Designation:F213501(Reapproved 2012)Standard Specification forMolded Drain,Waste,and Vent(DWV)Short-Pattern PlasticFittings1This standard is issued under the fixed designation F2135;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers standard fitting geometries formolded short-pattern plastic fittings intended for use in drain,waste,and vent applications.1.2 Fittings meeting the requirements of this specificationare designed for use with outside-diameter controlled pipe.Thebody inside diameter can vary significantly as the wall thick-ness and outside diameter varies,and therefore,is not suitablefor use as a fitting socket.1.3 Fittings meeting the requirements of this specificationshall be tested in accordance with the applicable requirementsof Specifications D2661 or D2665.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units which are provided for informationonly and are not considered standard.1.5 This standard does not 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 requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2D2122 Test Method for Determining Dimensions of Ther-moplastic Pipe and FittingsD2661 Specification for Acrylonitrile-Butadiene-Styrene(ABS)Schedule 40 Plastic Drain,Waste,and Vent Pipeand FittingsD2665 Specification for Poly(Vinyl Chloride)(PVC)PlasticDrain,Waste,and Vent Pipe and FittingsD2749 Symbols for Dimensions of Plastic Pipe FittingsF1498 Specification for Taper Pipe Threads 60 for Thermo-plastic Pipe and Fittings3.Requirements3.1 Short-pattern fittings shall conform to the geometries asspecified in this specification.3.2 All other dimensions shall be determined in accordancewith Test Method D2122.3.3 The exact outside shape of a short-pattern fitting isdetermined by the socket dimensions,wall thicknessrequirements,waterway,and any other critical dimensions thatmay be specified.3.4 Configurations designed as short as possible are accept-able providing that the minimum wall thickness requirementsfor the particular nominal size being made is followed.3.5 All short-pattern fittings used for drainage and having a90 directional change(except vent fittings)shall have a pitchof14in./ft or 112.3.6 All short-pattern fittings having tapered threads shallconform 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 asmaller diameter than the main body of the fitting,the internaldiameters of the fitting shall remain constant until theyintercept one another.3.8 One-Quarter Bends:3.8.1 Short-pattern one-quarter bends shall have a centerlineradius of curvature of not less than the nominal pipe size,withthe exception of traps.The centerline radius of curvature shallbe measured in accordance with Section 4.3.9 Sanitary Tees:3.9.1 Short-pattern sanitary tees and reducing tees shallhave a centerline radius of curvature on the side branch of notless than its nominal size,when measured in accordance withSection 4.The alignment of the side branch shall be so locatedthat the smallest inside radius of the side branch of the sanitarytee shall meet tangentially with,or within 5%of,the mainbore(see Fig.1),when measured in accordance with 4.4.5.1This specification is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.63 on DWV.Current edition approved Feb.1,2012.Published February 2012.Originallyapproved in 2001.Last previous edition approved in 2007 as F213501(2007).DOI:10.1520/F2135-01R12.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 NOTE1Refer to Appendix X1 for geometric configurations of someof the fittings being produced.Consult the individual manufacturer forlaying lengths.4.Test Method for Determining Compliance of Short-Pattern14Bends and Sanitary Tees4.1 Scope:4.1.1 This test method covers the determination of thecenterline radius of short-pattern14bends and of the sidebranch of short-pattern sanitary tees.A method of determiningthe alignment of the side branch of short-pattern sanitary teesis also included.4.2 Significance and Use4.2.1 Determination of the ce
