Altitude, overpressure and rapid decompression tests
Validate your equipment in variable-pressure environments
Why carry out altitude and rapid decompression tests?
- Validate compliance with international standards such as MIL-STD-810, RTCA DO-160, ISO 50125-3 and IEC 60068
- Test the mechanical and electrical resistance of equipment to variations in pressure and altitude.
- Detect design faults such as leaks, structural weaknesses and electrical insulation faults.
- Ensure the safety and reliability of products intended for aeronautical, military and rail environments.
- Validate the behaviour of products transported by air to prevent deterioration due to pressure changes.
Types of altitude and rapid decompression tests
Our laboratories carry out a range of tests to simulate conditions of high altitude and variable pressure:
Altitude tests
- Altitude simulation up to 125,000 feet (about 4mbar)
- Extreme thermal conditions combining temperature and pressure in different volumes
Rapid decompression tests
- Decompression in less than 15 seconds to test the mechanical and electrical behaviour of equipment, and in less than 2 seconds for the BOEING standard
- Validation of the performance of electronic and mechanical components.
- Ultra-fast decompression in around 200ms
Overpressure and vacuum tests
- Tests up to 2 bar absolute.
- Simulation of the effects of air transport on packaging and sensitive components.
