GSO ASTM D2321:2024 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.
NOTE 2—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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee
