Standard Specification for Class PS46 Poly(Vinyl Chloride) (PVC) Pipe
|Publication Date:||1 January 2015|
This specification covers the requirements and methods of test for smooth-wall perforated and unperforated poly(vinyl chloride) (PVC) plastic pipe, couplings, and fittings for use in subsurface drainage and surface drainage (culverts) of transportation facilities, where soil support is given to its flexible walls in all applications. It includes provisions for solid wall and solid wall coextruded poly(vinyl chloride) (PVC) plastic pipe. Solid wall coextruded pipe has three layers including a center layer and concentric inner and outer layers. The inner and outer layers are made of virgin or reworked PVC compound and the center layer has external recycled PVC content.
Nominal sizes of 100 to 375 mm in a stiffness class designated as PS46 are included.
Materials, dimensions, flattening, impact resistance, pipe stiffness, extrusion quality, joining systems, perforations, and form of marking are specified.
The following precautionary caveat pertains only to the test method portion, Section 8.8, 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.
