SHARP works by using a guided fall test based upon the BSI 6658 conventional developed in 1985 and utilizes the ECE headforms, that is intriguing, as they say that a guided fall allows minimize energy dissipation due to helmet rotation within the ECE test.

Retention system test: just like what we observed in DoT and ECE, Snell also subjects its helmets to retention program testing.
