Test Equipment & Setup

Parameter Value
Instrument Name Vibration Testing Machine
Test Standard ISTA-2A (Unpackaged)
Test Mode Random Mode
Test Duration 1 H
Axes / Direction Random — X, Y, Z
Vibration Frequency 4 Hz
Test Speed (CMP) 240 G
Vibration Amplitude 25.4 mm

Test Procedure

  1. Pre-Test: Inspect each sample for cosmetic and functional condition; confirm product operates normally before testing begins.
  2. Mounting: Place samples on the vibration testing machine platform per ISTA-2A unpackaged configuration (vibration placement as documented in test pictures).
  3. Parameter Setup: Configure the machine to random mode, set frequency to 4 Hz, amplitude to 25.4 mm, and test speed to 240 G.
  4. Execution: Run vibration test for 1 hour across all three axes (X, Y, Z) in random direction sequence.
  5. Post-Test Inspection: Remove samples from the platform and inspect for cosmetic damage and functional performance.
  6. Acceptance Criterion: Product function must be normal after testing. Any functional anomaly constitutes a failure.

Frequently Asked Questions

What vibration standard was used to test the T300 tire gauge?

The T300 was tested to ISTA-2A in its unpackaged configuration, which is an internationally recognized standard for simulating transportation and use environment stresses on products.

What were the key vibration test parameters for the T300?

The test used random vibration mode across X, Y, and Z axes for 1 hour at a frequency of 4 Hz, a test speed of 240 G (CMP), and a vibration amplitude of 25.4 mm, conducted at 22 °C and 55% RH.

Did the T300 tire gauge pass the vibration test?

Yes. Both samples passed. Post-test inspection confirmed that the T300 digital tire gauge functioned normally with no anomalies detected after completing the full 1-hour random vibration sequence.

Why is vibration testing important for a digital tire gauge?

Digital tire gauges are regularly transported, stored in vehicle gloveboxes, and used in rough environments. Vibration testing verifies that internal electronics, pressure sensors, and display components can withstand real-world mechanical stress without loss of accuracy or function.
