WG 11

THE NEXT LEVEL OF SAFETY CERTIFICATION

WG11 ROTATIONAL IMPACT PROTOCOL

  • Currently, nearly each research group active within helmet safety has its own definition of helmet safety. A Standard that allows quantifying oblique impact and combines the insight of the different experts would provide a more objective framework of helmets safety. On this purpose, CEN (the European Committee for Standardization) is developing a method for measuring the absorption of energy from tangential (oblique) or normal impacts. This working group is known as the CEN\TC 158 \ Working Group 11. At Rudy Project we are commited to develop products aming to the highest level of safety, exceeding requirements set by international Standards, such as the CE or CPSC norms. Today our goals is to go even further by overpassing a new experimental testing protocol based on real accident datas and scientific sources. The Rudy Project WG11 rotational impact test is a protocol adopted by Rudy Project, in cooperation with accredited and notified bodies, to test and measure the performance of the helmets against rotational impacts. The Rudy Project WG11 “pass-fail” criterion is based on the BRIC (Brain Injury Criterion) value, an algorithm that defines the level of brain injury. This value must be less than 0,68. Several studies infact showed that concussive values of BRIC for humans varied from 0.60, when scaled directly from animal data, to 0.68 when obtained directly from college football players.
