752.6 mbar to 55,000 ft (21,300 m) with 91.2 mbar according to RTCA DO-160.
Explosive decompression testing examines how aircraft equipments react to an even faster pressure drop as in decompression testing, in no more than 0.1 seconds,
for example from 8,000 ft (2,438m) 752.6 mbar to 40,000 ft (12,192 m) 186.8 mbar according to MIL-STD-810.
