Test Procedure
- Pre-Test Inspection: Inspect all 3 T300 samples for appearance integrity and verify normal functional operation before mounting on the vibration table.
- Sample Mounting: Place samples on the vibration testing machine in the designated orientation as shown in test placement photographs.
- Parameter Configuration: Set test mode to Random, frequency to 4 Hz, CMP speed to 240 G, and amplitude to 25.4 mm across axes X, Y, and Z.
- Vibration Execution: Run the vibration test for a continuous duration of 1 hour per ISTA-2A requirements (unpackaged condition).
- Post-Test Inspection: Remove samples from the vibration table and perform full functional check including high-pressure and low-pressure accuracy verification.
- Acceptance Criteria: After testing, product function must be normal — no abnormality in appearance, buttons, or operation; pressure accuracy test must pass at both high and low ranges.
Test Data & Results
| Inspection Item | Requirement | Result |
|---|---|---|
| Post-Test Function Check | Function normal after test | Normal — no abnormality observed |
| Appearance & Button Check | No visible damage or defects | No abnormality in appearance or buttons |
| High & Low Pressure Accuracy Test | Accuracy within specification | Pass (OK) |
| Overall Performance After 1H Vibration | Performance not affected by vibration | Performance unaffected |
Test Result Summary: After the T300 samples completed the 1-hour transport vibration test, performance was not affected by vibration. Appearance, button function, and operation showed no abnormality. Pressure accuracy test passed at both high and low pressure ranges.

Frequently Asked Questions
What does the ISTA-2A vibration test evaluate for the T300 tire gauge?
The ISTA-2A vibration test simulates the mechanical stresses a product experiences during real-world transport. For the T300 digital tire gauge, it verifies that the unit can withstand 1 hour of random vibration across X, Y, and Z axes at 4 Hz frequency, 240 G CMP speed, and 25.4 mm amplitude without any loss of function, appearance damage, or pressure measurement accuracy.
Did the T300 tire gauge pass the transport vibration test?
Yes. All 3 T300 samples passed the ISTA-2A transport vibration test. After 1 hour of continuous random vibration, functional checks confirmed normal operation, no appearance or button abnormalities, and pressure accuracy within specification at both high and low pressure ranges.
Was the T300 tested with or without packaging during the vibration test?
The T300 was tested without packaging (unpackaged condition), which is the more stringent ISTA-2A scenario. This ensures the product’s inherent mechanical robustness is validated independently of any protective packaging materials.
What are the test conditions for the T300 vibration report?
The test was conducted at a laboratory temperature of 22 °C and 55% relative humidity. The vibration machine ran in random mode for 1 hour, covering X, Y, and Z axes simultaneously, at a vibration frequency of 4 Hz, CMP test speed of 240 G, and a vibration amplitude of 25.4 mm, following ISTA-2A requirements.
