B. Rigid Nonmetallic Conduit (RNC)+ — Schedule 40 PVC conduit installed in accordance with the National Electrical Code (NFPA No. 70).
C. Chlorinated Polyvinyl Chloride (CPVC) Pipe — SDR11,13.5 or 21 CPVC pipe for use in closed (process or supply) piping systems.
D. Acrylonitrile Butadiene Styrene (ABS) Pipe — Schedule 40 solid core ABS or cellular core ABS (ccABS) pipe for use in closed (process or supply) or vented (drain, waste or vent) piping systems. Limited for use with nom 2 in. (51 mm) and 3 in. (76 mm) devices (Item 2).

E. Polyvinyl Chloride (PVC-XFR) Pipe — Schedule 40 solid core PVC XFR for use in closed (process or supply) or vented (drain, waste or vent) piping systems.

F. Crosslinked polyethylene (PEX) Tubing — SDR 9 PEX tubing for use in closed (process or supply) or vented (drain, waste or vent) piping system

4. Packing Material — (Not shown) - When penetrant is less than nom 3 in. (76 mm) installed within the nom 4 in. (102 mm) device and less than nom 2 in. (51 mm) installed within the nom 2 in. (51 mm) device, a min 3 in. (76 mm) thickness of min 4 pcf (64 kg/m3) mineral wool batt insulation shall be firmly packed into the annular space between the penetrant and device as a permanent form. The packing material is to be recessed 1-1/2 in. (38 mm) below the top surface of the floor and extend upward a min of 1-1/2 in. (38 mm) above the top surface of the floor. When optional caulk (Item 5) is used, packing material to be recessed from top of device to accommodate the required thickness of caulk.
5. Fill, Void or Cavity Material* — Caulk — (Optional, Not Shown) - Min 1/4 in. (6 mm) thickness for 2, 3, and 4 in. (51, 76 and 102 mm) and min 3/8 in. (10 mm) thickness for 4 in. (102 mm) and 6 in.
