| Sample Quantity | 3 pcs |
| Test Reason | ■ New Product |
| Test Objective | Evaluate the durability of the prototype unit when stored under extreme temperature environments |
| Laboratory Environment | Temperature: 24 °C; Humidity: 45% RH |
Test Equipment & Setup
| Item | Detail |
|---|---|
| Instrument Name | Constant Temperature and Humidity Testing Machine (恒温恒湿试验机) |
| Test Condition 2.1 — High Temperature | 60 °C, Humidity 80% RH, Duration 72 hours |
| Test Condition 2.2 — Low Temperature | −20 °C, Duration 72 hours |
| Test Condition 2.3 — Total Storage | 144 hours combined |
| Test Condition 2.4 | Functional test performed after storage |
| Test Class / Level | — (not specified) |
Test Procedure
- Pre-Test: Confirm laboratory environment is at 24 °C and 45% RH. Record initial functional state of all 3 sample units. Verify button functions and inflation accuracy baseline.
- High-Temperature Phase: Place all 3 samples inside the constant temperature and humidity chamber. Set chamber to 60 °C and 80% RH. Maintain conditions for 72 continuous hours.
- Low-Temperature Phase: After the high-temperature phase, transition the chamber to −20 °C (no humidity specification). Maintain conditions for 72 continuous hours. Total storage time reaches 144 hours.
- Post-Conditioning Recovery: Remove samples from chamber. Allow units to return to laboratory ambient conditions (24 °C, 45% RH) before functional evaluation.
- Functional Test: Power on each unit and verify normal start-up behavior. Test all button functions for any abnormality. Measure low-pressure inflation accuracy and high-pressure inflation accuracy on each sample.
- Acceptance Criteria: After 144 hours of high/low temperature storage, all samples must power on normally, all button functions must operate without failure, and inflation accuracy must remain within specification. Any functional failure results in a Fail verdict.
Test Data & Results
| Evaluation Item | Observation / Result |
|---|---|
| Power-On After High/Low Temperature Conditioning | Normal — units powered on without anomaly (高低温后开机正常) |
| Button Functions | All button functions normal; no abnormalities detected |
| Low-Pressure Inflation Accuracy (低压打气精度) | Normal |
| High-Pressure Inflation Accuracy (高压打气精度) | Normal |
| Overall Functional Status After 144 h Storage | No functional failure; performance consistent with pre-test baseline |
Test images recorded during the test: In-chamber testing photos (测试中), program control chart (程序控制图), and post-conditioning power-on verification images were documented in the original report.
Summary: All 3 S7 samples completed the 144-hour high/low temperature storage test inside the climate chamber. After conditioning, each unit powered on normally, all button functions were intact, and both low-pressure and high-pressure inflation accuracy readings were normal.

Frequently Asked Questions
What temperature range was the ETENWOLF S7 tested to for storage conditions?
The ETENWOLF S7 tire inflator was tested across a storage range of −20 °C (low temperature) to +60 °C at 80% relative humidity (high temperature). Each phase lasted 72 hours, for a combined total storage duration of 144 hours.
Did the S7 tire inflator pass the high/low temperature storage test?
Yes. All 3 sample units passed. After 144 hours of combined extreme-temperature storage, every unit powered on normally, all button functions operated without failure, and both low-pressure and high-pressure inflation accuracy remained within normal parameters.
What equipment was used to conduct the temperature storage test on the S7?
A constant temperature and humidity testing machine (恒温恒湿试验机) was used. The laboratory ambient conditions during testing were maintained at 24 °C and 45% RH.
Why is high/low temperature storage testing important for tire inflators?
Tire inflators are frequently stored in vehicles, garages, and outdoor environments where temperatures can swing from below freezing to extreme summer heat. High/low temperature storage testing verifies that internal components — including electronics, seals, and pressure sensors — remain functional after prolonged exposure to these conditions, ensuring the device works reliably when needed.
