17、stem Program 48ivFOREWORDThis American National Standard for solder joint fittings was originally developed by a subcom-mittee of American Standards Association (ASA) Sectional Committee A40 on MinimumRequirements for Plumbing and Standardization of Plumbing Equipment, organized inAugust 1928, under
18、 the procedures of the ASA. Subcommittee No. 11 on Solder-Joint Fittingsfor Tubing was appointed in October 1936.At its first meeting, the subcommittee was informed of the investigation of solder joints beingcarried out by the National Bureau of Standards (now the National Institute of Standards and
19、Technology). It was decided that the committees scope should cover only solder fittings for usein plumbing. A subgroup was appointed to study the tolerances of commercial fittings, includingdepth of bore, laying lengths, and diameters of copper tube.A draft standard was sent to the subcommittee in F
20、ebruary 1939; a revision was distributedin August to selected organizations and individuals for review. A new subcommittee draft datedApril 1940 was approved by Sectional Committee A40, the sponsor, and following ASA approval,was published in January 1941 as ASA A40.3-1941.In 1949, the sponsors agre
21、ed to transfer responsibility for solder joint fittings to SectionalCommittee B16 of ASA, because the fittings were being used in many applications other thanplumbing. Subcommittee 9, Standardization of Solder Joint Fittings was established and chargedwith developing a revised standard. An April 194
22、9 draft was distributed for industry review,resulting in recommended changes. A new draft was approved by Sectional Committee B16,sponsor organizations, and ASA and published as ASA B16.18-1950.Work began in 1958 on a revision, including improvements in language. It was approved byB16, sponsor organ
23、izations, and ASA and published as ASA B16.18-1963. Starting in 1969, acomprehensive review resulted in revisions to clarify the text and to permit additional material.Final approval was granted by the American National Standards Institute (formerly ASA) onMarch 2, 1972, for publication as ANSI B16.
24、18-1972.The subcommittee, now Subcommittee I, began a new revision on 1974, resulting in the additionof supply and return tees, baseboard tees, and flush bushings, as well as metrication, and changeof “bronze” to “copper alloy.” The draft finally approved was published as ANSI B16.18-1978.In 1982, A
25、merican National Standards Committee B16 became the ASME B16 StandardsCommittee, operating with the same scope under ASME procedures accredited by ANSI. Subse-quently, Subcommittee I merged with Subcommittee J, which had a related scope. A generalreview was then started, resulting in a number of edi
26、torial changes and a few pictorial corrections.Table 2 (now Table 3) was updated to three place decimals from four, bringing the table morein line with practical gaging methods. Table B2 (now Table I-3) was correspondingly corrected.Following approval by Subcommittee J, the B16 Standards Committee,
27、and ASME, the AmericanNational Standards Institute granted approval on January 13, for publication as ANSI B16.18-1984.The standard was reaffirmed in 1994 with no change.The 2001 edition of B16.18 contained a defined bursting strength, defined standard gagingmethod of threaded ends, and other clarif
28、ications and updates to text. Following approval bythe Standards Committee and ASME, approval as an American National Standard was given onOctober 17, 2001 with the designation ASME B16.18-2001.In this edition, new copper alloys were added for potable water applications. Also, referencesto ASME stan
29、dards were revised to no longer list specific edition years; the latest edition ofASME publications applies unless stated otherwise. Materials manufactured to other editions ofthe referenced ASTM standards have been permitted to be used to manufacture fittings meetingthe requirements of this Standar
30、d as long as the fitting manufacturer verifies the material meetsvthe requirements of the referenced edition. Following approval by the B16 Standards Committeeand the ASME Board on PTCS, this revision to the 2001 edition was approved as an AmericanNational Standard by ANSI on January 13, 2012 with t
31、he new designation, ASME B16.18-2012.Requests for interpretations and suggestions for revision should be sent to the Secretary,B16 Committee, The American Society of Mechanical Engineers, Three Park Avenue, New York,NY 10016-5990.viASME B16 COMMITTEEStandardization of Valves, Flanges, Fittings, and

42、sions and tolerances(g) tests2 GENERAL2.1 Relevant UnitsThis Standard states values in both SI (Metric) andU.S. Customary units. These systems of units are to beregarded separately as standard. Within the text, the SIunits are shown in parentheses or in separate tables thatappear in Mandatory Append
43、ix I. The values stated ineach system are not exact equivalents; therefore, it isrequired that each system of units be used indepen-dently of the other. Combining values from the twosystems constitutes nonconformance with the Standard.2.2 ReferencesStandards and specifications adopted by reference i
44、nthis 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 andspecification in the individual references.
