According to Snell, a capable company has always been able to build a helmet which would satisfy both Snell and DOT standards, but not Snell and ECE 22-05. Larger sized helmets with head sizes of 60 cm and up might be able to meet both Snell and ECE 22-05, but this becomes more difficult for smaller sizes, where it is impossible to meet both sets of requirements.
RX-7 GP はECE SNELL2010両方に通ってる。SHARPの結果もまずまず。 サイドも300以下に抑えられてる。
840 : 774RR[sage] : 投稿日:2011/07/10 11:22:03ID:p1ChlYVl Snell standards don't limit dwell times. I'm told that Dr. George Snively, the man who, more than any other, created the Snell Foundation, disagreed with the whole idea of dwell time as a test criterion. The business of helmets is to extend the duration of the acceleration pulse and to limit the peak g values. Putting limits on the duration seemed kind of counterproductive.
スネルはピークGと加速度の減衰という目的を達成するためには、 G継続時間に制限を加えることは非生産的だと考えている。 (スネルを作ってきたも同然の博士Dr. George Snivelyによる)
