Test Overview

Field Detail
Test Title Accessory Air Hose Rotation Test (配套气管旋转测试)
Product No./Name Accessory Air Hose (配套气管)
Model / Type Specification ETENWOLF S0 Portable Bike Pump
Report No. 2025090302
Test Date 2025-09-03
Sample Quantity / No. 2 PCS (S0-1#, S0-2#)
Type of Test ■ Reliability Test (可靠性测试)
Test Standard Internal Standard (内部标准)
Test Purpose Evaluate the reliability and durability of the air hose connector under repeated rotational use
Test Procedure Summary Simulate the user behavior of repeatedly rotating the air hose during actual inflation to predict sample service life
Acceptance Criterion The air hose connector must not detach or leak air during repeated rotation

Test Equipment & Setup

Parameter Detail
Test Equipment Manual rotation (人工旋转)
Ambient Temperature 23 °C
Relative Humidity 60 %
Test Conditions Room temperature and humidity: 23 °C, 60 %RH

Test Procedure

  1. Pre-test: Inspect both sample units (S0-1# and S0-2#) for any pre-existing defects in the air hose connector, tubing, and fittings. Record baseline condition.
  2. Setup: Attach the accessory air hose to the S0 pump unit as it would be used in normal operation. Ensure the test environment is at 23 °C and 60 %RH.
  3. Rotation procedure: Manually rotate the air hose repeatedly, simulating user behavior of twisting and pulling the hose during actual inflation use.
  4. Interval check: Every 500 rotation cycles, perform an inflation test to verify air pressure delivery and check for any audible air leakage at the connector.
  5. Total cycles: Continue rotation until 4,000 cycles are completed for each sample.
  6. Post-test inspection: After 4,000 cycles, perform a final functional check — confirm connector integrity, absence of air leakage, and normal inflation efficiency.
  7. Acceptance criterion: The air hose connector must not detach or exhibit air leakage at any point during or after the 4,000 rotation cycles.

Test Data & Results

Sample No. Number of Test Cycles Issue Description / Observations
S0-1#, S0-2# 4,000 1. No connector detachment and no air leakage after long-duration rotation. 2. Inflation test performed every 500 cycles — no air leakage detected in any interval check. 3. Inflation efficiency remained normal throughout with no air leakage.

Observations: Both sample units completed the full 4,000-cycle rotation sequence without any connector failure or leakage event. All eight periodic inflation checks (at 500-cycle intervals) confirmed consistent sealing performance. The hose and connector showed no signs of functional degradation.

Overall Test Result: The accessory air hose passed the swing/rotation test. Simulating repeated customer movement and pulling of the air hose produced no audible air leakage and no functional failure.

Conclusion

Field Detail
Result ■ PASS (合格)
Standard Applied Internal Standard — connector must not detach or leak during repeated rotation

Frequently Asked Questions

How many rotation cycles did the ETENWOLF S0 air hose complete without failure?

The S0 accessory air hose completed 4,000 full manual rotation cycles without any connector detachment or air leakage. Inflation performance was verified every 500 cycles, and all checks confirmed normal function throughout the entire test.

What does the S0 air hose rotation test measure?

The test evaluates the reliability and durability of the air hose connector under repeated rotational stress, simulating how a user twists and pulls the hose during real-world inflation use. The key pass criterion is that the connector must not detach or leak air at any point during the 4,000-cycle sequence.

What were the test conditions for the S0 air hose rotation durability test?

The test was conducted at room temperature (23 °C) and 60 % relative humidity using manual rotation. Two sample units (S0-1# and S0-2#) were tested, with an inflation leak check performed every 500 cycles to monitor connector sealing performance.

Did the ETENWOLF S0 portable bike pump air hose pass the rotation durability test?

Yes. Both S0 sample units passed the rotation durability test. After 4,000 rotation cycles, neither unit showed connector detachment, air leakage, or any reduction in inflation efficiency. The product received a formal PASS verdict signed off by the tester, reviewer, and approver on 2025-09-03.
