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.

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.

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.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
