JSP Atlantic Goggle

OK. Let's look at another impact test, this time on the very popular Atlantic Goggle.
A couple of things to look out for: watch for flexing in the body of the goggle as the impact made by the 6mm ball bearing is dissipated across the body, creating very little transitional force on the user's face. Secondly, look at the effect on the polycarbonate lens. You can obviously see the dent made by the ball bearing, but there is no cracking, and there is no damage to the rest of the goggle itself, because of the way the energy has been absorbed.

JSP Mk3 Helmet Penetration Test

In this video, we have a close up view of the JSP Mk3 Helmet. We've seen impact tests in earlier posts and we've also seen the effect the test weight has on a certain member of the Cucurbitaceae family (watermelon - I was trying to be clever).
Here we can see the 3kg 'spiked' weight, which has fallen from a static point 1 metre above the test subject...
