Test Equipment & Setup
| Parameter | Detail |
|---|---|
| Instrument Name | Vibration Testing Machine |
| Test Mode | Random Mode |
| Test Duration | 1 H |
| Random Direction | X, Y, Z |
| Vibration Frequency | 4 Hz |
| Test Speed (CMP) | 240 G |
| Vibration Amplitude | 25.4 mm |
Test Procedure
- Pre-Test: Confirm laboratory environment is at 22 °C and 55% RH. Inspect all 3 samples for any pre-existing appearance defects and document baseline condition. Power on each unit to verify normal operation before testing.
- Sample Placement: Mount samples on the vibration testing machine platform according to the vibration placement diagram (振动摆放).
- Vibration Test Execution: Set the machine to Random Mode across X, Y, and Z axes simultaneously. Configure frequency to 4 Hz, amplitude to 25.4 mm, and CMP speed to 240 G. Run the test for 1 continuous hour.
- Post-Test Inspection: After the 1-hour cycle completes, remove samples from the platform. Power on each unit and verify normal startup and electrical operation. Inspect exterior surfaces for any cracks, deformation, or cosmetic damage. Perform full functional check to confirm no feature failures.
- Acceptance Criteria: After vibration testing, each sample must power on normally, exhibit no functional failure, and show no abnormal appearance. Any failure in power-on, function, or appearance constitutes a Fail result.
Test Data & Results
| Check Item | Sample #1 | Sample #2 | Sample #3 |
|---|---|---|---|
| Power-On After Vibration | Normal | Normal | Normal |
| Functional Operation | No Failure | No Failure | No Failure |
| Appearance After Vibration | No Abnormality | No Abnormality | No Abnormality |
After completing the 1-hour random vibration test, all three S4 SUP pump samples powered on correctly, operated without any functional failure, and showed no appearance anomalies. The vibration control chart (振动控制图) and pre/post-test photographic records confirm consistent performance across all axes.

Frequently Asked Questions
What test standard was used for the ETENWOLF S4 SUP pump vibration test?
The test followed the ISTA-2A standard, which is a widely recognized protocol for evaluating packaged product performance under transportation simulation conditions including random vibration.
What were the vibration test parameters for the S4 SUP pump?
The S4 was tested in random mode across all three axes (X, Y, Z) for 1 hour at a vibration frequency of 4 Hz, an amplitude of 25.4 mm, and a test speed of 240 G CMP, in a controlled environment of 22 °C and 55% RH.
Did the ETENWOLF S4 SUP pump pass the transportation vibration test?
Yes. All 3 samples passed. After the 1-hour vibration cycle, every unit powered on normally, showed no functional failures, and had no visible appearance abnormalities, resulting in a Pass verdict.
Why is transportation vibration testing important for electric SUP pumps?
Electric SUP pumps contain motors, PCBs, and mechanical seals that can be stressed during shipping. ISTA-2A vibration testing simulates real-world transport conditions to confirm the product arrives at customers in full working order without damage from road or freight vibration.
