Standard Specification for Coextruded Poly(Vinyl Chloride) (PVC) Plastic Pipe With a Cellular Core
This specification covers coextruded poly(vinyl chloride) plastic pipe with a cellular core and concentric inner and outer solid layers. The pipe is produced using a multilayer coextrusion die for nonpressure use in three series: an IPS Schedule 40 series; a PS series with an iron pipe size outside diameter with varying wall thickness as required for pipe stiffness of 25, 50, and 100; and a sewer and drain series. The pipe shall comply with the minimum wall thickness, outside diameter, length, stiffness, flattening, impact strength, bond strength, and extrusion quality requirements.
