| Parameter | Value |
|---|---|
| Instrument Name | Vibration Testing Machine |
| Test Mode | Random Mode |
| Test Duration | 1 hour |
| Vibration Axes / Direction | X, Y, Z (random) |
| Vibration Frequency | 4 Hz |
| Test Speed (CMP) | 240 G |

Test Procedure
- Pre-test: Inspect all 3 sample units for pre-existing damage. Confirm illumination and charging functions are operating normally. Document pre-test condition with photographs (vibration placement setup and vibration control chart recorded).
- Setup: Place samples in their retail/shipping packaging on the vibration testing machine platform. Orient samples per the test plan for the first axis direction.
- Vibration Test — Axis X: Run random vibration mode at 4 Hz, 240 G CMP, 25.4 mm amplitude for the prescribed time segment within the 1-hour total duration.
- Vibration Test — Axis Y: Reorient samples to Y axis. Repeat random vibration conditions.
- Vibration Test — Axis Z: Reorient samples to Z axis. Repeat random vibration conditions. Total cumulative test time across all axes: 1 hour.
- Post-test Inspection: Remove samples from packaging. Inspect for internal component loosening, structural damage, and surface defects. Verify illumination brightness is normal. Verify charging function is normal.
- Acceptance Criteria: No internal parts loosened; lighting brightness normal; charging function normal; packaging provides effective protection — result recorded as Pass. Any functional failure or loose internal components → Fail.
Test Data & Results
| Check Item | Pre-Test Condition | Post-Test Condition | Result |
|---|---|---|---|
| Vibration Placement Setup | Normal | Normal | Pass |
| Vibration Control Chart | Normal | Normal | Pass |
| Illumination Function | Normal (照明正常) | Normal brightness confirmed | Pass |
| Charging Function | Normal (充电正常) | Normal | Pass |
| Internal Component Loosening | None | No loosening detected | Pass |
Observations: All 3 sample units passed the simulated transport vibration test. No internal components were found loose after testing. Illumination brightness remained normal. The packaging was confirmed to effectively protect the product throughout the test duration across all three axes (X, Y, Z) in random vibration mode.

Frequently Asked Questions
What does ISTA-2A cover and why is it used for the CL6 lantern?
ISTA-2A (International Safe Transit Association Procedure 2A) is a standardized protocol for testing packaged products that weigh 68 kg (150 lb) or less. It simulates the mechanical stresses — including random vibration and drop shocks — that a product is likely to encounter throughout a typical distribution cycle. It is used for the CL6 to confirm that the retail packaging provides adequate protection during road, rail, or air freight transit before the product reaches consumers.
What does the random vibration mode mean in this test?
Random vibration mode means the machine generates vibration energy distributed across a spectrum of frequencies simultaneously, rather than sweeping through a single frequency at a time. This more accurately replicates the complex, unpredictable vibration profile experienced during real-world transport on trucks or conveyor systems. In this test, the CL6 was subjected to random vibration at 4 Hz with a 240 G CMP test speed and 25.4 mm amplitude across all three spatial axes.
What failure modes were being screened for?
The primary failure modes targeted were internal component loosening (e.g., circuit board mounts, battery contacts, LED assembly), loss of illumination function, loss of charging function, and packaging failure that could allow the product to shift or be damaged in transit. All three CL6 samples showed none of these failure modes after the full 1-hour test cycle.
How many samples are required for a valid transport vibration test result?
This test used 3 samples (3 PCS), which is a standard sample size for transport vibration qualification of consumer lighting products. Testing multiple units accounts for unit-to-unit manufacturing variation and provides greater statistical confidence in the result than a single-sample test would.
