High Temperature Test Chamber for Heat Aging and Thermal Stress Testing
A forced-air dry-heat chamber for evaluating how components, materials and assemblies perform during elevated-temperature storage, operation and accelerated aging. DERUI configurations are available in multiple working volumes and temperature classes, with the chamber selected around the specimen load and governing test method.
What This Chamber Is Designed to Do
A high temperature test chamber creates a controlled dry-heat environment around the test specimen. It is used for high-temperature storage, operating-temperature evaluation, heat aging, component screening, material conditioning and process verification.
Unlike a general industrial oven, a reliability test chamber is selected for test-space uniformity, programmable exposure, traceable temperature records, specimen access and repeatable loading. Unlike a temperature cycling chamber, a heat-only chamber normally has no refrigeration and is optimized for sustained elevated-temperature testing.
Typical Applications and Failure Modes
ชิ้นส่วนอิเล็กทรอนิกส์
High-temperature storage and powered-operation exposure can reveal parameter drift, insulation deterioration, solder or interconnect weakness and material degradation.
Automotive electronics
Validate sensors, control modules, connectors and electrical assemblies against temperature requirements appropriate to their mounting location and operating state.
Polymers and elastomers
Condition plastics, seals, cable insulation and composite materials before evaluating discoloration, cracking, hardness, mass or mechanical-property changes.
Coatings and adhesives
Screen cured coatings, bonding systems and encapsulants for loss of adhesion, softening, embrittlement, blistering or dimensional change after heat exposure.
Assemblies and enclosures
Evaluate thermal expansion, clearances, deformation, fastener performance and functional stability of complete products or subassemblies.
Production quality control
Run repeatable burn-in, heat soak or batch-conditioning profiles with documented time, setpoint and alarm records.

A chamber does not receive universal “compliance” simply because it can reach a specified temperature. Compliance depends on the complete procedure, calibrated instrumentation, loading, tolerances, specimen operation and reporting required by the applicable standard.
How to Select the Correct Configuration
Define the test profile
Provide every setpoint, ramp, dwell, cycle, interruption rule and required standard revision.
Define the specimen load
Supply dimensions, quantity, total mass, material, shelf layout and whether specimens generate heat.
Select usable volume
Allow clearance for airflow, cable routing, instrumentation and safe loading—not only the outer specimen dimensions.
Confirm measurement needs
Specify chamber sensors, specimen thermocouples, data channels, sampling interval and report format.
Review utilities
Verify voltage, phase, breaker capacity, room heat rejection, access route and floor loading.
Approve acceptance testing
Define the temperature survey, calibration evidence, loaded test and factory acceptance criteria.

- Pre-inspect and baseline the specimens. Record appearance, dimensions, electrical characteristics or other values required by the test plan.
- Load without blocking airflow. Maintain consistent spacing and keep specimens clear of the chamber sensor unless the method specifies otherwise.
- Install monitoring sensors. Use calibrated specimen thermocouples where stabilization or powered operation must be verified.
- Run the approved program. Record chamber temperature, specimen temperature when required, alarms, interruptions and cumulative exposure time.
- Cool and condition safely. Follow the test method before handling or measuring hot specimens.
- Evaluate against defined criteria. Compare post-test results with baseline and reference specimens; avoid attributing every change to temperature without failure analysis.
คำถามที่พบบ่อย
What is the difference between a high temperature chamber and an industrial oven?
Both provide heat, but a test chamber is normally selected for controlled test-space uniformity, programmable exposure, calibrated measurement, specimen access and repeatable reliability testing. The correct choice depends on the required method and tolerances.
Can one chamber cover room temperature +10°C to +300°C?
DERUI publishes configurations across this overall range, but not every chamber size and construction is guaranteed to cover the entire range with identical performance. Confirm the selected model’s continuous operating range and loaded performance.
