ASTM F891-07

1.1 This specification covers coextruded poly(vinyl chloride) (PVC) plastic pipe with a cellular core and concentric inner and outer solid layers, and 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.

1.2 The function of this specification is to provide standardization of product-technical data and serve as a purchasing guide.

1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. The notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

Note 1 - All the pipe series covered by this specification are permitted to be perforated or belled for joining by solvent cement or belled for joining by an elastomeric seal (gasket). Because this pipe is OD controlled, the inside diameter will vary, and therefore, the pipe ID is not suitable for use as a socket.

Note 2 - This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications, but does not address venting of combustion gases.

1.4 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.

1.5 The values stated in inch-pound units are to be regarded as the standard.

Note 3 - Specifications related to this specification are as follows: D 2665, D 2729, D 3034, F 512, F 758, and F 789.
