I was having a hard time trying to articulate what *I* thought they would be and so I googled around a bit and found this
link. I think it does a pretty good job of explaining (I have no relationship with the Johner Institute). I don't know how many common specifications have been established but in all the googling, I ran across this
RAPS article talking about the common specifications established for reprocessing single use devices.
Hopefully between the 2 items, that gives you a better idea.
