b'rp rotational impact testHELMETSCurrently, nearly each research group active within helmet safety has its own definition of helmet safety.An official Standard that allows measuring and quantifying oblique impact and combines the insight of the different experts would provide a more objective framework of about helmets safety.On this purpose, CEN (THE EUROPEAN COMMITTEE FOR STANDARDIZATION), through the Technical Committee TC 158 which is dedicated to the head protection and the eight Working Groups currently active under it, is developing a method for measuring the absorption of energy from oblique or normal impactsThe Working Group directly focused on that is known as the CEN TC 158 / Working Group 11.At Rudy Project we are committed to develop products aiming to the highest level of safety, exceeding the current requirements set by international Standards, such as the CE or CPSC norms.Today more than ever our goal is to go even further by overpassing also the RP ROTATIONAL IMPACT TEST.The RP ROTATIONAL IMPACT TEST is an internal protocol adopted by Rudy Project, in cooperation with accredited and notified bodies, to test and measure the performance of the helmets against rotational impacts; it takes inspiration from CEN, from ECE 22.06 (a new standard for motorcycle helmets) and it is based on real accident data and scientific sources.The RP ROTATIONAL IMPACT TEST 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.*The RP ROTATIONAL IMPACT TEST is a RUDY PROJECT internal protocol to test and measure the performance of the RUDY PROJECT helmets against rotational impacts. This test has not been adopted by CEN or by its Working Group CEN TC 158 / Working Group 11.RP ROTATIONAL IMPACT TEST oblique tests @ 45 on X,Y and Z axis impact speed 6 m/s,BRIC 0,68grade 80 closed-coat aluminum oxide abrasive paperheadform nominal coefficient of friction 0,3wireless system: triaxial accelerometer + n. 3 ARSHeadform: EN960 serieMeasurements: Peak of rotational acceleration, Peak of linear acceleration, HIC, BRIC ( 0,68)WINGDREAM, REBEL, EGOS, NYTRON, SPECTRUM, VENGER, VENGER CROSS, PROTERA+SUCCESSFULLY PASSED RP ROTATIONAL IMPACT TEST75'
