Standard Specification for Type PS-46 and Type PS-115 Poly(Vinyl Chloride) (PVC) Plastic Gravity Flow Sewer Pipe and Fittings (Withdrawn 2004)
SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, joining systems, and a form of marking for Type PS-46 and Type PS-115 poly(vinyl chloride) (PVC) plastic, gravity flow sewer pipe having a minimum pipe stiffness of 46 psi (320 kPa) and 115 psi (790 kPa), respectively, and fittings.
1.2 Pipe and fittings produced to this specification shall be installed in accordance with Practice D2321.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.4 The following precautionary caveat pertains only to the test method portion, Section 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.
WITHDRAWN RATIONALE
This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, joining systems, and a form of marking for Type PS-46 and Type PS-115 poly(vinyl chloride) (PVC) plastic, gravity flow sewer pipe having a minimum pipe stiffness of 46 psi (320 kPa) and 115 psi (790 kPa), respectively, and fittings.
Formerly under the jurisdiction of Committee F17 on Plastic Piping Systems, this specification was withdrawn in July 2004. This specification was withdrawn in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
