Typical drop speeds are around 6.5m/sec, 7.5m/sec, 8.5m/sec, depending on the test protocol or certification. Sharp uses all those speeds. The drop height is whatever is needed to achieve those speeds in free fall. If you want mph or km/h use google. The video shows ECE/FIM test which is unconstrained. DOT, Snell, and Sharp use guided falls (1 axis).
only scenario where that argument would apply is if you fell directly on top of your head with your entire body vertically positioned above it. otherwise the only weight affecting the helmet would be your head
Testing is voided...Once they cut into the helmet, they destroy any integrity of the helmet..the test is useless-helmets are designed as a total impact area-where forces dissipate thru-out the helmet. I want to know the mph (or Kmh) the helmet is traveling when it hits the bottom of the drop... I dont care about sound of a helmet (I wear earplugs) or wind, I have windshields and never ride over 80 mph
