This specification covers poly(vinyl chloride) (PVC) profile wall perforated and nonperforated pipe and fittings, 100 to 1200 mm (4 to 48 in.) nominal inside diameter, for use in nonpressure storm drains, culverts, underdrains, and other subsurface drainage systems providing either soiltight or watertight joints. Industrial waste disposal lines should be installed only with the specific approval of the governing code authority since chemicals not commonly found in drains and temperatures in excess of 60°C (140°F) may be encountered. Pipe and fittings produced to this specification should be installed in accordance with ASTM D2321 and the manufacturer’s recommendation.
