1. Fragment Strength Test: Utilizing Chatillon model LTC load testers with a displacement accuracy of 0.01mm and force accuracy of 0.1gf.

2. Testing Procedures: The metal shrapnel must be aligned vertically with the test head on a hard plane with a vent. This ensures air compression does not affect the strength accuracy.

3. Life Cycle Test: Conducted at room temperature with a test speed of 1-10 times per second to ensure durability up to millions of clicks.
