INDEPENDENT 3rd PARTY TESTING BY SATRA TECHNOLOGY SATRA TECHNOLOGY CENTRE, UK SATRA is a leading independent testing house based in the UK. All external testing was completed in accordance with ECE 22.05 using a kerbstone anvil at 7.5 m/s. ECE 22.05 is a high speed linear impact test for helmets devised to prevent skull fracture in high impact events. Each of the 10 models of MX helmets were tested in both crown and front-side locations. These tests were then repeated on three separate helmets of the same models. Peak deceleration was noted and a Head Injury Criterion (HIC) score was given for each tested impact. HEAD INJURY CRITERION The Head Injury Criterion (HIC) equation measures the risk of head injury. For helmets this is calculated using acceleration data derived from standard ECE linear drop tests. An impact with a HIC score of 3000 is representative of a 99% probability of severe brain injury. At an impact with a HIC score of 1000 that probability drops to an 18% risk SATRA Impacts Test Locations of severe brain injury and down to 5% at a score of 700. Whilst these calculations are a useful indicator to measure the safety of a helmet, they should not be taken as universal scores. The possibility of sustaining a head injury from a crash is a highly variable event which is unique to the individual impact.

These tests consist of a slider with a 30-degree wedge impacting a highly-instrumented bio-fidelic head (Hybrid III), neck and representative body mass. The tunable drop rig mimics the inertia of the human body which allows accurate representation of a head impact to be replicated. Each of the 10 models of MX helmet was tested firstly RESULTS These graphs show the best traces of all models of helmets tested. The reduction in peak acceleration achieved by the FLY Formula can be seen at high and low impact speeds in the traces of these four graphs, demonstrating that the helmet is working over a wide dynamic range of impacts. FLY Formula Helmet Competitor Helmets HELMET TESTING FOR REAL-WORLD SCENARIOS BY at front-side left (high speed 7.1m/s) followed by backside right (high speed 7.1m/s) and lastly at front-side right (low speed 4.2m/s). The results for both linear and rotational acceleration data were recorded and the peak values noted for reference. These tests were then repeated on three separate helmets of the same models. This testing method used the basis of the test method as described in IRCOBI Conference 2016 paper.* FSL FSR BSR 0 80 120 40 Time Linear Resultant Acceleration (m/s^2) Lower Peak = Better High Speed Impact (7.1 m/s) 0 40 80 Lower Peak = Better Low Speed Impact (4.2 m/s) Linear Resultant Acceleration (m/s^2) Time 0 5000 10000 Lower Peak = Better Low Speed Rotational Impact (4.2 M/s) Time 0 5000 15000 10000 High Speed Rotational Impact (7.1 m/s) Time Lower Peak = Better The FLY Formula Helmet Consistently Performed Amongst the Best for All Impacts Tests. 7 HELMETS GOGGLES RACEWEAR OFFROAD BOOTS PROTECTION YOUTH CASUAL LUGGAGE PROMOTIONAL REFERENCE
