One chamber. Multiple standards..
Combined test systems integrate sequential or simultaneous environmental conditions in a single chamber — reducing certification time, transport handling, and validation scope creep.
Single-condition chambers force a sample to move between stations: temperature chamber → vibration table → IP test rig. Each handover introduces handling error and breaks the test cycle. Combined chambers run multiple conditions in one enclosure.
ULMEKA designs combined test systems to specific compliance programs. MIL-STD-810 method combinations, IEC 60529 IPX with concurrent temperature, vibration combined with humidity — engineered into a single chamber with shared instrumentation.
Why test in combination..
Real conditions are simultaneous.
Field environments stack stresses; running each factor separately rarely reproduces how a product actually fails.
Interactive failure modes surface.
Thermal expansion under vibration, condensation during temperature cycling, seal fatigue under combined heat and humidity — these appear only when stresses act together.
Standards define it.
Qualification standards such as MIL-STD-810, RTCA DO-160 and IEC 60068-2 specify combined-environment methods precisely because sequential testing under-represents real risk.
One campaign, less schedule.
A single combined system consolidates what would otherwise be several separate test runs — cutting handling, setup and program time.
Common test combinations..
Temperature + Humidity
The baseline climatic combination for most electronics and materials.
Temperature + Vibration
Thermal cycling with mechanical excitation; critical for avionics, automotive and defense electronics.
Temperature + Humidity + Vibration
“Triple combined,” the closest reproduction of real transport and operational life.
Thermal + Altitude (low pressure)
For airborne and high-altitude equipment.
Rain + Temperature
Water ingress under thermal load (MIL-STD-810 Method 506.6).
Standards that engineers ship together..
Climatic + Vibration
Temperature, humidity and vibration in a single cycle. Common for MIL-STD-810 Method 514 + 507 combined qualification.
Climatic + Shock
Thermal shock cycles paired with mechanical shock events per Method 503 + 516.
Multi-standard compliance
MIL-STD-810H Method 506.6 Rain combined with IEC 60529 IPX — single chamber satisfies both certification paths.
Modular configuration
Climatic, vibration, IP and altitude modules ship as building blocks. Combined per program requirement, not pre-baked.
Where combined systems pay off..
Defense product qualification
MIL-STD-810H method clusters run end-to-end without inter-test handling. Reduces qualification cycle time and chain-of-custody friction.
Aerospace avionics
DO-160 combined with MIL-STD-810 in shared chamber — single test plan, single report, fewer scheduling dependencies.
Automotive electronics
Climate and vibration profiles for connector and ECU qualification — concurrent loading reflects field stress more accurately than sequential testing.
