NFPA 13 23.1.6.1.2 The transition piece shall be protected against possible damage from corrosive agents, solvent attack, or mechanical damage.
It is generally interpreted to mean you can't use C900 or plastic through the floor. Although I have seen AHJ's approve with a metal sleeve around it up to the transition to steel.

I know that's all I've ever seen, but can C900 PVC pipe be used? I've browsed through the International Plumbing Code and didn't find any discussions about this situation.
