There are a few main elements to the new 22-06 rules. The ,impact, tests – where ,helmets, are dropped onto special ,test, anvils and the ,impact forces, measured by ,test, head forms – will now take place at a wider range of velocities, and at more points on the ,helmet, outer shell (up by 12 to 18 in total).

Helmets: How they Work and What Standards Do
Helmets: How they Work and What Standards Do

For ,impact testing,, the typical ,test, apparatus consists of a rig that drops a helmeted headform in a guided freefall to an anvil on the floor. You strap the ,helmet, on the headform, turn it upside down so the ,helmet, hits the anvil first and drop it onto the anvil. The ,helmet, is oriented before each drop to ,test, it's most vulnerable areas.

Bicycle Helmets: What are their limits?
Bicycle Helmets: What are their limits?

The typical bicycle crash ,impact, occurs at a ,force, level equating to about 1 meter (3 feet) of drop, or a falling speed of 10 MPH. The rider's forward speed before the crash may be considerably higher than that, but the speed of the head closing with the ground, plus a component of the forward speed, less any energy "scrubbed off" in other ways, normally average out at about 10 MPH.
