Test Equipment & Setup
| Parameter | Detail |
|---|---|
| Instrument Name | Thermal Shock Test Chamber (冷热冲击试验机) |
| High-Temperature Condition | 60 °C, Humidity 80 % RH, Duration 2 hours |
| Low-Temperature Condition | −20 °C, Duration 2 hours |
| Total Storage Duration | 72 hours |
| Post-Test Check | Functional test (功能测试) |

Test Procedure
- Pre-Test: Record laboratory ambient conditions — temperature 24 °C, relative humidity 45 % RH. Confirm sample quantity (2 pcs) and document sample surface treatment status (/).
- High-Temperature Exposure: Place samples inside the thermal shock test chamber. Set chamber to 60 °C with 80 % relative humidity. Maintain for 2 hours.
- Low-Temperature Exposure: Transition samples to the low-temperature zone. Set chamber to −20 °C. Maintain for 2 hours.
- Total Cycle Storage: Continue alternating high- and low-temperature cycles for a cumulative total storage duration of 72 hours, following the programmed control profile (程序控制图).
- Post-Test Functional Check: Remove samples from the chamber after completion of all cycles. Power on each sample and verify that lighting illuminates normally (开机灯光正常). Verify that charging function operates normally (充电正常). Inspect all exterior surfaces for appearance anomalies.
- Acceptance Criteria: No appearance defects. Lighting function must be fully operational. Charging function must be fully operational. No structural failures or deformation attributable to thermal stress.
Test Data & Results
| Test Phase / Check Item | Condition | Duration | Observation |
|---|---|---|---|
| High-Temperature Exposure | 60 °C, 80 % RH | 2 hours per cycle | Samples subjected to elevated heat and humidity; no anomalies noted during exposure |
| Low-Temperature Exposure | −20 °C | 2 hours per cycle | Samples subjected to sub-zero cold; no anomalies noted during exposure |
| Total Storage | Alternating thermal shock cycles | 72 hours cumulative | Full programmed cycle profile completed as scheduled |
| Power-On Lighting Check (开机灯光正常) | Post-test, ambient conditions | — | Normal — lighting function operates correctly on both samples |
| Charging Function Check (充电正常) | Post-test, ambient conditions | — | Normal — charging function operates correctly on both samples |
| Appearance Inspection | Post-test, visual | — | No appearance anomalies detected on either sample |
Overall test result: Both samples passed the extreme-environment thermal shock test. No appearance abnormalities were found, and the lighting function showed no failures (样品通过极端环境冲击测试，外观无异常，照明功能无失效).

Frequently Asked Questions
What does the CL6 camping light thermal shock test involve?
The CL6 thermal shock test cycles the camping light between a high-temperature phase (60 °C, 80 % RH, 2 hours) and a low-temperature phase (−20 °C, 2 hours) inside a dedicated thermal shock test chamber, for a cumulative total of 72 hours. After the full cycle, testers verify lighting function, charging function, and exterior appearance.
Did the ETENWOLF CL6 pass the high-low temperature cycle test?
Yes. Both CL6 samples passed. After 72 hours of alternating extreme-temperature exposure, all units powered on normally, lighting operated without failure, charging was fully functional, and no appearance anomalies were detected. The official judgment is Pass (合格).
What temperature range was the CL6 tested to?
The CL6 was tested across a range of −20 °C (low-temperature phase) to 60 °C with 80 % relative humidity (high-temperature phase). This range is designed to simulate extreme cold and hot storage environments a camping light might encounter in real-world use.
Why is periodic thermal shock testing conducted on the CL6?
Periodic thermal shock testing is conducted on a regular verification basis to confirm that the CL6 camping light maintains performance stability and structural integrity when stored or used in extreme temperature environments. The test purpose is to evaluate durability under conditions well beyond typical operating ranges.
