Test Equipment & Setup
| Parameter | Detail |
|---|---|
| Test Object | T500 Tire Pressure Gauge |
| Sample IDs | 1#, 2#, 3# |
| Number of Drop Orientations | 4 |
| Orientation 1 | Back face down (背面朝下) |
| Orientation 2 | Right side down (右侧面朝下) |
| Orientation 3 | Front face down (正面朝下) |
| Orientation 4 | Left side down (左侧面朝下) |
| Drop Surface | Hard flat surface (standard protocol) |
| Evaluation Method | Visual inspection of appearance + functional verification post-drop |
Test Procedure
- Pre-Test: Inspect each sample for pre-existing cosmetic defects and verify normal functional operation. Record initial condition of units 1#, 2#, and 3#.
- Drop 1 — Back Face Down (背面朝下): Hold the unit at the specified drop height with the back face oriented downward. Release without added force and allow free fall onto the hard flat surface. Immediately inspect appearance and test functionality.
- Drop 2 — Right Side Down (右侧面朝下): Repeat the free-fall drop with the right side of the unit facing down. Inspect appearance and function after impact.
- Drop 3 — Front Face Down (正面朝下): Repeat the free-fall drop with the front face (display side) oriented downward. Inspect appearance and function after impact.
- Drop 4 — Left Side Down (左侧面朝下): Repeat the free-fall drop with the left side of the unit facing down. Inspect appearance and function after impact.
- Post-Test: Record results for all four drop orientations per sample. Compare observations against acceptance criteria.
- Acceptance Criteria: No cracks, fractures, or detached components in appearance; all functions operate normally after each drop. Any anomaly in appearance or function constitutes a FAIL.
Test Data & Results
| Drop Date | Sample No. | Drop 1 | Drop 2 | Drop 3 | Drop 4 |
|---|---|---|---|---|---|
| Back Face Down | Right Side Down | Front Face Down | Left Side Down | ||
| 2024-08-01 | 1# | No anomaly in appearance or function | No anomaly in appearance or function | No anomaly in appearance or function | No anomaly in appearance or function |
| 2# | No anomaly in appearance or function | No anomaly in appearance or function | No anomaly in appearance or function | No anomaly in appearance or function | |
| 3# | No anomaly in appearance or function | No anomaly in appearance or function | No anomaly in appearance or function | No anomaly in appearance or function |
Observations: All 12 drop events (3 samples × 4 orientations) produced no observable damage to the housing, display, connectors, or controls. Functional verification after each drop confirmed normal pressure-reading operation across all units. The T500 demonstrates consistent mechanical robustness in all four principal drop orientations tested.
Conclusion
| Field | Detail |
|---|---|
| Result | PASS |
| Standard / Method | Internal 4-orientation drop test protocol |
| Test Conditions | 4 drop orientations per sample; hard flat surface; standard lab environment |
| Samples | 3 units — 1#, 2#, 3# (all passed) |
| Verdict | The ETENWOLF T500 tire pressure gauge meets the mechanical reliability requirements of the drop test. No appearance defects or functional failures were recorded in any of the 12 drop events. |

Frequently Asked Questions
What does the T500 drop test evaluate?
The drop test evaluates the mechanical reliability of the T500 tire pressure gauge by subjecting it to free-fall impacts from four orientations — back face down, right side down, front face down, and left side down. After each drop the unit is inspected for cosmetic damage and tested to confirm all functions operate normally.
How many samples were tested and what were the results?
Three production samples (1#, 2#, 3#) were tested. Each sample was dropped four times, once per orientation, for a total of 12 drop events. Every single event resulted in no anomaly in appearance or function, meaning all three units achieved a clean PASS across the full test matrix.
Which drop orientation is most demanding for a tire pressure gauge?
Front face down (正面朝下) is generally considered the most demanding orientation for a gauge because it directly impacts the display screen and the pressure inlet nozzle — the two most sensitive components. The T500 passed this orientation on all three samples without any display damage or functional degradation.
Where can I find the companion drop test report for the T500?
The full four-orientation drop test raw data is documented in the sibling sheet 跌落试验报告 (Drop Test Report) from the same Excel workbook. See the Related Products section below for a direct cross-link.
