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. Two classes (or pipe stiffness) are included and designated as PS 28 and PS 46. The pipe stiffness, impact resistance, pipe flattening, and solvent cement joint tightness shall be tested to meet the requirements prescribed.
Область применения1.1 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 D 3034. For convenience, some of these fittings are reproduced in .
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. Note 1Type PS 28 and Type PS 46 indicate "pipe stiffness" of 28 and 46, respectively, as outlined in .
Note 2
Pipe and fittings should be installed in accordance with Practice D 2321, or applicable state or local specifications.
