The binder or the way the atoms are bound? Given enough time and man's folly..Good luck seeing this answer.
It's most likely a liability decision to list an expiration date on life saving equipment. What could possibly change in any ceramic compound without use or exposure to the elements?
I feel like that's part of the explanation date equation.I've worn out a few coffee cups. Just sayin.
OMG… granny's knee-shooters!!The ceramic figure " venus of volni destonice " is thought to be 25000 years old.
It's got some big naturals too.

It's just .22LR mistake… no problem!I feel like that's part of the explanation date equation.
Plates get dropped and bumped plenty.
Your supposed to "replace if dropped " ,but people don't like admitting to little mistakes.
Agreed. If you read between the lines it's a combination of companies covering themselves for liability, and wanting to sell more armor more often. I'm sure there are issues if you wear it every day, expose it to elements and sweat, etc. These are composites of ceramics and other materials. But stored away ceramic plates should have a VERY long lifetime.Good luck seeing this answer.

That article doesn't say any of that, in fact the opposite.Agreed.

Expiration Dates Matter: Why Body Armor Replacement Is Necessary for Your Safety
Congratulations! You just purchased your brand-new body armor or bulletproof vest. Now, you may think you’re set for life, but that’s not the case. This essential piece of equipment has a limited lifespan. There’s an expiration date by which your vest's life-saving components MUST be replaced to...safelifedefense.com
They don't issue you new plates? Just x-ray old ones despite expiration date?I have multiple OIF 1- present ESAPI plates that still pass the x-ray test yearly. My oldest plate (Ceradyne 11-2002) was "sacrificed" two months ago. It stopped multiple 30.06 API. So if never dropped, left sitting in the sun for years, and or abused....you should be fine. Treat them like your life depends on them. I was told long ago in the Army.
Its the military sometimes yes new gear gets issued but unless they're in combat/ airborne/ special operations... usually its a mix of old and newThey don't issue you new plates? Just x-ray old ones despite expiration date?
They do. I was referring to the periodic x-rays for plates that are still "good". I was in SF, they don't issue plates every year. If they are not expired or damaged/dropped, you use them till they fail either expiration or x-ray.They don't issue you new plates? Just x-ray old ones despite expiration date?
A tiny portion of a % they have to. Would you take expired percocet? Ok then. Put your armor on and git out thar!!
