Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Power Line Swing Test Machine (电源线摇摆测试机) |
| Test Duration | 15 hours continuous |
| Temperature | 23 °C |
| Relative Humidity | 60% |
| Sample Count | 2 PCS (S0-1#, S0-2#) |
Test Procedure
- Pre-Test: Inspect both air hose samples (S0-1# and S0-2#) for any pre-existing damage, deformation, or loose connectors. Record baseline inflation time for each sample.
- Mounting: Secure each air hose sample in the power line swing test machine, replicating the connector interface used during normal inflation operation.
- Swing Test Execution: Run the swing test machine continuously for 15 hours, simulating the repetitive pulling, moving, and bending motions a user applies to the air hose during actual inflation.
- In-Process Monitoring: Observe the hose for audible leakage, visible deformation, cracking, flattening, or connector separation during the test run.
- Post-Test Inspection: After 15 hours, remove samples and inspect for: (a) loss of material elasticity, (b) external flattening or damage, (c) airflow obstruction, (d) connector loosening or detachment, (e) any air leakage.
- Post-Test Inflation Timing: Perform inflation with each sample and record the time to verify that inflation efficiency has not degraded.
- Acceptance Criteria: The air hose passes if: the hose retains elasticity after prolonged bending; no external crushing or damage is observed; airflow is unobstructed and inflation time is normal; the hose-to-pump-head connector has not detached, loosened, or developed leakage; no audible leakage sound is present during simulated use.
Test Data & Results
| Sample No. | Number of Tests / Duration | Issue Description / Observations |
|---|---|---|
| S0-1# & S0-2# | 15 hours | 1. After prolonged bending, the air hose material retained its elasticity and did not lose flexibility. 2. The exterior of the air hose was not flattened or damaged; airflow was unobstructed; inflation efficiency did not decrease; inflation time was normal. 3. The connection between the air hose and the pump head did not detach, loosen, or develop air leakage. 4. Post-test inflation efficiency — S0-1#: 2 min 05 sec / S0-2#: 1 min 47 sec. |
Overall Test Result: The accompanying air hose passed the swing test. Simulating repeated customer pulling and moving of the air hose produced no audible leakage and no functional failure.

Frequently Asked Questions
What does the ETENWOLF S0 air hose swing test evaluate?
The swing test evaluates the reliability and durability of the S0 air hose under repeated bending and pulling, simulating how a user moves the hose during real-world inflation sessions. It checks whether the hose retains elasticity, maintains airflow, and keeps its connector secure after 15 hours of continuous mechanical stress.
Did the ETENWOLF S0 air hose pass the 15-hour swing test?
Yes. Both samples (S0-1# and S0-2#) passed the full 15-hour swing test with no audible leakage, no external damage, no airflow obstruction, and no connector loosening. Post-test inflation times of 2 min 05 sec and 1 min 47 sec confirmed that inflation performance was unaffected.
What equipment is used to conduct the air hose rocking test?
The test uses a dedicated power line swing test machine, which mechanically replicates the repetitive pulling and bending motions applied to the hose during inflation use. The test is conducted at room temperature (23 °C) and 60% relative humidity.
What are the acceptance criteria for the S0 air hose swing test?
The air hose must retain material elasticity, show no external flattening or cracking, maintain unobstructed airflow, keep the pump-head connector firmly attached without leakage, and deliver normal inflation times after 15 hours of repeated bending. Any audible leakage or functional failure constitutes a fail.
