1、Designation: F 891 07An American National StandardStandard Specification forCoextruded Poly(Vinyl Chloride) (PVC) Plastic Pipe With aCellular Core1This standard is issued under the fixed designation F 891; the number immediately following the designation indicates the year oforiginal adoption or, in
2、 the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers coextruded poly(vinyl chlo-ride) (PVC) plastic pipe wit
3、h a cellular core and concentricinner and outer solid layers, and is produced using a multilayercoextrusion die for nonpressure use in three series: an IPSSchedule 40 series; a PS series with an iron pipe size outsidediameter with varying wall thickness as required for pipestiffness of 25, 50, and 1
4、00; and a sewer and drain series.1.2 The function of this specification is to provide standard-ization of product-technical data and serve as a purchasingguide.1.3 The text of this specification references notes, footnotes,and appendixes which provide explanatory material. The notesand footnotes (ex
5、cluding those in tables and figures) shall notbe considered as requirements of the specification.NOTE 1All the pipe series covered by this specification are permittedto be perforated or belled for joining by solvent cement or belled forjoining by an elastomeric seal (gasket). Because this pipe is OD
6、controlled, the inside diameter will vary, and therefore, the pipe ID is notsuitable for use as a socket.NOTE 2This standard specifies dimensional, performance and testrequirements for plumbing and fluid handling applications, but does notaddress venting of combustion gases.1.4 This standard does no
7、t purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.5 The values stated in inch-pound unit
8、s are to be regardedas the standard.NOTE 3Specifications related to this specification are as follows:D 2665, D 2729, D 3034, F 512, F 758, and F 789.2.
