ASTM D3311-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM 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.
Designation: D3311 − 17 (Reapproved 2021) D3311 − 22 An American National Standard
Standard Specification for
Drain, Waste, and Vent (DWV) Plastic Fittings Patterns
This standard is issued under the fixed designation D3311; 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.
1. Scope*
1.1 This specification provides standard fitting geometries and laying lengths for plastic fittings intended for use in drain, waste,
and vent applications. (See Specifications D2661 and D2665.)
1.2 Fittings meeting the requirements of this standard specification are designed for use with outside diameter controlled pipe. The
inside diameter of pipe can vary significantly as the wall thickness and outside diameter varies and therefore is not suitable for use
as a fitting socket.
1.3 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 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.
2. Referenced Documents
2.1 ASTM Standards:
D2661 Specification for Acrylonitrile-Butadiene-Styrene (ABS) Schedule 40 Plastic Drain, Waste, and Vent Pipe and Fittings
D2665 Specification for Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings
F1498 Specification for Taper Pipe Threads 60° for Thermoplastic Pipe and Fittings
3. Requirements
3.1 Fittings shall conform to the geometries and laying lengths as shown in Tables 1-45 and Figs. 1-5. Tolerances shall be 6 ⁄16
in. unless otherwise specified.
3.2 Spigot and hub dimensions shall conform to the requirements of the referencing standard.
3.3 The exact outside shape of a fitting is not determined by the outline drawings shown in this specification but rather by the
socket dimensions, wall thickness requirements, waterway, laying lengths, and any other critical dimensions that may be specified.
This specification is under the jurisdiction of ASTM Committee F17 on Plastic Piping Systems and is the direct responsibility of Subcommittee F17.63 on DWV.
