ASTM F2135-01(2017)e1

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: F2135 − 01 (Reapproved 2017) F2135 − 01 (Reapproved 2017)An American National Standard
Standard Specification for
Molded Drain, Waste, and Vent (DWV) Short-Pattern Plastic
Fittings
This standard is issued under the fixed designation F2135; 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.
ε NOTE—Fig. X1.1 was editorially corrected in April 2017.
1. Scope
1.1 This specification covers standard fitting geometries for molded short-pattern plastic fittings intended for use in drain, waste,
and vent applications.
1.2 Fittings meeting the requirements of this specification are designed for use with outside-diameter controlled pipe. The body
inside diameter can vary significantly as the wall thickness and outside diameter varies, and therefore, is not suitable for use as
a fitting socket.
1.3 Fittings meeting the requirements of this specification shall be tested in accordance with the applicable requirements of
Specifications D2661 or D2665.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units which are provided for information only and are not considered standard.
1.5 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
requirements prior to use.
1.6 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.

3. Requirements
3.1 Short-pattern fittings shall conform to the geometries as specified in this specification.
3.2 All other dimensions shall be determined in accordance with Test Method D2122.
3.3 The exact outside shape of a short-pattern fitting is determined by the socket dimensions, wall thickness requirements,
waterway, and any other critical dimensions that may be specified.
3.4 Configurations designed as short as possible are acceptable providing that the minimum wall thickness requirements for the
particular nominal size being made is followed.
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.

F2135 − 01 (2017)
3.5 All short-pattern fittings used for drainage and having a 90° directional change (except vent fittings) shall have a pitch of
⁄4 in./ft or 1°12'.
3.6 All short-pattern fittings having tapered threads shall conform and be gaged in accordance with Specification F1498.
3.7 45° Y-Branches:
3.7.1 Short-pattern 45° Y-branches shall not be pitched.
3.7.1.1 When the branch of a short-pattern 45° Y is of a smaller diameter than the main body of the fitting, the internal diameters
of the fitting shall remain constant until they intercept one another.
3.8 One-Quarter Bends:
3.8.1 Short-pattern one-quarter bends shall have a centerline radius of curvature of not less than the nominal pipe size, with the
exception of traps. The centerline radius of curvature shall be measured in accordance with Section 4.
3.9 Sanitary Tees:
3.9.1 Short-pattern sanitary tees and reducing tees shall have a centerline radius of curvature on the side branch of not less than
its nominal size, when measured in accordance with Section 4. The alignment of the side branch shall be so located that the smallest
inside radius of the side branch of the sanitary tee shall meet tangentially with, or within 5 % of, the main bore (see Fig. 1), when
measured in accordance with 4.4.5.
NOTE 1—Refer to Appendix X1 for geometric configurations of some of the fittings being produced. Consult the individual manufacturer for laying
lengths.
4. Test Method for Determining Compliance of Short-Pattern ⁄4 Bends and Sanitary Tees
4.1 Scope:
4.1.1 This test method covers the determination of the centerline radius of short-pattern ⁄4 bends and of the side branch of
short-pattern sanitary tees. A method of determining the alignment of the side branch of short-pattern sanitary tees is also included.
4.2 Significance and Use
4.2.1 Determination of the centerline radius of curvature of short-pattern ⁄4 bends.
4.2.2 Determination of the centerline radius of curvature of the side branch of short-pattern sanitary tees.
4.2.3 Determination of the alignment of the side branch of short-pattern sanitary tees.
