Pressure Pipe and Couplings, Glass Fiber-Reinforced, for Underground Fire Service

UL 1713

1.1 These requirements cover glass-fiber-reinforced, thermosetting-resin pipe (RTRP) and glass-fiber-reinforced, plastic-mortar pipe (RPMP), and their couplings. The pipe is for use in underground fire service systems and connections to such systems.

1.2 Pipe covered by these requirements is designated as Class 100, 150, 200, 250, or greater for rated working pressures of 100, 150, 200, 250 psig (0.69, 1.03, 1.38, and 1.72 MPa), or higher, respectively, and has a nominal inside diameter of 4 to 60 inches.

1.3 Requirements for the installation and use of RTRP and RPMP pressure pipe and couplings are specified in the Standard for the Installation of Private Fire Service Mains and their Appurtenances, ANSI/NFPA No. 24, and the Standard Practice for Underground Installation of "Fiberglass" (Glass-Fiber-Reinforced Thermosetting-Resin Pipe), ASTM D3839.
