Test Procedure

  1. Pre-Test Preparation: Record product name, manufacturer, sample quantity, and laboratory ambient conditions (24°C, 45% RH). Confirm all 3 samples are in normal condition before testing.
  2. High-Temperature Phase: Place samples inside the constant temperature and humidity testing machine. Set chamber to 80°C with 80% relative humidity. Maintain for 2 hours.
  3. Low-Temperature Phase: Immediately transition samples to −20°C environment. Maintain for 2 hours.
  4. Cycle Repetition: Repeat high-temperature and low-temperature phases alternately for a total cumulative storage duration of 72 hours.
  5. Post-Test Functional Check: Power on each sample to verify normal startup and operation.
  6. Appearance Inspection: Inspect lens (镜片) for cracks or damage; inspect cable compartment (线材仓) for moisture ingress; inspect overall appearance for anomalies.
  7. Acceptance Criteria: No functional failure; normal power-on operation confirmed; no appearance defects. Result recorded as Pass (合格) / Fail (不合格) / Reference (参考).

Test Data & Results

Observation Item Finding
During Test — Chamber Testing in progress inside constant temperature and humidity chamber (恒温恒湿试验箱)
Program Control Diagram Cycle program control chart (程序控制图) used to govern temperature transition sequence
Power-On Function Normal power-on and energization confirmed (开机通电正常)
Lens Condition No damage to lens (镜片无破损)
Cable Compartment Moisture present in cable compartment (线材仓有水份) — noted as observation
Overall Test Result Samples passed thermal cycling test under extreme high and low temperature conditions; no appearance abnormality; no functional failure (样品在极端高低温环境条件下通过温度循环测试,外观无异常,功能无失效)

Note: Moisture was observed in the cable compartment (线材仓) after the humidity phase. All samples nonetheless achieved normal power-on operation, satisfying the acceptance criteria for functional integrity.

Frequently Asked Questions

What temperatures were used in the ETENWOLF S4 SUP Pump thermal shock test?

The test used two extreme temperature phases: a high-temperature phase at 80°C with 80% relative humidity lasting 2 hours, and a low-temperature phase at −20°C lasting 2 hours. The cycle was repeated over a total storage duration of 72 hours inside a constant temperature and humidity testing machine.

Did the ETENWOLF S4 SUP Pump pass the cold-hot thermal shock test?

Yes. All 3 samples passed the thermal shock cycling test. After completing the full 72-hour cycle sequence, every unit powered on normally with no functional failure and no appearance defects, earning an overall verdict of Pass (合格).

Was any damage found on the S4 SUP Pump after thermal cycling?

No structural damage was found. The lens showed no cracking or breakage. Moisture was observed in the cable compartment following the high-humidity phase, but all units still achieved normal power-on function, which is the primary acceptance criterion for this test.

What standard or test class applies to the ETENWOLF S4 thermal shock report?

The test was conducted as a new-product qualification evaluation (新产品) against an internal BTK requirement specifying normal power-on function with no failure after exposure to extreme temperatures. The form number is BTK-R-Q-087A/1. No external standard designation (such as IEC or ISO) was assigned in this report.
