15、DStandardization of cast and wrought solder-joint fittings was initiated in Subcommittee 11 ofAmerican Standards Association (ASA) Sectional Committee A40 on Plumbing Requirementsand Equipment. Development work culminated in publication of ASA A40.3-1941.In 1949, work on these fittings was transferr
16、ed to Sectional Committee B16 of ASA, whichestablished Subcommittee 9 (now Subcommittee J). The first standard developed was approvedas ASA B16.18-1950, Cast Bronze Solder-Joint Fittings. A later joint effort of the Copper and BrassResearch Association and the Manufacturers Standardization Society o
17、f the Valve and FittingsIndustry (MSS) culminated in a standard on wrought fittings, ultimately approved as B16.22-1951.Concurrently, recognizing the need for drainage fitting standards, an MSS task group developedthe standard later approved as ASA B16.23-1953, Cast Bronze Solder-Joint Drainage Fitt
18、ings, anda standard for wrought fittings was initially published as MSS SP-64-1961. A revision of thatstandard was submitted to Subcommittee 9 of B16 and was eventually approved asASA B16.29-1966.A revision was published after reorganization of ASA as the American National StandardsInstitute (ANSI)
19、as ANSI B16.29-1973. In this edition, shorter solder cups were specified in largersizes, since strength to contain pressure is not a factor. In 1979, Subcommittee I (formerly 9,now J) added metric dimensional equivalents and made other minor improvements. That revisionwas approved by ANSI, after app
20、roval by the Committee and secretariat organizations, asANSI B16.29-1980.In 1982, American National Standards Committee B16 was reorganized as an ASME Committeeoperating under procedures accredited by ANSI. The 1986 Edition of the standard removedmetric equivalents (not functionally applicable in th
21、e plumbing industry), updated the referencedstandards, and incorporated editorial and format revisions. The 1994 Edition removed inspectiontolerance requirements, established minimum laying lengths, added soil pipe adapters, andincorporated editorial revisions. Following approval by the Standards Co
22、mmittee and ASME,approval as an American National Standard was given by ANSI on October 10, 1994, with thedesignator ASME B16.29-1994.The 2001 Edition of this Standard was revised to include Nonmandatory Appendix B, QualitySystemProgram.Editorialrevisionsweremadeforthepurposeofclarification.Followin
23、gapprovalby the B16 Main Committee and ASME Supervisory Board, this Standard was approved as anAmerican National Standard by ANSI on October 11, 2001.In the 2007 Edition, metric units were used as a primary reference unit while maintainingU.S. Customary units in either parenthetical or separate form
24、s. In addition, several editorials andrevisions have been made for clarity.In this 2012 Edition, references to ASME standards were revised to no longer list specific editionyears; the latest edition of ASME publications applies unless stated otherwise. Following approvalby the B16 Standards Committe
25、e and the ASME Supervisory Board, and after public review, thisStandard was approved as an American National Standard by ANSI on August 23, 2012.Requests for interpretations or suggestions for revisions should be sent to the Secretary,B16 Committee, The American Society of Mechanical Engineers, Thre

31、SME B16.29-2012 includes the following changes identified by a margin note, (12). In addition,in the main text, the “General” section was moved to section 2, and subsequent sections andtheir paragraphs were renumbered accordingly.

33、12WROUGHT COPPER AND WROUGHT COPPER ALLOYSOLDER-JOINT DRAINAGE FITTINGS DWV1 SCOPEThis Standard for wrought copper and wrought cop-per alloy solder-joint drainage fittings, designed for usewith copper drainage tube conforming to ASTM B306,covers the following:(a) description(b) pitch (slope)(c) abbr
34、eviations for end connections(d) sizes and method of designating openings forreducing fittings(e) marking(f) material(g) dimensions and tolerances2 GENERAL2.1 ConventionFor determining conformance with this Standard, theconvention for fixing significant digits where limits(maximum and minimum values
35、) are specified shall beas defined in ASTM E29. This requires that an observedor calculated value be rounded off to the nearest unitin the last right-hand digit used for expressing the limit.Decimal values and tolerances do not imply a particularmethod of measurement.2.2 Relevant UnitsThis Standard
36、states values in both SI (metric) andU.S. Customary units. These systems of units are to beregarded separately as standard. Within the text, theU.S. Customary units are shown in parentheses or inseparate tables that appear in Mandatory Appendix I.The values stated in each system are not exact equiva
37、-lents; therefore, it is required that each system of unitsbe used independently of the other. Combining valuesfrom the two systems constitutes nonconformance withthe Standard.2.3 ReferencesCodes, standards, and specifications, containing pro-visions to the extent referenced herein, constituterequir
38、ements of this Standard. These reference docu-ments are listed in Mandatory Appendix II.12.4 Quality SystemsGuidelines relating to the product manufacturersquality system programs are described inNonmandatory Appendix A.3 DESCRIPTIONThese fittings are designed for drainage and vent sys-tems only, us

Thedimensions specified herein shall govern in all cases.4 PITCH (SLOPE)All nominal 90-deg fittin

The size designations for the fi
43、tting endconfigurations defined in Table 1 (Table I-1) correspondto drainage tube sizes defined in ASTM B306.6.1.2 Pipe. The size designation of threaded fittingend configurations defined in Table 2 (Table I-2) corres-ponds to thread sizes defined in ASME B1.20.1.6.2 IdentificationFittings shall be
44、identified by the nominal size of theopenings in the sequence illustrated in Fig. 1.7 MARKINGEach fitting shall be marked permanently and legiblywith the manufacturers name or trademark and withDWV (to indicate drain-waste-vent).8 MATERIALFittings shall be made of wrought copper or wroughtcopper all
45、oy material having not less than 84% of coppercontent.9 LAYING LENGTHSDue to widely varying manufacturing processes, lay-ing length dimensions of fittings are not standardized.Consult the manufacturer for these dimensions. Sug-gested dimensions, including laying lengths, for variousfitting configura
46、tions are shown in Tables 3 through 13(Tables I-3 through I-13).10 OVALITYMaximum ovality shall not exceed 1% of the maxi-mum diameter shown in Table 1 (Table I-1). The averageof the maximum and minimum diameters must bewithin the dimensions shown in the table.11 THREADED ENDS11.1 GeneralFitting thr
47、eads shall be right hand, conforming toASME B1.20.1. They shall be American NationalStandard taper pipe threads (NPT), except for slip jointends, which shall have American National Standardfree-fitting straight mechanical pipe threads (NPSM).11.2 ChamferAll internal threads shall be countersunk a di
48、stancenot less than one-half the pitch of the thread at an angleof approximately 45 deg with the axis of the thread. Allexternal threads shall be chamfered at an angle of 30 deg2to 45 deg from the axis. Countersinking and chamferingshall be concentric with the threads. The length ofthreads shall be
49、measured to include the countersink orchamfer.11.3 Threading Tolerances11.3.1 Internal Threads. Variations in NPT internalthreading shall be limited to one turn large or one turnsmall from the gaging notch when using working gages.The reference point for gaging is the starting end of thefitting, provided the chamfer does not exceed the majordiameter of the internal thread. When a chamfer on theinternal thread exceeds this limit, the reference pointbecomes the last thread scratch on the chamfer cone.11.3.2 External Threads.
