Smart manual says the canopy needs "porosity" testing after 20 repacks.
Their wording is a bit confusing
11. POROSITY: Check porosity in the following cases -After 10 uses -After immersion in water once the canopy is dry -After 20 repacks (based on a 6month repack cycle) -After any use in abnormal conditions
1) it is permeability testing - nylon is not porous, that is, it does not absorb water. 2) After immersion? How much immersion? 3) After 20 repacks (based on a 6 month repack cycle) - does that mean 12 years, or 20 repacks, or either or what? 4) No definition of "abnormal condition".
I tried in October of 2009 to get clearer information from them, and to have them clarify the manual, to no avail.
Whatever the tests, it doesn't say this is a life limit. If it passes the test, you should be able to keep using it.
this is a copy and paste of the email i was sent when asking about shelflife of aerodynes prods.
The 12years shelf life applies to both The Smart and Main Canopies.
The Shelf life of the Container is a little more difficult to. Comment. 12 years (as like the canopies) is my general advice, however they can last a lot longer, really because the harness webbings and components see very little load compared to their strength.
But if you have to ask me a safe life for containers, I would again say 12years.
