Test Procedure

Pre-Test: Confirm laboratory environment is within specification — temperature 22 °C, humidity 55% RH. Inspect and document the appearance and functional status of all 3 T300 samples before any drop.
Setup: Mount the single-arm drop testing machine. Set drop height to 120 cm. Identify the 5 target drop faces for each sample.
Drop Execution: Perform Drop 1 (Face 1), Drop 2 (Face 2), Drop 3 (Face 3), Drop 4 (Face 4), and Drop 5 (Face 5) sequentially, releasing the unit in free fall from 120 cm onto a hard surface for each face.
Post-Test Inspection — Appearance: Examine the housing for cracks, deformation, or breakage. Verify all snap-fit structural components are intact with no cracking or detachment.
Post-Test Inspection — Function: Power on each sample and verify normal operation. Perform an accuracy test and confirm readings are within specification.
Documentation: Record all observations, photograph pre-drop and post-drop conditions, and record the pass/fail verdict.

Acceptance Criteria: After all 5 drops from 120 cm, the product housing must show no cracking or deformation, all structural snap-fits must remain intact, the unit must power on normally, and the accuracy test must return normal results.

Test Data & Results

Drop No.	Drop Face	Drop Height	Appearance After Drop	Snap-Fit / Structure	Power-On Function	Accuracy Test
Drop 1	Face 1	120 cm	No cracking or deformation	No cracking or detachment	Normal	Normal
Drop 2	Face 2	120 cm	No cracking or deformation	No cracking or detachment	Normal	Normal
Drop 3	Face 3	120 cm	No cracking or deformation	No cracking or detachment	Normal	Normal
Drop 4	Face 4	120 cm	No cracking or deformation	No cracking or detachment	Normal	Normal
Drop 5	Face 5	120 cm	No cracking or deformation	No cracking or detachment	Normal	Normal

Observations: After all five 120 cm bare-unit drops, the T300 housing showed no breakage or deformation. All structural snap-fit components remained fully engaged with no cracking or separation. The unit powered on normally after each drop, and the accuracy test confirmed readings were within acceptable limits. Pre-drop and post-drop photographs documented these findings.

Summary result recorded in report: T300 sample 100 cm bare-unit drop — no appearance damage or deformation, structural snap-fits show no cracking or detachment, power-on function normal, accuracy test normal. (Note: the report narrative states 100 cm while the test conditions state 120 cm; the test conditions table value of 120 cm is treated as the governing specification.)

Frequently Asked Questions

What drop height was used in the T300 tire gauge drop test?

The T300 Digital Tire Gauge was tested at a drop height of 120 cm using a single-arm drop testing machine, covering 5 faces with one drop per face for a total of 5 drops.

Did the T300 pass the bare-unit drop test?

Yes. All 3 T300 samples passed the 120 cm 5-face bare-unit drop test. Post-drop inspection confirmed no cracking or deformation of the housing, no detachment of structural snap-fits, normal power-on function, and normal accuracy readings.

What acceptance criteria apply to the T300 drop test?

The product must show no cracking or deformation of the outer housing, all snap-fit structural components must remain intact without cracking or separation, the unit must power on normally, and the accuracy test must return normal results after all drops.

Who approved the T300 drop test report?

The report was approved by Mai Shaoqiang, reviewed by Zhang Ronggui, and the test was conducted by Li Guanghua. The form number is BTK-R-Q-087A/1.
