NOCSAE headform used in testing

Why We Use the NOCSAE Head Form: Real-World Helmet Evaluations Backed by Science

When it comes to helmet evaluations, realism matters. That’s why at our Headstrong™ Helmet Shoots, we go beyond traditional methods to demonstrate how helmets perform in real-world conditions. Central to this approach is our use of the NOCSAE head form—a scientifically validated surrogate that closely mimics the human head. 

What Makes the NOCSAE Head Form Different? 

Unlike rigid or clay-based head forms, the NOCSAE (National Operating Committee on Standards for Athletic Equipment) head form is designed to replicate the biomechanics of a human head. It features: 

  • A plastic skull structure
  • Polyurethane flesh-like material
  • A glycerin bladder that simulates brain response to impact 

This head form is widely used by organizations like the NFL and Virginia Tech in their helmet safety evaluations. It’s not just a testing tool—it’s a benchmark for biofidelic accuracy. 

Our Rules of Engagement: Real-World Testing, Real-World Results 

At Headstrong™ Helmet Shoots, we follow a strict set of protocols to ensure our testing is both safe and representative: 

  • Use of the NOCSAE Head Form
  • We shoot helmets on the most biofidelic head form available to simulate how a human head and the helmet would respond to ballistic impact. 
  • Comprehensive Impact Zones 
  • Helmets are shot in the front, left, right, top, and back to demonstrate consistent performance across all critical areas. 
  • Varied Ammunition 
  • We use a range of rounds to show how helmets perform under different velocities and impact energies, from lower-speed threats to high-velocity impacts. 
  • Strict Safety Protocols 
  • Every shoot is conducted under controlled conditions with full adherence to live-fire safety standards. 

Why Not Clay?

Clay head forms are still used in some ballistic standards, but they were originally developed for body armor testing—not helmet evaluation. Their primary value lies in consistency for historical comparisons, not in replicating how a human skull reacts to impact. 

Looking Ahead

We’re also preparing to integrate a load-sensing head form developed by Biokinetics, procured under the PANTHER 7 initiative. This advanced tool will allow us to measure ballistic load transmission with even greater precision. 

Conclusion

Helmet safety isn’t just about passing a test—it’s about protecting lives in the real world. By using the NOCSAE head form and following our Headstrong™ Rules of Engagement, we’re committed to delivering insights that matter, backed by science and grounded in reality.
