Test Procedure
- Pre-Test Inspection: Power on each sample and verify normal startup, functional operation, and high/low pressure inflation accuracy. Document baseline appearance and performance.
- Sample Mounting: Mount the S7 inflator on the vibration testing machine table in the designated orientation for the first axis.
- Vibration Execution: Apply random-mode vibration at 4 Hz frequency, 25.4 mm amplitude, 240 G CMP for a cumulative total of 1 hour across X, Y, and Z axes.
- Axis Rotation: Reorient the sample as required to cover all three random directions (X, Y, Z) within the test duration.
- Post-Test Inspection: Power on each sample, check for normal startup, inspect appearance for any deformation, cracking, or loose components, and verify high/low pressure inflation accuracy.
- Acceptance Criteria: After the 1-hour vibration test, the product must power on normally with no functional failure; high/low pressure accuracy must be within specification; no abnormal appearance defects permitted.
Test Data & Results
| Check Item | Acceptance Criterion | Sample 1 | Sample 2 | Sample 3 | Result |
|---|---|---|---|---|---|
| Normal Power-On | Powers on without issue after test | Pass | Pass | Pass | Pass |
| Functional Operation | No functional failure | Pass | Pass | Pass | Pass |
| Appearance Inspection | No abnormal appearance / button damage | Pass | Pass | Pass | Pass |
| High/Low Pressure Inflation Accuracy | Accuracy within specification, inflation normal | Pass | Pass | Pass | Pass |
Observations: After 1 hour of random-axis transport vibration testing, all 3 S7 new samples showed no abnormality in appearance, buttons, or functions. High and low pressure inflation accuracy tested OK on all units. The vibration placement, vibration control chart, and test duration were recorded photographically during the test. Pre-test performance showed no anomalies.
Test Result Statement: After the S7 tire inflator new samples underwent 1 hour of transport vibration testing, there were no abnormalities in appearance, button functions, and high/low pressure accuracy testing passed.

Frequently Asked Questions
What does the ISTA-2A vibration test verify for the ETENWOLF S7 tire inflator?
The ISTA-2A transport vibration test verifies that the S7 tire inflator can withstand the mechanical stresses encountered during shipping and handling. It confirms that the product powers on normally, shows no functional failure, and maintains accurate high and low pressure inflation performance after 1 hour of random-axis vibration at 4 Hz, 25.4 mm amplitude, and 240 G CMP.
Did the ETENWOLF S7 pass the transport vibration test?
Yes. All 3 S7 samples passed the ISTA-2A transport vibration test conducted on 2025-03-11. After 1 hour of random-mode vibration across X, Y, and Z axes, every unit powered on normally, showed no appearance or button abnormalities, and delivered accurate high and low pressure inflation. The official verdict is Pass.
What vibration parameters were used in the S7 transport vibration test?
The test used a vibration testing machine in random mode with the following parameters: frequency of 4 Hz, vibration amplitude of 25.4 mm, test speed of 240 G (CMP), test duration of 1 hour, and random direction across X, Y, and Z axes. The laboratory environment was maintained at 22 °C and 55% RH.
How many S7 samples were tested and who approved the report?
Three S7 tire inflator samples (new product units) were tested. 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 and the report number is 2025031101.
