    FOREWORD

    
    

    Standardization work on solder joint fittings began in 1936 in Subcommittee 11 of Sectional Committee A40, Minimum Requirements for Plumbing and Standardization of Plumbing Equipment, organized within the American Standards Association (ASA). It resulted in the publication, in January 1941, of ASA A40.3-1941. That standard covered only supply (pressure) fittings.

    In 1949, responsibility for solder joint fittings was transferred to newly formed Subcommittee 9 of Sectional Committee B16 on Standardization of Pipe Flanges and Fittings. The next revision of A40.3 appeared as ASA B16.18-1950, Cast-Brass Solder-Joint Fittings. During its development, however, the need for separate standards for wrought copper and wrought bronze supply fittings and for solder joint drainage fittings was recognized.

    Work on the wrought fitting standard was undertaken by a joint committee of the Copper and Brass Research Association and the Manufacturers’ Standardization Society of the Valve and Fittings Industry (MSS). That work, properly reviewed and approved, was published as ASA B16.22-1951.

    Concurrently, in June 1949, at the request of Subcommittee 9, a task group organized by MSS began work on a standard for cast brass solder joint drainage fittings. Representatives of all

    U.S. and Canadian manufacturers were invited to participate. The Report of the Coordinating Committee for a National Plumbing Code was taken into account; special research on wall thickness and depth of solder joint was conducted; and coordination with other standards was sought, to avoid inconsistency. After working through nine drafts to reach consensus, the group submitted an April 1952 draft to Subcommittee 9. After committee, sponsor, and ASA approval, the standard was approved as ASA B16.23-1953, Cast Brass Solder Joint Drainage Fittings, on January 30, 1953.

    Work soon began on a revision, to include additional sizes, reducing sizes, and additional types of fittings. A March 1955 draft was approved by the B16 Committee, sponsors, and ASA, and published as ASA B16.23-1955. Starting in 1958, responding to requests for further revision and expansion, the MSS task group developed a 1959 draft that was approved by Subcommittee 9, the B16 Committee, sponsors, and ASA, and was published as ASA B16.23-1960.

    In 1967 and 1968, a complete revision was undertaken, including engineering studies to verify that a user request for shorter soldering cups was justified. The resulting draft, after approval by Subcommittee 9, USA Standards Committee B16, sponsors, and the (then-called) USA Standards Institute, was published as USAS B16.23-1969. An addenda, dated 1973, lengthened the cups on the three smallest sizes to overcome assembly problems.

    The subcommittee, now Subcommittee I, began a new revision in 1974, resulting in the inclusion of the 1973 addenda, addition of metric equivalents, and change of “bronze” to “copper alloy.” The draft, finally approved by the (again renamed) American National Standards Institute (ANSI), was published as ANSI B16.23-1976.

    In 1982, a new edition updating dimensional tables and metric equivalents was developed. Following approval at all levels, the revision was published as ANSI B16.23-1984.

    Also in 1982, American National Standards Committee B16 became the ASME B16 Standards Committee, operating with the same scope, under ASME procedures accredited by ANSI. Subse- quently, Subcommittee I merged with Subcommittee J, which had a related scope.

    The 1992 edition removed metric units, establishing U.S. Customary units as the standard. Clarifications and updating changes were made to improve the text. The 2002 edition of B16.23 added SI units of measure in the main body of text and moved U.S. Customary units to Mandatory Appendix I. A Nonmandatory Appendix for Quality System Programs was added, plus editorial changes were made to improve text. Following approval by the Standards Committee and ASME, approval as an American National Standard was given on February 6, 2002, with the designation, ASME B16.23-2002.

    In the 2011 edition, references to ASME standards were revised to no longer list specific edition years. Following approval by the Standards Committee and the ASME Board on PTCS, the revision to the 2002 edition was approved as an American National Standard by ANSI on September 23, 2011 with the new designation, ASME B16.23-2011.

    In this 2016 edition, provisions have been made to update verbiage and readings. Following the approval by the ASME B16 Standards Committee, approval as an American National Standard was given by ANSI on October 21, 2016, with the new designation ASME B16.23-2016.

    CAST COPPER ALLOY SOLDER JOINT DRAINAGE FITTINGS: DWV

    
    

    1. 1 SCOPE

       This Standard establishes specifications for cast cop- per alloy solder joint drainage fittings, designed for use in drain, waste, and vent (DWV) systems. These fittings are designed for use with seamless copper tube conform- ing to ASTM B306, Copper Drainage Tube (DWV), as well as fittings intended to be assembled with soldering materials conforming to ASTM B32, or tapered pipe thread conforming to ASME B1.20.1.

       This Standard is allied with ASME B16.29, Wrought Copper and Wrought Copper Alloy Solder Joint Drainage Fittings — DWV.

       It provides requirements for fitting ends suitable for soldering. This Standard covers

       1. description

       2. pitch (slope)

       3. abbreviations for end connections

       4. sizes and methods for designing openings for reducing fittings

       5. marking

       6. material

       7. dimensions and tolerances

    
    

    1. GENERAL

       1. Relevant Units

          This Standard states values in both SI (Metric) and

          U.S. Customary units. These systems of units are to be regarded separately as standard. Within the text, the

          U.S. Customary units are shown in parentheses or in separate tables that appear in Mandatory Appendix I. The values stated in each system are not exact equiva- lents; therefore, it is required that each system of units be used independently of the other. Combining values from the two systems constitutes nonconformance with the Standard.

          
          

       2. References

          Standards and specifications adopted by reference in this Standard are shown in Mandatory Appendix II, which is part of this Standard. It is not considered practi- cal to identify the specific edition of each standard and specification in the individual references. Instead, the specific edition reference is identified in Mandatory Appendix II.

       3. Quality Systems

          Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.

          
          

    2. DESCRIPTION

       1. These fittings are designed for drainage and vent systems using the solder joint method of connection. The fitting cups (C), are provided with stops so that the ends of the tube, when assembled, meet the stops, thereby forming essentially smooth passageways.

       2. The sketches and designs of fittings are illustrative only. The dimensions specified herein shall govern in all cases.

       
       

    3. PITCH (SLOPE)

       All nominal 90-deg fittings shall be pitched to result in a slope of 21 mm/m (0.25 in./ft) (2.1%) of length of horizontal tube with reference to a horizontal plane (see Fig. 1).

       
       

    4. ABBREVIATIONS

       The following symbols are used to designate the type of fitting end:

       C p solder-joint fitting end made to receive copper tube diameter (female)

       F p internal ANSI Standard taper pipe thread (female) NPT

       FTG p solder-joint fitting end made to copper tube diameter (male)

       M p external ANSI Standard taper pipe thread (male) NPT

       NPSM p standard straight mechanical pipe thread SJ p end of fitting made to receive O.D. tube

       size

       
       

    5. SIZE

(a) The size of the fittings scheduled in Tables 1 through 56 and Tables I-1 through I-56 corresponds to the drainage tube size shown in ASTM B306. The size of the threaded ends (except slip joints) corresponds to the nominal pipe size.
