ASTM D2321-08

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
An American National Standard
Designation:D 2321–05 Designation: D 2321 – 08
Standard Practice for
Underground Installation of Thermoplastic Pipe for Sewers
1
and Other Gravity-Flow Applications
This standard is issued under the fixed designation D 2321; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope*
1.1 This practice provides recommendations for the installation of buried thermoplastic pipe used in sewers and other
gravity-flow applications.These recommendations are intended to ensure a stable underground environment for thermoplastic pipe
under a wide range of service conditions. However, because of the numerous flexible plastic pipe products available and the
inherent variability of natural ground conditions, achieving satisfactory performance of any one product may require modification
to provisions contained herein to meet specific project requirements.
1.2 The scope of this practice necessarily excludes product performance criteria such as minimum pipe stiffness, maximum
service deflection, or long term strength. Thus, it is incumbent upon the product manufacturer, specifier, or project engineer to
verify and assure that the pipe specified for an intended application, when installed according to procedures outlined in this
practice, will provide a long term, satisfactory performance according to criteria established for that application. A commentary
on factors important in achieving a satisfactory installation is included in Appendix X1.
NOTE 1—Specific paragraphs in the appendix are referenced in the body of this practice for informational purposes.
NOTE2—The following ASTM standards may be found useful in connection with this practice: Practice D420, Test Method D1556, Method D2216,
Specification D2235, Test Method D2412, Specification D2564, Practice D2657, Practice D2855, Test Methods D2922, Test Method D3017, Practice
F402, Specification F477, Specification F545, and Specification F913. 2—The followingASTM standards may be found useful in connection with this
practice: Practice D 420, Test Method D 1556, Method D 2216, Specification D 2235, Test Method D 2412, Specification D 2564, Practice D 2657,
Practice D 2855, Test Methods D 2922, Test Method D 3017, Practice F 402, Specification F 477, Specification F 545, and Specification F 913.
NOTE 3—Most Plumbing Codes and some Building Codes have provisions for the installation of underground “building drains and building sewers.”
See them for plumbing piping applications.
1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are
mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
