Correct, 2006 IBC Section 712 provides the criteria. The provisions of the exception to 712.3.1 (Pg 94) state; "Where the penetrating items are STEEL, FERROUS OR COPPER PIPES, TUBES OR CONDUITS........."
Through penetrations for walls are provided for at 712.3.1 (pg 94) which references 712.3.1.1 (Assemblies) or 712.3.1.2 (Systems) The provisions of the exception No.1 & 2 of 712.4.1 (Pg 95) state; "Penetrations by STEEL, FERROUS OR COPPER CONDUITS, PIPES, TUBES OR VENTS..............", "Penetrations in a single concrete floor by STEEL, FERROUS OR COPPER CONDUITS, PIPES, TUBES OR VENTS..............", Through penetrations for horizontal assemblies are provided for at 712.4.1 (Pg 95) which references 712.4.1.1 (Assemblies) or 712.4.1.2 (Systems) Additionally where through penetration systems are utilized they must be compatible with the penetrating item.

This exception states that te annular space created by a sprinkler penetration only needs to be covered with a metal escutcheon plate. This, of course, would apply to steel pipe penetrating the rated ceiling assembly. Regards, Salvatore Izzo, P.E.
