1. Scope
1.1 This specification covers the requirements for smooth- wall perforated and nonperforated poly(vinyl chloride) (PVC) plastic pipe and couplings for use in subsurface drainage systems of highways, airports, and similar applications in nominal sizes of 4, 6, and 8 in. and in pipe stiffnesses (PS) that are designated as Type PS 28 and Type PS 46 in accordance with its minimum pipe stiffness. 1.2 Molded fittings for use with highway underdrain pipe are in accordance with Specification D3034. For convenience, some of these fittings are reproduced in Annex A1. 1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. N OTE 1—Type PS 28 and Type PS 46 indicate “pipe stiffness” of28 and 46, respectively, as outlined in 11.1. N OTE 2—Pipe and fittings should be installed in accordance with Practice D2321, or applicable state or local specifications. 1.4 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 The following safety hazards caveat pertains only to the test methods portion, Section 11, of this specification: This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
7. Requirements
7.1 Workmanship—The pipe shall be homogeneous throughout and essentially uniform in color, opacity, density, and other properties. The inside and outside surfaces shall be semimatte or glossy in appearance (depending on the type of plastic) and free of chalking, sticky, or tacky material. The surfaces shall be free of excessive bloom, that is, slight bloom is acceptable. The pipe walls shall be free of cracks, holes, blisters, voids, foreign inclusion, or other defects that are visible to the naked eye and that may affect the wall integrity. Holes deliberately placed in perforated pipe are acceptable. Bloom or chalking may develop in pipe exposed to direct rays of the sun (ultraviolet radiant energy) for extended periods and consequently these requirements do not apply to pipe after extended exposure to direct rays of the sun. 7.2 Dimensions and Tolerance: 7.2.1 Outside Diameter—The outside diameter and toler- ances shall meet the requirements ofTable 4 when measured in accordance with Test Method D2122. The tolerances for out-of-roundness shall apply to pipe prior to shipment. 7.2.2 Wall Thickness—The actual wall thickness of pipe shall be the wall required to meet the physical requirements of this specification but not less than that shown in Table 4 when measured in accordance with Test Method D2122. 7.2.3 Length—Laying length shall be 20 ft (6.1 m) (or as mutually agreed upon between the purchaser and the manufac- turer). A tolerance of 61 in. (625 mm) shall be permitted. 7.2.4 Perforations—Perforated pipe shall be perforated in accordance with Table 5. The perforations shall be approxi- mately circular and cleanly cut. The spigot end, and bell, of belled-end pipe may be unperforated for a length equal to the depth of the socket or shoulder, or both. 7.2.5 Integral Bell Dimensions—Integral bell dimensions of pipe, bends, and sweeps shall comply with Table 1. Elasto- meric seal joints shall meet dimensions recommended by the manufacturer.
