These requirements cover polyvinyl chloride (PVC) pressure pipe, couplings, and gaskets for use in underground, nonpotable fire service systems and
connections to such systems. The pipe is either the distribution or transmission type.
Distribution pipe covered by these requirements is designated as Classes 100, 150, and 200 for rated working pressures of 100, 150, and 200 psig (0.69, 1.03,
1.38 MPa), respectively, and has a nominal inside diameter of 4 to 12 inches.
Transmission pipe covered by these requirements is designated as Pressure Rating 100, 125, 160, 165, 200, and 235 for rated working pressures of 100, 125,
160, 165, 200, and 235 psig (0.69, 0.86, 1.10, 1.14, 1.38, and 1.62 MPa), respectively, and has a nominal inside diameter of 14 to 36 inches.
Requirements for the installation and use of PVC pressure pipe and couplings are specified in the Standard for the Installation of Private Fire Service Mains and
their Appurtenances, NFPA 24-1995.
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.
