When we talk about standards for hockey helmets, I know there are a number of different tests they'll do to see how they withstand a force. When I was playing in the 1970s as a teenager, I was told that they were dropped from six feet with a 10-pound weight in them, or something such as that.
When they test them, is it testing the damage to the helmet, or are there more sophisticated ways now of testing what type of force is transmitted or not transmitted through the helmet?
