Test Procedure
- Pre-Test: Record the laboratory environment (temperature 22 °C, humidity 55% RH). Inspect all 3 EV3 samples for appearance and confirm normal power-on and functional operation prior to testing. Document pre-test condition with photographs (vibration placement, control diagram, and test duration setup).
- Mounting: Secure the sample(s) on the vibration testing machine platform in accordance with the ISTA-2A test configuration.
- Vibration Execution: Apply random vibration in all three axes (X, Y, Z) at a frequency of 4 Hz, amplitude of 25.4 mm, and a CMP test speed of 240 G for a continuous duration of 1 hour.
- Post-Test Inspection: After completing the 1-hour vibration cycle, power on each sample and verify: (a) normal start-up and operation, (b) no functional failure, (c) no appearance or button anomalies, (d) normal charging function, and (e) normal inflation accuracy.
- Acceptance Criteria: After testing, the product must power on normally and exhibit no functional failures. Inflation accuracy must remain within specification. Any failure in power-on, function, appearance, or accuracy constitutes a test failure.
Test Data & Results
| Check Item | Pre-Test Status | Post-Test Status | Result |
|---|---|---|---|
| Power-On / Normal Start-Up | Normal | Normal — no anomaly after 1-hour vibration | Pass |
| Overall Function | Normal | Performance unaffected by vibration | Pass |
| Appearance & Buttons | Normal | No appearance or button anomalies | Pass |
| Charging Function | Normal | Charging normal | Pass |
| Inflation Accuracy | Normal | Inflation accuracy normal (OK) | Pass |
Test Result Summary: After 1 hour of vibration testing, all 3 EV3 tire inflator samples powered on and operated without anomaly. Performance was not affected by vibration. Appearance and button functions were normal. Inflation accuracy test result: OK.

Frequently Asked Questions
What does the ETENWOLF EV3 vibration test verify?
The ETENWOLF EV3 transportation vibration test verifies the product’s resistance to the mechanical stresses experienced during shipping and real-world use. It confirms that after 1 hour of random vibration across all three axes (X, Y, Z) at 4 Hz and 25.4 mm amplitude, the EV3 inflator powers on normally, retains accurate inflation readings, and shows no damage to appearance or buttons.
Which standard was used for the EV3 vibration test?
The EV3 vibration test was conducted to the ISTA-2A test class, which is an internationally recognized protocol for evaluating packaged products under simulated transportation environments including random vibration.
What were the vibration test parameters for the EV3 inflator?
The EV3 vibration test used the following parameters: test mode — random; duration — 1 hour; axes — X, Y, and Z; vibration frequency — 4 Hz; test speed (CMP) — 240 G; vibration amplitude — 25.4 mm. The laboratory environment was maintained at 22 °C and 55% relative humidity throughout the test.
Did all EV3 samples pass the vibration test?
Yes. All 3 EV3 tire inflator samples passed the ISTA-2A vibration test. After the 1-hour random vibration cycle, every sample powered on without anomaly, charging function was normal, inflation accuracy remained within specification, and no appearance or button defects were observed. The official judgment is Pass.
