Test Equipment & Setup
| Parameter | Value |
|---|---|
| Instrument Name | Vibration Testing Machine |
| Test Mode | Random Mode |
| Test Duration | 1 hour |
| Vibration Axes | X, Y, Z (random direction) |
| Vibration Frequency | 4 Hz |
| Test Speed (CMP) | 240 G |
| Vibration Amplitude | 25.4 mm |
Test Procedure
- Pre-test inspection: Verify all 3 FL2 flashlight samples are in normal working condition — power on, confirm illumination function, inspect exterior for pre-existing damage.
- Sample placement: Position samples on the vibration table according to the vibration placement layout (振动摆放) as documented in the test pictures.
- Parameter configuration: Set the vibration testing machine to random mode, frequency 4 Hz, amplitude 25.4 mm, speed CMP 240 G, axes X / Y / Z.
- Vibration run: Execute the random vibration cycle for a continuous duration of 1 hour across all three axes.
- Post-test inspection: Power on each sample, confirm normal startup and illumination with no functional failure; inspect exterior appearance for abnormalities; verify charging function operates normally.
- Acceptance criteria: After testing, the product must power on normally with no functional failure. Any sample that fails to illuminate or shows functional defects is recorded as a failure.

Frequently Asked Questions
What does the ETENWOLF FL2 flashlight vibration test cover?
The test subjects the FL2 flashlight to 1 hour of random-axis (X, Y, Z) vibration at 4 Hz, 240 G CMP, and 25.4 mm amplitude per the ISTA-2A standard. It simulates stresses the product encounters during transportation and normal use to confirm structural and functional integrity.
Did the FL2 flashlight pass the ISTA-2A vibration test?
Yes. All 3 FL2 flashlight samples passed. After completing the full 1-hour vibration run, each unit powered on normally, illumination function was confirmed intact, and charging operated without any abnormality.
What vibration parameters were used in the FL2 transport test?
The test used a random vibration mode with a frequency of 4 Hz, a test speed of 240 G CMP, and an amplitude of 25.4 mm. All three spatial axes (X, Y, Z) were included in the random direction cycle, run continuously for 1 hour at 22 °C and 55% RH.
What are the acceptance criteria for the FL2 vibration test?
A sample passes if, after completing the vibration cycle, it powers on normally and all functions — including illumination and charging — operate without failure. Any sample showing functional defects or structural damage is recorded as a fail.
