High Temperature Test Chamber for Heat Aging
Apply controlled dry heat to components, materials and assemblies during high-temperature storage, powered operation, heat aging and thermal-stress testing. DERUI configurations are selected from the maximum temperature, loaded workspace, specimen heat capacity and applicable method.
What This Heat-Only Chamber Is Designed to Do
A high-temperature test chamber is optimized for sustained elevated-temperature exposure. Unlike a refrigerated temperature chamber, it normally does not provide cold testing; unlike a thermal-shock chamber, it does not transfer specimens abruptly between zones.
High-temperature storage
Evaluate parameter drift, insulation deterioration, solder/interconnect weakness and material degradation.
Powered operation and burn-in
Run energized components with suitable feedthroughs after internal heat and safety controls are included in the calculation.
Material heat aging
Condition polymers, seals, coatings, adhesives and composites before post-exposure measurement.

Define the Loaded Thermal Test
Set the exposure
Provide every setpoint, ramp, dwell, cycle, interruption rule and applicable standard revision.
Describe the load
State dimensions, quantity, mass, material, shelf layout and internal heat generation.
Define acceptance
Specify air and specimen sensors, stabilization, sampling, uniformity survey and report format.
High Temperature Chamber Reference Image
DERUI high-temperature chamber reference image. Final workspace, door, controller, ports and safety configuration follow the approved technical agreement.
Construction, Loading and Safety Priorities
Forced-air circulation
Review specimen spacing and fixture blockage so conditioned air reaches the intended test space.
Independent over-temperature protection
Specify a protective limit independent from the main control channel and appropriate alarm response.
Powered-specimen interfaces
Define cable ports, specimen watts, external supplies, cut-off logic and monitoring points.
High-temperature materials
Confirm liner, insulation, seals, shelves, cables and windows are suitable for the selected maximum temperature.
Heat rejection and access
Check room ventilation, electrical supply, transport path, service clearance and floor loading.
Specimen hazard review
Batteries, flammables and gas- or smoke-producing samples need written engineering approval and dedicated controls.
Standards and Test-Method Alignment
| Reference | Relevant scope | Selection implication |
|---|---|---|
| IEC 60068-2-2 | Dry heat for heat-dissipating and non-dissipating specimens | Confirm specimen state, airflow, measurement, stabilization and reporting. |
| ISO 16750-4 | Climatic loads for vehicle electrical/electronic components | Use the severity and test appropriate to mounting location and product specification. |
| MIL-STD-810 Method 501 | Tailored high-temperature environmental testing | Apply the required procedure and cycle; avoid blanket compliance claims. |
| JESD22-A103 / A108 | Storage life and biased operating-life testing | Confirm tolerance, duration, electrical interfaces and specimen heat. |
Recommended Test Workflow
Baseline specimens
Record appearance, dimensions, electrical characteristics or other required pre-test values.
Load consistently
Maintain repeatable spacing and keep the chamber sensor and circulation paths clear.
Monitor specimens
Add calibrated thermocouples when stabilization or powered operation must be verified.
Run and record
Capture chamber temperature, specimen temperature, alarms, interruptions and cumulative time.
Cool safely
Follow the method’s conditioning and handling requirements before post-test measurement.
Evaluate defined criteria
Compare post-test results with baselines and perform failure analysis where needed.

Frequently Asked Questions
How is this different from an industrial oven?
A test chamber is selected for controlled test-space uniformity, programmable exposure, calibrated measurement, specimen access and repeatable reliability testing.
Can every model run from ambient +10°C to +300°C?
No. This is the published overall configurable range. Confirm the selected size, construction, continuous limit and loaded performance.
Can it run for 1,000 hours or longer?
Yes when chamber duty, utilities, maintenance, alarms, data backup and interruption handling are designed for the programme.
Can specimens be powered?
Yes when feedthroughs, specimen heat, safety interlocks and monitoring are included in the selected configuration.
Can it perform cold or thermal shock testing?
No. Choose a refrigerated chamber for cold cycling or a thermal-shock chamber for rapid zone transfer.
What is needed for a quotation?
Send the profile, standard, specimen size/quantity/mass, heat load, workspace, ports, records, voltage and installation conditions.
Configure the Chamber from the Loaded Dry-Heat Test
Send the maximum temperature, specimen layout, heat load, dwell time, standard and data requirements. DERUI can confirm volume, heating, airflow and safety configuration.
