Accredited Altitude, Low Pressure and Rapid Decompression Testing
At EMC Technologies, our extensive services include accredited pressure testing programs that simulate high altitude, low pressure and rapid decompression environments.
Our Melbourne facility operates advanced chambers designed for aerospace, defence and industrial qualification where altitude conditions or sudden pressure shifts can pose operational risks.
Simulating High Altitude Environments
Low-Pressure (Altitude) Testing
We perform altitude testing at our laboratory to determine how materials, components and electronic systems behave under reduced atmospheric pressure. We use a controlled altitude test chamber to reproduce conditions equivalent to high-elevation sites, unpressurised aircraft compartments and operational scenarios where equipment must function reliably in thin air.
Typically, altitude testing assesses the following:
- Structural or material distortion
- Seal integrity and leakage risk
- Electrical performance under low pressure
- Mechanical function during altitude variation
At EMC Technologies, we also conduct altitude simulation test procedures for products intended for aviation, defence and high-altitude commercial applications.
Rapid Decompression Testing
A rapid decompression test evaluates how equipment responds when pressure drops suddenly. This scenario can occur due to aircraft cabin loss, door seal failure, or structural rupture.
Our chamber can apply controlled rapid decompression cycles to identify hazards such as enclosure rupture, component ejection or contamination events.
This testing method supports safety assessments, certification programs, and the verification of aircraft equipment designed for pressurised environments.
Meeting Rigorous Aerospace and Defence Standards
MIL-STD-810 Altitude (Method 500)
At EMC Technologies, we perform pressure testing programs in alignment with MIL-STD-810 Method 500. These procedures assess equipment exposed to altitude, explosive decompression and extended low-pressure conditions.
Our process ensures reliable and repeatable environmental simulation for airborne and high-altitude equipment.
RTCA DO-160, Section 4: Pressure Altitude
We conduct RTCA DO-160 Section 4 tests to evaluate aviation equipment performance in operational altitude environments, including both standard atmospheric conditions and extreme cabin depressurisation.
This testing verifies that the device remains safe and functional in accordance with global aerospace compliance requirements.

Our Altitude Chamber Specification
At EMC Technologies, our Melbourne facility operates an advanced chamber that supports both pressure testing and altitude simulation programs.
Key capabilities include:
- Static low pressure down to 5kPa absolute (this is equivalent to approx. 21,000 metres)
- Altitude test chamber configuration suitable for large and small samples
- Controlled altitude simulation test profiles

FAQs about Altitude, Pressure and Rapid Decompression Testing
What is the difference between low pressure (altitude) testing and rapid decompression testing?
Low pressure testing assesses performance under gradually reduced atmospheric pressure. Rapid decompression testing evaluates the effects of sudden pressure loss.
Which specific risks does rapid decompression testing help with?
Rapid decompression identifies enclosure rupture, seal failure, component ejection hazards and any behaviour that could endanger aircraft systems or personnel.
What is the highest altitude your chamber can simulate?
At EMC Technologies, our chamber can reach pressures equivalent to approximately 21,000 metres, suitable for extreme altitude testing and aircraft-related qualification.
Why do products often fail during altitude testing?
Failures can occur due to material expansion, seal leakage, reduced cooling efficiency or mechanical malfunction under low-pressure conditions.
How long does a typical altitude or rapid decompression test take?
Typically, altitude or rapid decompression testing depends on the applicable standard and sample type. Some rapid decompression cycles take under 15 seconds, while extended altitude exposures may run for several hours.
