Designation:D331111An American National StandardStandard Specification forDrain,Waste,and Vent(DWV)Plastic Fittings Patterns1This standard is issued under the fixed designation D3311;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 provides standard fitting geometriesand laying lengths for plastic fittings intended for use in drain,waste,and vent applications.(See Specifications D2661 andD2665.)1.2 Fittings meeting the requirements of this standard speci-fication are designed for use with outside diameter controlledpipe.The inside diameter can vary significantly as the wallthickness and outside diameter varies and therefore is notsuitable for use as a fitting socket.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2.Referenced Documents2.1 ASTM Standards:2D2661 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 FittingsF1498 Specification for Taper Pipe Threads 60 for Thermo-plastic Pipe and Fittings3.Requirements3.1 Fittings shall conform to the geometries and layinglengths as shown in Tables 1-45 and Figs.1-5.Tolerances shallbe 6116in.unless otherwise specified.3.2 Spigot and hub dimensions shall conform to the require-ments of the referencing standard.3.3 The exact outside shape of a fitting is not determined bythe outline drawings shown in this specification but rather bythe socket dimensions,wall thickness requirements,waterway,laying lengths,and any other critical dimensions that may bespecified.3.4 The pitch of sockets for patterns with 90 angles(exceptvent fittings)shall be14in./ft or 1 12 min.3.5 On double reducing sanitary tees,the G2 dimension onbranches will be calculated on the larger size and centerlinesshall remain the same for both branches.3.6 All other dimensions,materials and property require-ments shall be in conformance with the referencing standard.4.Keywords4.1 DWV;fittings;plastic;Schedule 40;thermoplastic1This 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 Aug.1,2011.Published August 2011.Originallyapproved in 1974.Last previous edition approved in 2009 as D3311 09a.DOI:10.1520/D3311-11.2For 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 TABLE 1 Bends,in.(mm)Nominal Pipe Size14BendLong Sweep14Bend18Bend16Bend116BendGGGGG1141916(40)214(57)1(25)78(22)716(11)112134(44)234(70)118(29)1(25)12(13)22516(59)314(83)112(38)1516(33)1116(17)33116(78)4116(103)134(44)11116(43)1316(21)4378(98)41516(125)2316(56)2116(52)1(25)65(min)(127)9(229)2(min)(51)338(86)112(38)86(152).2116(52).112(38)10914(235)A.258(67)A.2316(56)A12101116A.318(79)A.238(60)AA10 in.and 12 in.fittings dimensions are minimumTABLE 2 Bends with Inlets,in.(mm)Nominal Pipe Size14Bend with Low Heel InletLong-Sweep14Bend with Low HeelInletLong-Sweep14Bend with High Heel InletGNGNGNGG3 by 3 by 1123116(78)4316(106)4116(103)434(121).3 by 3 by 23116(78)4716(113)4116(103)41516(125)4116(103)558(143)214(57)4 by 4 by 2378(98)5716(138)41516(125)6(152).D3311 112 TABLE 3 Sanitary Tees,45 Wyes,Combination Wyes and18Bends,in.(mm)Nominal Pipe SizeSanitary Tee Single and DoubleA45 Wye,Single and DoubleCombination Wye and18Bend Single andDoubleGNGJGNGJGNGJ11434(19)1916(40)1116(27)2916(65)716(11)21516(75)1121(25)134(44)118(29)278(73)12(13)338(86)2138(35)2516(59)138(35)358(92)1(25)412(114)311316(46)3116(78)158(41)5(127)118(29)6516(160)4214(57)378(98)178(48)638(162)11316(46)858(219)6312(89)5(127)134(44)8716(214)BB8412(114)6(152)238(60)1134(298)BB10512(140)C91116(246)C2716(62)C13(330)CBB126916(167)C11(279)C278(73)C1538(391)CBBANon-reducing double sanitary tees are for vent use only.BCombination wye and18bend is assembled from two standard fittings.C10 in.and 12 in.fittings dimensions are minimum.D3311 113 TABLE 4 Reducing Sanitary Tees,45 Wyes,Combination Wyes,and18Bends,in.(mm)Nominal Pipe SizeSanitary Tee,Reducing Single and DoubleA45 Wye,Reducing Single and DoubleCombination Wye and18BendReducing Single and DoubleG1G2G3G4G1G2G3G1G2G3112by 114by 1141116(17)B112(38)B11116(43)B11116(43)B112by 114by 1121(25)134(44)134(44)134(44)112by 112by 1141316(21)11116(43)11316(46)1131
