There's all kinds of info on helmet testing and different standards. I can't find any on how time affects a helmets ability to protect the wearer.
Yeah I know. My head is worth a lot more than the price of a new helmet so just go buy one. I'm gonna. But this is more about curiosity. My HJC is due for replacement but I can see nothing obviously wrong with it.
Does anyone know of any research of this kind or have any experience with helmets past their "best before" date?
3 to 5 years is the lifespan of a helmet that has been in use (sweat, direct sunlight, etc.) however some of the more expensive one (Aria & Shoei) have a lifespan of 8 years. This is due to the components used start braking down. Imagine having 2 brand new cars exactly the same. Park one in a garage and one in the direct Florida sunlight. Come back in 5 years and look at the differences in paint work.
Of course once a helmet has been in an accident, it should be replace. Also depending on how high of a drop the helmet has, it could compromise the internal structure.
A lot of times you will see brand new helmets that are heavily discounted. There is nothing wrong with them other than they are not the latest and greatest (read: color / graphics change) models.

It's my opinion 5 years has always been the defacto product life of a helmet. That's why they have a date code on the inside. Motor officers got a new helmet every 5 years.
Not to disagree with the so-called helmet "lifespan", I've yet to read of someone dying or suffering a serious head trauma from an out-dated helmet.
Logic dictates that if there is a helmet "lifespan" there would also be a helmet "out-date".
Does anyone know where that "out-date" is located? I've looked at all eleven of my helmets and haven't found an out-date yet.
Just sayin.......

You're right, the expired date of a helmet could be a fallacy by helmet manufacturers to sell you a new helmet.
Sun, heat, cold, ozone, sweat, body oils and stink could break down the shell, padding and Styrofoam inside the bucket. No law says you can't wear a 25 yr old helmet. Only one way we will know for sure if the old bucket is any good. Kinda like wearing a frayed seat belt.

Not really sure about the life span of a helmet but a few years ago I wanted a certain style of helmet, not realizing at the time that the padding inside the helmet wasn't the best and it was also cheap but it sure looked cool at the time. I replaced that helmet, a couple of months ago, with a better quality helmet because the padding had gotten so thin after wearing it so much that it felt loose and sloppy on my head and that didn't impress me too much. This new helmet should last as long as I do.
