T Ratings -0, 1 and 2 Hr (See Item 2)
SECTION A -A
1. Wall Assembly -The 1 or 2 hr fire rated gypsum wallboard/stud wall
assembly shalt be constructed of the materials and in the manner
specified in the individual U300 or U400 Series Walt and Partition Designs
in the UL Fire Resistance Directory, and shall include the following
construction features:
A. Studs -Watt framing may consist of either wood studs or steel
channel studs. Wood studs to consist of nom 2 by 4 in. lumber spaced
16 in, OC. Steel studs to be min 3-1/2 in. wide and spaced max 24 in.
OC.
B. Wallboard, Gypsum* -Thickness, type, number of layers and fasteners
as required in the individual Wall and Partition Design. Diam of
opening shall be 7/8 in. larger than the outside diam of nonmetallic
pipe or conduit (Item 2).
The hourly F Rating of the firestop system is equal to the hourly
fire rating of the wall assembly in which it is installed.
2. Through Penetrants -One nonmetallic pipe or conduit to be installed
either concentrically or eccentrically within the firestop system. The
annular space for nom 1-1/4 in. diam and smatter between the pipe or
conduit and periphery of opening shalt be min 0 in. (point contact) to
max 7/8 in. The annular space for pipe or,conduit greater than nom
1-1/4 in. diam between the pipe or conduit and periphery of opening
shall be min, 1/2 in. to max 1 in. Pipe or conduit to be rigidly supported
on both sides ofwall assembly. The following types and sizes of
nonmetallic pipes or conduits may be used: _
A. Polyvinyt-Chloride (PVC) Pipe -Nom 2 in. diam (or smatter) Schedule
40 solid core PVC pipe for use in closed (process or supply) or vented
i
(drain, waste or vent) piping g system.
B. Chlorinated Polyvinyl Chloride (CPVC) Pipe -Nom 2 in. diam (or
smaller) SDR17 CPVC pipe for use in closed (process or supply) or
vented (drain, waste or vent) piping systems.
C. Polyvinyl Chloride (PVC) Pipe -Nom 3 in. diam (or smaller) Schedule
40 solid core PVC pipe for use in closed (process or supply) piping
system.
D. Chlorinated Polyvinyl Chloride (CPVC) Pipe=Nom 3 in. diam (or
smaller) SDR17 CPVC pipe for use in closed (process or supply) piping
systems.
E. Rigid Nonmetallic Conduit++ -Nom 3 in. diam (or smatter) Schedule
40 PVC conduit installed in accordance with Article 347 of the
National Electrical Code (NFPA No 70).
F. Electrical Nonmetallic Tubing (ENT)++ -Nom 1 in. diam (or smatter)
ENT formed of PVC, installed in accordance with Article 331 of the
National Electrical Code (NFPA No, 70).
See Rigid Nonmetallic Conduit (DZKT) and Electrical Nonmetallic
Tubing (FKHU) in UL Construction Materials Directory for names of
manufacturers.
G. Acrylonitrile Butadiene Styrene (ABS) Pipe -Nom. 4 in. diam (or
smaller) Schedule 40 solid core or cellular core ABS pipe for use in
closed (process or supply) or vented (drain, waste or vent) piping
systems.
The hourly T Rating is dependent on the hourly rating of the wall
assembly, the pipe or conduit size and whether the pipe is
intended for use as a closed or vented system, as shown in the
following table.
Nom Pipe Wall Assembly Closed (c) Or T Rating
Diam In. Rating Hr Vented (v) Hr
1/2 to 3 1 c 1
1/2 to 1-1/4 1 v 1
1/2 to 1-1/4 2 c 2
1/2 to 1 1/4 2 v 1
2 1 y 0
2 2 v 0
3. Fill, Void or Cavity Materials *-Caulk or Putty- Min thickness of 5/8
in. and 1-1/4 in. of caulk or putty for 1 and 2 hr rated wall assemblies,
respectively, applied within annulus between pipe or conduit and periphery
of the opening, flush with both surfaces of watt assembly. At the point
contact location between pipe or conduit and gypsum wallboard, a min
1/2 in. diam bead of caulk or putty shall be applied at the pipe or
conduit/wallboard interface on both surfaces of watt assembly.
