(Specification)Standard Specification for Large Diameter Corrugated Polyethylene Pipe and Fittings
Standard Specification for Large Diameter Corrugated Polyethylene Pipe and Fittings
SCOPE
1.1 This specification covers requirements and test methods for materials, workmanship, dimensions, perforations, pipe stiffness, elongation, joint separation resistance, quality of extruded polyethylene, brittleness, bond, and marking of corrugated polyethylene (PE) pipe and fittings. It covers nominal sizes 8 in. (203 mm), 10 in. (254 mm), 12 in. (305 mm), 15 in. (381 mm), 18 in. (457 mm), and 24 in. (610 mm).
1.2 This specification covers tubularly extruded, spirally laminated, and rotationally molded corrugated polyethylene pipe.
1.3 The values given in parentheses are provided for information purposes only.
Note 1-Sizes 3 to 6 in. are covered in Specification F 405.
1.4 The following precautionary caveat pertains only to the test method portion, Section 9, 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.
