Standpipe vs. Riser
(OP)
The 6" line that enters the building vertically through the slab is called what? I have always considered it a riser however someone else is arguing it's a standpipe.

Contractors will call it all a riser, but most of the Fire Department reviewers I've dealt with know the difference.
RE: Standpipe vs. Riser
Stookeyfpe is correct.
As per NFPA-13 clause 3.5.9 (2010 ed.), Riser is the vertical supply pipes in a sprinkler system.
As per NFPA-14 clause 3.3.11 (2010 ed.), Standpipe is the system piping that delivers the water supply for hose connection, and for sprinklers on combined system, vertically from floor to floor.
