1.1 This specification covers requirements and test methods for coextruded flexible annular, corrugated profile wall polyethylene pipe with an interior liner. It covers nominal sizes 3 in. (75 mm), 4 in. (100 mm), 5 in. (125 mm), 6 in. (150 mm), 8 in. (200 mm), 10 in. (250 mm), 12 in. (300 mm), 15 in. (375 mm), 18 in. (450 mm), and 24 in. (600 mm). 1.2 The requirements of this specification are intended to provide non-pressure (gravity flow) flexible lined annular corrugated polyethylene pipe for subsurface and land drainage systems, such as agricultural or foundations, which do not operate under surcharge pressure heads. NOTE 1--Pipe produced in accordance with this specification is to be installed in compliance with Practices D2321 or F449 based on diameter limitations within the respective standards. Flexible lined annular corrugated polyethylene provides axial flexibility allowing for subsurface installation using tile plows and allows the pipe to be coiled for storage and transport. NOTE 2-Subsurface and land drainage systems pertain principally to non-municipal or private facilities for water table control, storm drainage, and agricultural applications. NOTE 3--Flexible lined pipe provided in coiled lengths will experience distortion or folding in the interior pipe liner which may adversely affect flow characteristics. Contact the pipe manufacturer for hydraulic design guidance for the coiled flexible lined pipe. 1.3 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 The following precautionary caveat pertains only to the test method portion, Section 7, 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.

This proposed new specification will address a new-to-market flexible lined corrugated polyethylene pipe. This product is currently being produced and requires a product standard for manufacturers, specifiers, and users.
