How a Stationary-Specimen Three-Zone Chamber Works
The specimen remains in the 150 L test workspace throughout the cycle. Separate high- and low-temperature conditioning zones prepare hot and cold air in advance. When the programmed test changes from one condition to another, controlled dampers redirect the required air into the test workspace.
This arrangement avoids mechanically transferring the specimen between hot and cold compartments. It can be useful for samples that are heavy, delicate, instrumented or connected to monitoring cables. The chamber must still be selected according to specimen mass, fixture design, heat load and the required recovery performance.
Precondition
The hot and cold zones prepare the required air conditions.
نمایاں کریں
The stationary specimen dwells at the programmed condition.
Switch
Dampers change the airflow path within the specified conversion time.

Standards and Test-Plan Compatibility
IEC 60068-2-14:2023 addresses specified changes of ambient temperature and includes requirements for change-of-temperature tests and reporting. A chamber configuration should be selected against the exact procedure, specimen condition, severity, dwell time and tolerance required by the applicable specification.
Other automotive, aerospace, military or customer requirements may also call for temperature-shock testing. Equipment capability alone does not prove compliance with every standard. Confirm the invoked edition and procedure, then verify chamber performance with the intended load and measurement method.
Information Required to Select the Correct Configuration
Specimen and profile
- Specimen dimensions, mass and quantity
- Fixture dimensions and material
- Hot and cold setpoints
- Dwell time and number of cycles
- Required conversion and recovery definitions
Interfaces and facility
- Powered heat load and monitoring cables
- Required access ports and sensors
- Applicable standard and acceptance limits
- Power supply and installation environment
- Cooling, exhaust and service-access requirements

اکثر پوچھے جانے والے سوالات
Does the specimen move inside this DR-H203 chamber?
No. For the configuration presented in this video, the specimen remains stationary in the 150 L test workspace while dampers switch conditioned hot and cold airflow.
What are the provided temperature ranges?
The high-temperature zone is stated as room temperature to +200°C, and the low-temperature zone as −65°C to 0°C. The actual test setpoints must remain within the configured operating limits.
What is the difference between the 30-second conversion time and 3-minute recovery time?
The 30-second figure refers to changing the temperature-conditioning path. The 3-minute figure refers to the workspace recovering to the required condition. Confirm the test load, setpoints, tolerance and sensor location used for these ratings.
Which samples benefit from a stationary test workspace?
Heavy, fragile or instrumented specimens can benefit because the sample and its monitoring connections do not move between compartments. Suitability still depends on the required test standard and profile.
What should be provided for a quotation?
Send specimen dimensions and mass, hot and cold setpoints, dwell time, cycle count, required recovery performance, powered heat load, monitoring connections, applicable standard and facility power supply.
