It tests helmets under oblique impacts that are often seen in real-world data, which produce larger head rotation. It uses a state-of-the-art headform for more accurate and precise helmet testing results.A drop tower designed to match helmet-to-ground characteristics in snow sports is used to test the helmets. We measure linear acceleration and rotational velocity for each impact, which are correlated to concussion risk. We test 6 impact configurations that include 3 impact locations (front, side, and rear) and 2 anvil angles (high and low).

SHARP impact tests. Each model of motorcycle helmet undergoes 30 linear and 2 oblique impact tests in order to achieve a SHARP rating. To complete these 32 tests, a minimum of 7 individual helmet samples, in a range of sizes, are subjected impacts at three speeds (6, 7.5 and 8.5 metres per second) as follows:
The NFL and NFLPA announced the introduction of five new helmets for the 2024 season that tested better than any helmet ever worn in the league, reflecting a significant advancement in helmet safety innovation.

1. Introduction. Bicycle helmets are the primary and most effective strategy for head protection during impacts to prevent traumatic brain injury (TBI) (Hoye, 2018).Contemporary bicycle helmets employ a liner of rigid expanded polystyrene foam (EPS) that dampens the impact, reduces the impact force, and in turn reduces linear and angular head accelerations . Testing was conducted at two impact velocities and at three impact locations for each helmet design. Results were used to test the hypothesis that dedicated rotation-damping systems can significantly improve the effectiveness by which snow sport helmets can mitigate linear and rotational head acceleration and the associated concussion risk .
That data looked back at the helmets tested from 2014 through 2017 and included what data (only two test reports were posted at the time the data was obtained from the NHTSA website) was available .
