FWIW, SHARP was developed in 2007, first helmets tested in 2008.
RUROC say:
WHAT'S THE BEST MOTORCYCLE HELMET SAFETY RATING?
ECE 22.06 is the most sophisticated road helmet standard, but that is only legally applicable to EU countries. FIM is a slightly more rigorous version of the 22.06 standard, but that is only specific to track riding, and the additional aspects of it are really only relevant to high-speed riding. All of our ATLAS 4.0 motorcycle helmets have achieved the ECE 22.06 safety rating.
Every major market territory has its own respective motorcycle helmet safety certification that needs to be in place in order to legally ride on those roads. Each of these sets of tests and standards shares similarities, but also have some variations that evaluate the helmet in their own unique way.
ECE 22.06 is the standard required for motorcycle helmets in EU countries, it is the most sophisticated road helmet standard to date, with over 10 significantly different types of tests, all of which together make up the approval process.
The track riding specific FIM qualification follows the ECE 22.06 test process very closely, with slight increases to some of the test's limits, aimed at tackling very high-speed riding. This is also the same for the SHARP rating, with the exception that SHARP add a weighting factor to each impact point when calculating the overall performance. This is based on the probability of having an impact on each point, to ensure a statistically enhanced safety evaluation is delivered.
Achieving ECE 22.06 status with ATLAS 4.0 motorcycle helmet was absolutely key to us achieving our safety improvement aspirations, and in fact, we surpassed all the testing requirements by a minimum of more than 20%. Making this full-face helmet by far the safest ATLAS yet!
