Test Procedure
- Pre-test inspection: Visually inspect all 3 HB2 samples for any pre-existing cosmetic defects or functional issues. Document initial condition. Verify laboratory environment is within specified conditions (30 °C, 55% RH).
- Sample placement: Mount samples on the vibration testing machine platform in the standard orientation as shown in test placement photos.
- Configure equipment: Set vibration testing machine to Random Mode, frequency 4 Hz, amplitude 25.4 mm, test speed CMP 240 G, duration 1 hour.
- Execute vibration — X axis: Run the random vibration profile along the X axis for the programmed duration as part of the 1-hour total test cycle.
- Execute vibration — Y axis: Continue random vibration along the Y axis.
- Execute vibration — Z axis: Continue random vibration along the Z axis, completing all three directional exposures within the 1-hour test window.
- Post-test inspection: Remove samples from the test platform. Visually inspect all surfaces for cracks, deformation, or cosmetic damage. Test charging function on each sample. Document all observations.
- Acceptance criteria: Samples pass if appearance shows no abnormalities and charging function operates normally after completion of the full vibration cycle.
Test Data & Results
| Sample | Test Condition | Appearance After Test | Charging Function After Test | Result |
|---|---|---|---|---|
| HB2 #1 | Random, X/Y/Z, 4 Hz, 240 G CMP, 25.4 mm, 1 H, 30 °C / 55% RH | No abnormality | Normal | PASS |
| HB2 #2 | Random, X/Y/Z, 4 Hz, 240 G CMP, 25.4 mm, 1 H, 30 °C / 55% RH | No abnormality | Normal | PASS |
| HB2 #3 | Random, X/Y/Z, 4 Hz, 240 G CMP, 25.4 mm, 1 H, 30 °C / 55% RH | No abnormality | Normal | PASS |
Overall Test Result: HB2 samples maintained stable performance under various vibration and transport environment conditions. No abnormalities were observed in appearance, and charging functioned normally for all three units. Overall judgment: Pass (合格).

Frequently Asked Questions
What does the ISTA-2A vibration test evaluate for the HB2 hair dryer?
The ISTA-2A test simulates the random vibration stresses a packaged or unpackaged product encounters during transport and handling. For the HB2 hair dryer, it verifies that the unit’s structure, cosmetic finish, and electrical functions — particularly charging — remain intact after exposure to multi-axis random vibration at 4 Hz frequency, 240 G CMP, and 25.4 mm amplitude over one hour.
Did all HB2 samples pass the vibration test?
Yes. All three HB2 hair dryer samples passed. After completing the full 1-hour random vibration cycle across X, Y, and Z axes, every sample showed no abnormalities in appearance and charging function operated normally. The official judgment is Pass (合格).
What were the exact vibration test parameters used for the HB2?
The test used a vibration testing machine in Random Mode. Key parameters: frequency 4 Hz, test speed CMP 240 G, vibration amplitude 25.4 mm, test duration 1 hour, random directions X/Y/Z, laboratory temperature 30 °C, and humidity 55% RH.
Why is transport vibration testing important for hair dryers?
Hair dryers contain internal motor assemblies, heating elements, and plastic housings that can develop micro-cracks, loose connections, or cosmetic damage under the repetitive mechanical stress of shipping and logistics. Transport vibration testing to ISTA-2A ensures that products reaching end users are structurally and functionally uncompromised, reducing warranty returns and field failures.
