Abstract
This specification covers machine-made fiberglass pipe for use in pressure systems for conveying sanitary sewage, storm water, and many industrial wastes, and corrosive fluids. Both glass-fiberreinforced thermosetting-resin pipe (RTRP) and glass-fiberreinforced polymer mortar pipe (RPMP) are fiberglass pipes. This standard is suited primarily for pipes to be installed in buried applications, although it may be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining and slip-lining and rehabilitation of existing pipelines. The pipe is intended to operate at certain internal gage pressures. The fiberglass sewer and industrial pressure pipe are defined by raw materials in the structural wall (type) and liner, surface layer material (grade), operating pressure (class), and pipe stiffness. Different tests shall be performed in order to determine the following properties of pipe: inside diameter, outside diameter, length, wall thickness, squareness of pipe ends, chemical resistance, soundness, stiffness, hoop-tensile strength, beam strength, longitudinal tensile strength, and longitudinal compressive strength.
Scope
1.1 This specification covers machine-made fiberglass pipe, 8 in. (200 mm) through 156 in. (4000 mm), for use in pressure systems for conveying sanitary sewage, storm water, and many industrial wastes, and corrosive fluids. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. This standard is suited primarily for pipes to be installed in buried applications, although it may be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining and slip-lining and rehabilitation of existing pipelines. Pipe covered by this specification is intended to operate at internal gage pressures of 450 psi (3103 kPa) or less.
Note 1—For the purposes of this standard, polymer does not include natural polymers.
1.2 The values given in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.3 The following precautionary caveat pertains only to the test method portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 2—There is no known ISO equivalent to this standard.

A The cell-type format provides the means of identification and specification of piping materials. This cell-type format, however, is subject to misapplication since unobtainable property combinations can be selected if the user is not familiar with commercially available products. The manufacturer should be consulted.
B For the purposes of this standard, polyester includes vinyl ester resin.
C Based on operating pressure in psig (numerals).
