Test Equipment & Setup
| Parameter | Value |
|---|---|
| Instrument Name | Vibration Testing Machine |
| Test Mode | Random Mode |
| Test Duration | 1 H |
| Random Directions | X, Y, Z |
| Vibration Frequency | 4 Hz |
| Test Speed (CMP) | 240 G |

Test Procedure
- Pre-test inspection: Record appearance and functional baseline of both S1 samples. Confirm power-on function is normal and charging is normal.
- Placement: Mount samples on the vibration testing machine platform in the specified orientation (vibration placement as documented in test pictures).
- Vibration test execution: Run the vibration testing machine in Random Mode across all three axes (X, Y, Z) simultaneously for 1 hour at a vibration frequency of 4 Hz, test speed (CMP) of 240 G, and vibration amplitude of 25.4 mm, in accordance with ISTA-2A.
- Post-test inspection: Remove samples from the machine. Inspect appearance for any damage, deformation, or abnormality. Power on each unit and verify all functions operate normally. Verify charging function is normal.
- Acceptance criteria: Power-on function must show no failure (无失效). Appearance and charging function must show no abnormality.
Test Data & Results
| Check Item | Requirement | Result — Sample 1 | Result — Sample 2 | Verdict |
|---|---|---|---|---|
| Power-on Function | No failure after vibration | Normal | Normal | Pass |
| Post-transport Appearance | No abnormality | No abnormality | No abnormality | Pass |
| Charging Function | Charging normal | Normal | Normal | Pass |
| Overall Vibration Control | Stable throughout 1 H random vibration | Stable | Stable | Pass |
Observations: Both samples completed the 1-hour transport vibration test process with stable performance and no functional failure. Post-test appearance and charging function showed no abnormalities, consistent with the test pictures recorded during the vibration placement and vibration control graph phases.

Frequently Asked Questions
What does the ISTA-2A transport vibration test evaluate?
ISTA-2A is a packaged-product transport simulation standard that subjects a product to random vibration across multiple axes to replicate the mechanical stresses encountered during road, rail, or air shipment. It checks whether the product’s functions, structure, and appearance remain intact after realistic transport conditions.
What test parameters were used for the S1 vibration test?
The S1 was tested in Random Mode simultaneously across the X, Y, and Z axes for 1 hour. The vibration frequency was set at 4 Hz, the test speed (CMP) at 240 G, and the vibration amplitude at 25.4 mm. The laboratory environment was maintained at 22 °C and 55 % RH throughout the test.
What acceptance criteria did the S1 need to meet?
The primary acceptance criterion was that the power-on function must show no failure after the vibration test. Additionally, the post-transport appearance must be free of any abnormality, and the charging function must operate normally — all of which the two S1 samples satisfied.
How many S1 units were tested and what was the outcome?
Two S1 portable tire inflator units were subjected to the full 1-hour ISTA-2A random vibration test. Both units passed with stable performance, no functional failure, normal appearance, and normal charging function. The official judgment was Pass.
