What is the weight of the pointed steel penetrator used in the helmet drop test?

• A. 2.2 pounds
• B. 5 pounds
• C. 1 pound
• D. 3 pounds

Answer: (A)

In helmet penetration testing, a pointed steel penetrator is dropped onto the helmet from a fixed height to simulate a sharp-impact scenario, and the mass of that penetrator is standardized so results are consistent and comparable. The standard mass used is 2.2 pounds (about 1 kilogram), which provides a defined amount of energy when dropped from the specified height. Keeping the mass at this value ensures that every test delivers the same impact energy, allowing helmets to be evaluated fairly against a known benchmark. Using a different weight would alter the impact energy and could unfairly favor or disfavor certain helmets, which is why 2.2 pounds is chosen.
