3. Terminology
3.1 Definitions—Definitions are in accordance with Terminology F412 and abbreviations are in accordance with Terminology
D1600, unless otherwise specified. The abbreviation for polyethylene is PE.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 closed profile (CP)—a profile wall pipe wall construction that presents an essentially smooth internal and external surface
that is formed by a solid core wall pipe with thermoplastic pipe reinforcement, or by the spiral winding of a structural thermoplastic
profile.
3.2.2 extrusion welding—a joining technique that is accomplished by extruding a molten polyethylene bead between two prepared
surface ends.
3.2.3 gravity flow, n—for the purposes of the specification, gravity flow means a piping system flowing less than full, except during
storms or high flow conditions when the system may become surcharged in which case, the system is subject to temporary internal
hydrostatic pressure that is limited to joint capabilities. See Section 7.
3.2.4 open profile (OP)—a profile wall pipe wall construction that presents an essentially smooth internal surface with a ribbed
or corrugated external surface. The wall of the pipe is reinforced with round or rectangular profiles.
3.2.5 profile wall—a pipe wall construction that presents an essentially smooth surface in the waterway but includes other shapes,
which can be either solid or hollow, that help brace the pipe against diametrical deformation (see Fig. 1).
3.2.6 ring stiffness constant (RSC)—the value obtained by dividing the parallel plate load in pounds per foot of pipe length, by
the resulting deflection, in percent, at 3 % deflection. The ring stiffness constant (RSC) that is used in this specification to classify

pipe is a measure of the pipe’s deformation resistance to diametrical point loading, such as is experienced during handling and
installation. A pipe should resist these loads sufficiently well to allow its installation to prescribed deflection limits.
4. Classifications and Uses
4.1 Uses—The requirements of this specification are intended to provide pipe suitable for underground or overground gravity flow
drainage of sewage, surface water, and industrial waste.
NOTE 2—Industrial waste disposal lines should be installed only upon the specific approval of the governing code, or other authority, and after determining
the suitability of the product under the anticipated environment, temperature, and other end-use conditions. Users should consult the manufacturer for
the required product information.
4.2 Classifications—This specification covers PE profile wall pipe products made in six standard ring stiffness constant (RSC)
classifications, namely 40, 63, 100, and 160, 250 and 400. These are referred to as RSC 40, RSC 63, RSC 100, RSC 160, RSC
250 and RSC 400.
NOTE 3—Other RSC classifications may be supplied, as agreed upon between the purchaser and the manufacturer, provided that such product complies
in every other respect with the applicable dimensional tolerances and testing requirements of this specification.
4.3 Pipe Ends and Joining Systems: Joints intended for sewer applications shall be watertight. They shall meet the requirements
of Test Method D3212. Joints intended for drainage applications shall be sand/silt tight.
4.3.1 Bell and Spigot, Gasketed Type—The bell and spigot are formed on the pipe or welded to the pipe. Seal is made by a gasket
compressed between the spigot and billed ends of the pipe (see Fig. 2).
4.3.2 Bell and Spigot, Extrusion Weld Type—The bell and spigot are formed on the pipe or welded to the pipe. Seal is made by
extrusion welding (3.2.2) of the bell and spigot pipe ends (see Fig. 3).
4.3.3 Heat Fusion—Heat fusion joints are in accordance with Practice F2620. Seal is made by joining molten pipe ends under
controlled temperature and pressure (see Fig. 4).
4.3.4 Plain End Extrusion Weld—Seal is effected by extrusion welding prepared plain ends of the pipe (see Fig. 5).
4.3.5 Spiral Wound Plain End—Seal is made by extrusion welding on the ID side, or the OD side, or both, of the prepared plain
ends at the termination of the spiral winding. (see Fig. 6).
4.3.6 Electrofusion Bell & Spigot—The seal is made by electrofusion joining through an integral electrofusion device built into
the spigot end of the pipe. The spigot is inserted into the socket (or bell) and current applied to the contacts.
4.3.7 Electrofusion Coupling—The seal is made by electrofusion joining through a separate electrofusion coupling or fitting. The
electrofusion fitting may be an enlarged OD coupler, a reduced ID coupler, or an equal OD/ID internal coupler.
4.3.8 Threaded Joint—The pipe ends are threaded with male and female threads on opposite ends of the pipe. These joints are
considered to be sand/silt tight. (see Fig. 7)
4.3.9 External Coupler—Only couplers supplied or recommended by the manufacturer shall be used.
4.3.10 Other—Where these connections are impractical or undesirable because of space, layout, or other requirement, joining
methods such as flanging, restrained integral connectors, and others may be used. Methods proposed should be evaluated by the
engineer for suitability.
