От: Въпрос за каска ...
По въпроса за падналите каски
Шои казват - ако каската падне, донесете я в оторизиран представител да я прегледа да каже дали е чао. Силно ме съмнява да правят някакви по-различни тестове от обстоен преглед на око отвътре и отвън, така че, според мен спокойно всеки може сам да прецени за себе си. Ако корубата няма видими наранявания и отвътре пяната не е деформирана, то каската на главата и щялата газ.
edit - явно шои са сменили съветите... вече казват "Is a crashed / dropped helmet still safe to wear?
Current safety helmets are designed to absorb the energy of an accident by being destroyed. Even a small impact can damage the integrity of the shell or the inner liner. Quite often this damage may be unnoticeable to the untrained eye. Therefore, any helmet involved in an impact should not be used again."

"I dropped my helmet! Do I have to go buy a new one?"
Generally the answer is probably not. Helmets are one-use items, but are quite durable otherwise, at least the ones we certify. Frequent dropping or spiking a helmet on the ground, or other hard surfaces may eventually degrade the helmet's performance. Similarly if the helmet falls to the ground at highway speeds unoccupied, the owner must be aware that some degradation may have occurred. In general, the real damage comes when the helmet contacts an object with a head inside. The Foundation recommends that if you are participating in an activity that requires that you wear a helmet, you avoid hitting stuff with your head. It can be difficult to readily determine if a helmet has been damaged, and the protective capabilities compromised without a thorough inspection by a trained professional. Some manufacturers may provide this service or direct you to these others that can perform these inspections. The Foundation recommends that if you suspect your helmet may be compromised, then replace it. If the helmet has been involved in an impact while in use, replace it.
