Test Procedure
- Pre-Test: Record the initial appearance and functional status of all 3 HB3 samples. Confirm laboratory environment is 22 °C / 55% RH.
- Setup: Mount samples on the vibration testing machine in the specified orientation. Photograph the vibration placement and vibration control chart before starting.
- Vibration Test: Run random vibration for 1 hour across axes X, Y, and Z at 4 Hz, 240 G CMP, and 25.4 mm amplitude per ISTA-2A requirements.
- Post-Test Inspection: Power on each sample and verify normal startup function. Inspect appearance for any damage. Verify charging function operates normally.
- Acceptance Criteria: After testing, the product must power on normally with no functional failure. Appearance and charging must show no anomalies.
Test Data & Results
| Inspection Item | Pre-Test Status | Post-Test Status | Result |
|---|---|---|---|
| Sample Placement / Vibration Setup | Normal | Normal | Pass |
| Vibration Control Chart | — | Within parameters | Pass |
| Appearance | No anomaly | No anomaly | Pass |

Frequently Asked Questions
What test standard was used for the HB3 hair dryer vibration test?
The HB3 vibration test was conducted according to the ISTA-2A standard, which evaluates a product’s ability to withstand transportation and use-environment stresses through random vibration across multiple axes.
What were the key vibration test parameters for the ETENWOLF HB3?
The test ran in random mode for 1 hour across X, Y, and Z axes at a vibration frequency of 4 Hz, test speed of 240 G (CMP), and a vibration amplitude of 25.4 mm. The laboratory environment was maintained at 22 °C and 55% RH throughout.
Did the ETENWOLF HB3 hair dryer pass the transportation vibration test?
Yes. All 3 HB3 samples passed the 1-hour ISTA-2A random vibration test. Post-test inspection confirmed normal power-on function, no appearance anomalies, and normal charging function across all units.
How many samples were tested in the HB3 vibration report?
Three (3) PCS of the HB3 hair dryer were tested, all under the same conditions, and all received a Pass judgment (Report No. 2025051901, dated 2025-05-19).
