This specification covers the material, dimensional, and requirements and corresponding test methods for folded poly(vinyl chloride) (PVC) pipes suitable for the rehabilitation of existing nonpressure sewers and conduits, wherein the folded PVC pipe is inserted into, and then expanded to conform to the wall of, the original conduit forming a new pipe-within-a-pipe structure. This specification does not include pipes manufactured from reprocessed, recycled, or reclaimed PVC. Appropriately sampled specimens shall be tested, and shall thereby conform accordingly to specified requirements for flattening resistance, impact strength, stiffness, extrusion quality by acetone immersion and heat reversion, flexural modulus of elasticity, and rounded pipe diameter and wall thickness.

1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, and a form of marking for folded (vinyl chloride) (PVC) pipe for existing sewer and conduit rehabilitation.

1.2 Pipe produced to this specification is for use in non-pressure sewer and conduit rehabilitation where the folded PVC pipe is inserted into and then expanded to conform to the wall of the original conduit forming a new structural pipe-within-a-pipe.

Note 1—An ASTM specification for the installation of folded PVC pipe is under preparation and will be referenced in this specification when published.

1.3 This specification includes pipe made only from materials specified in Section . This specification does not include pipe manufactured from reprocessed, recycled, or reclaimed PVC.

1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are provided for information only.

1.5 The following precautionary statement pertains to the test method portion only, Section 11, 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.
