| Laboratory Environment | Temperature: 28 °C; Humidity: 65% RH |
Test Equipment & Setup
| Item | Parameter | Value |
|---|---|---|
| Instrument | Name | Vibration Testing Machine |
| Test Mode | Pattern | Random Mode |
| Test Duration | Time | 1 H |
| Vibration Direction | Axes | X, Y, Z (Random) |
| Vibration Frequency | Frequency | 4 Hz |
| Test Speed | CMP | 240 G |
| Vibration Amplitude | Amplitude | 25.4 mm |
Test Procedure
- Pre-Test: Inspect all 3 samples for appearance defects and confirm normal power-on and full functionality before vibration exposure. Record baseline condition.
- Setup: Mount samples on the vibration testing machine table in the specified orientation. Connect vibration control instrumentation.
- Execution: Run random vibration mode simultaneously across X, Y, and Z axes at 4 Hz frequency, 240 G CMP speed, and 25.4 mm amplitude for a continuous duration of 1 hour.
- Post-Test Inspection: Power on each sample and verify normal startup. Inspect appearance for any cracks, deformation, or loose parts. Test charging function.
- Acceptance Criteria: After the 1-hour vibration test, the product must power on normally with no functional failure. Post-test appearance and charging function must show no abnormality.
Test Data & Results
| Check Point | Pre-Test | Post-Test |
|---|---|---|
| Appearance | Normal | No abnormality |
| Power-On Function | Normal | Normal — no failure |
| Charging Function | Normal | Normal (charging confirmed) |
| Vibration Placement | — | Confirmed per vibration control chart |
| Overall Performance | — | Performance unaffected by vibration throughout 1-hour test |
Observations: All 3 samples completed the full 1-hour random vibration test process. Post-test visual inspection showed no appearance defects. All samples powered on normally and charging functioned correctly. No functional failures were recorded across any sample.
Test Result Statement: Samples passed the 1-hour vibration test process; performance was not affected by vibration and no functional failure occurred.

Frequently Asked Questions
What does the ISTA-2A vibration test standard require?
ISTA-2A (International Safe Transit Association Procedure 2A) is a packaged-product test protocol designed to simulate the mechanical hazards encountered during distribution and transportation. It specifies random vibration profiles across multiple axes to evaluate whether a product and its packaging can withstand real-world shipping stresses without damage or functional failure.
Why does the S3 inflator undergo vibration testing?
Vibration testing verifies that the S3’s internal components — motor, PCB, battery connections, and housing — remain structurally intact and fully functional after the mechanical stresses typical of road, rail, and air freight. Passing this test gives confidence that the product will arrive at customers in working condition and will continue operating reliably in field use.
What criteria must the S3 meet to pass this test?
After completing the full 1-hour random vibration cycle across X, Y, and Z axes, each sample must: power on normally, show no functional failure, exhibit no appearance defects (cracks, deformation, loose components), and charge correctly. All three samples in this test met every criterion.
How many samples were tested and what was the outcome?
Three production samples of the S3 cordless tire inflator were subjected to the test. All three passed with no failures recorded, confirming the design’s robustness for transportation and operational environments.
