Test Procedure
- Pre-Test: Record laboratory environment conditions (temperature 22°C, humidity 55% RH). Inspect and document the appearance, function, and accuracy of the 2 T500 samples prior to testing. Confirm samples are packaged per ISTA-2A requirements.
- Setup: Mount the packaged samples on the vibration testing machine. Configure the instrument to Random Mode with X, Y, and Z axis directions enabled.
- Parameter Configuration: Set vibration frequency to 4 Hz, test speed (CMP) to 240 G, and vibration amplitude to 25.4 mm.
- Test Execution: Run the vibration test for 1 hour continuously across all three axes (X, Y, Z) in random mode.
- Post-Test Inspection: After test completion, remove samples from packaging and inspect for any appearance abnormalities. Verify functional performance and measurement accuracy of each sample.
- Acceptance Criteria: After vibration testing, the product appearance must show no abnormalities, and function and accuracy must be normal (Pass).
Test Data & Results

Frequently Asked Questions
What does ISTA-2A mean in this context?
ISTA-2A is a test protocol from the International Safe Transit Association covering packaged products weighing 68 kg or less. It includes vibration and drop tests designed to simulate the hazards products encounter during distribution and transportation. This test was run with the T500 in its retail packaging.
Why are X, Y, and Z axes all tested?
Real-world transport subjects a product to vibration from multiple orientations — vertical (Z), lateral (Y), and longitudinal (X). Testing all three axes in random mode ensures the T500 is evaluated against the full range of stresses it may experience during shipping and handling.
What does a CMP value of 240 G indicate?
CMP (Composite Maximum Peak) of 240 G refers to the peak acceleration level applied during the random vibration profile. This represents a demanding mechanical stress level intended to expose any structural or functional weaknesses in the product or its packaging.
How is the T500 used after passing this test?
The T500 is a digital tire pressure gauge designed for accurate inflation measurement. Passing the ISTA-2A vibration test confirms that the product maintains its structural integrity and measurement accuracy even after the mechanical stresses of shipping, making it reliable for end-user applications.
