Test Procedure
- Pre-Test: Record laboratory ambient conditions (Temperature: 24°C, Humidity: 45% RH). Inspect and document sample appearance for 3 pcs of HB1 air pump. Photograph samples before testing (程序控制图 / pre-test images captured).
- High Temperature Phase: Place samples in the constant temperature and humidity testing machine. Set chamber to 60°C and 80% RH. Maintain for 2 hours.
- Low Temperature Phase: Transition chamber to −20°C. Maintain for 2 hours.
- Cycle Continuation: Repeat high/low temperature cycles as required to complete a total cumulative storage duration of 72 hours.
- Post-Test Functional Check (2.4): Remove samples from chamber. Allow samples to return to ambient conditions. Power on each sample and verify normal operation. Verify charging function operates normally.
- Post-Test Appearance Inspection: Examine all 3 samples for any physical deformation, cracking, discoloration, or surface anomalies.
- Acceptance Criteria: No appearance abnormalities. All functional checks (power-on, charging) pass. Verdict recorded as Pass (合格), Fail (不合格), or Reference (参考).
Test Data & Results
| Check Item | Condition | Requirement | Result / Observation |
|---|---|---|---|
| Pre-Test Appearance | Ambient (24°C, 45% RH) | No defects | Normal — images captured (测试前程序控制图) |
| High Temperature Exposure | 60°C, 80% RH, 2 hours | No deformation, no failure | Completed |
| Low Temperature Exposure | −20°C, 2 hours | No cracking, no failure | Completed |
| Total Storage Duration | Cumulative cycling | 72 hours | Completed |
| Post-Test Power-On | Ambient recovery | Normal start-up | PASS — 开机正常 (Power-on normal) |
| Post-Test Charging | Ambient recovery | Charging functions correctly | PASS — 充电正常 (Charging normal) |
| Post-Test Appearance | Ambient recovery | No appearance anomalies | PASS — No anomalies observed |

Frequently Asked Questions
What is a high/low temperature storage cycle test?
A high/low temperature storage cycle test exposes a product to alternating extremes of heat and cold while in a non-operating (stored) state. The purpose is to evaluate whether materials, joints, and components can withstand thermal expansion and contraction without cracking, deforming, or losing function. In this test, the HB1 was subjected to 60°C at 80% RH and −20°C in repeated cycles over a total of 72 hours.
Why is the total storage duration set to 72 hours?
72 hours is a commonly used benchmark in consumer electronics environmental testing because it provides sufficient time to stress-test material bonds, plastic housings, and internal electronics across multiple thermal cycles. It balances thoroughness with practical test turnaround time.
What does it mean that charging and power-on were tested after the cycles?
Post-test functional checks — specifically power-on and charging — are the primary pass/fail indicators. If the internal battery, charging circuit, or control board were compromised by thermal stress, these functions would fail. A normal result on both checks confirms the HB1’s core electronics remained intact through the extreme temperature exposure.
What standard does this test follow?
The report references BTK internal form number BTK-R-Q-087A/1 and was conducted under BTK’s internal test protocol. The test conditions (60°C/80% RH for high temp, −20°C for low temp, 72-hour total storage) are consistent with common consumer product environmental durability requirements. The specific external standard cited is not listed in this report.
