印象之前看到一篇介紹shark安全帽的文章
裡面就強調他能分散衝擊力
不知道snell的測試標準有沒有把這項考慮進去@@
不管是吸收還是分散
只要能達到標準就是過了
只差在方式不同而已
剛爬了shoei的美國官方網站
發現開版引用的資料太舊了
如果看過新版本的M2005測試標準
我相信你不會貼這篇文章
因為SNELL也很有誠意的修改了他們的標準
版主引用的資料只能針對M2000去攻擊
在那次攻擊之後就改版成M2005了
主要改變有兩種
1. Test line is lowered by 10mm in side head and rear head portions.
Test line is a line to specify an area above the line where such requirements as impact absorption and penetration management have to be satisfied at any point. As per drawing below the test line is lowered by 1mm in side head and rear head portions, and as a result, the area to satisfy the requirements is expanded to a lower direction in M2005. There is no change of the test line in forehead portion because it was already lowered in the last revision from M1995 to M2000.
2. The requirement of Peak G is lowered from below 300G to below 290G.
While the requirement of Peak G in impact management test was below 300G in M2000, it become below 290G in M2005
大意是
1.帽體內的測試線下修10MM
2.M2000要求吸收G力到300G以下,M2005要求吸收到290G以下
也就是說,雖然SNELL被抨擊之後很不滿,也隨之回擊,但SNELL也不是閉門造車的機構,最後又把標準再修改的更嚴格
大家不用對這個過時的文章多加揣測
