Test Procedure

The test followed the ISTA 2A protocol, which simulates the vibration profile encountered during road, rail, and air freight transportation. Three ETENWOLF S7 units in retail packaging were placed on the vibration platform and secured in their shipping orientation.

  1. Pre-test inspection — Each unit was powered on and verified for normal operation, button responsiveness, display function, and inflation accuracy at both high-pressure and low-pressure settings.
  2. Vibration exposure — The platform ran continuous random vibration at 4 Hz with 240G CMP acceleration and 25.4 mm amplitude for 60 minutes. Direction was randomized across X, Y, and Z axes throughout the cycle.
  3. Post-test inspection — Each unit was removed from the platform and inspected for cosmetic damage (cracks, loose parts, deformation). Units were then powered on and retested for button function, display operation, and high/low pressure inflation accuracy.

Acceptance criteria: all units must power on normally, retain full button functionality, show no cosmetic damage, and pass high-pressure and low-pressure inflation accuracy checks.

Test Data & Results

Check Item Sample #1 Sample #2 Sample #3
Appearance / Cosmetic Damage No damage No damage No damage
Power-On Normal Normal Normal
Button / Key Function Normal Normal Normal
Display Function Normal Normal Normal
High-Pressure Inflation Accuracy Within spec Within spec Within spec
Low-Pressure Inflation Accuracy Within spec Within spec Within spec
Verdict PASS PASS PASS

All three ETENWOLF S7 units showed no degradation after the vibration cycle. The 240G CMP acceleration at 25.4 mm amplitude across all three axes represents a demanding vibration profile that exceeds typical real-world shipping conditions, providing a strong confidence margin for product reliability during distribution.

Key observations:

  • Structural integrity — No cracks, loosened fasteners, or cosmetic deformation on any unit.
  • Functional performance — All buttons responded correctly; power-on sequence completed without error.
  • Inflation accuracy — Both high-pressure and low-pressure modes maintained calibration within factory specification, confirming the internal pressure sensor and valve assembly are adequately secured against vibrational displacement.

Frequently Asked Questions

Did the ETENWOLF S7 pass the ISTA 2A vibration test?

Yes. All three ETENWOLF S7 samples passed the ISTA 2A transportation vibration test. After one hour of random vibration at 4 Hz, 240G CMP, and 25.4 mm amplitude across X, Y, and Z axes, every unit powered on normally and maintained inflation accuracy within specification.

What vibration conditions was the ETENWOLF S7 tested under?

The S7 was tested under ISTA 2A conditions: random vibration mode for 1 hour, across all three axes (X, Y, Z), at a frequency of 4 Hz, an acceleration of 240G (CMP), and a vibration amplitude of 25.4 mm. The laboratory environment was 22 °C and 55% RH.

Can the ETENWOLF S7 survive rough shipping conditions?

Yes. The ISTA 2A test simulates vibration encountered during road, rail, and air freight transport. The S7 passed at 240G CMP — a level that exceeds most real-world shipping vibration — with no cosmetic damage and full functional retention, including high-pressure and low-pressure inflation accuracy.
