Plumbing Code for PEX/CPVC hangers? (talon, J-hook, etc.)

First post here in this forum, so sorry in advance if I'm out of line.

I had a question about the relevant code for PEX/CPVC hangers like talon clamps. Is there specific load requirements in the UPC, IPC, or Canadian NPC for the holding power of these clamps? How can I check to see if these clamps are holding properly and won't come loose over time? I would hate to come back after the drywall is up.

Thanks.
