Test Bat — Air

Title: Test Bat Air – Pneumatic Consistency & Performance Verification Protocol 1. Objective The Test Bat Air procedure ensures that pneumatic or air-assisted test bats meet required standards for internal pressure retention, impact response, and structural integrity prior to deployment in controlled hitting environments. 2. Equipment Required

Pneumatic test bat (prototype or production sample) Digital pressure gauge (0–30 PSI range, ±0.1% accuracy) Air compressor with moisture filter Leak detection spray or ultrasonic leak detector Impact test rig (calibrated pendulum or linear actuator) Data logging system

3. Pre-Test Setup

Inspect bat surface for visible defects or seam irregularities. Seal the bat’s air inlet valve and pressurize to 12 PSI (standard test pressure). Allow 5 minutes for temperature stabilization. Test Bat Air

4. Air Retention Test

Record initial pressure (P0). Isolate bat from air supply and monitor pressure every 15 minutes for 2 hours. Acceptable loss: ≤0.3 PSI over 2 hours. If pressure drops exceed tolerance, perform leak detection at joints, valve core, and barrel seams.

5. Dynamic Air Response Test

Re-pressurize bat to 12 PSI. Mount on impact test rig. Deliver 50 controlled impacts at 60 mph ball speed. Measure post-impact pressure recovery within 5 seconds. Passing criteria: Pressure returns to ≥11.8 PSI before next impact.

6. Thermal Air Behavior Test (Optional)

Condition bat at 40°C and 5°C for 1 hour each. Measure pressure variation. Air volume adjustment may be required to maintain equivalent stiffness across temperatures. Title: Test Bat Air – Pneumatic Consistency &

7. Safety & Pass/Fail Criteria

No sudden decompression or valve ejection during testing. No surface cracking or audible air escape. Bat passes if all pressure and impact criteria are met.
