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) culminatedina standardonwrought fittings,ultimatelyapproved asB16.22-1951.Concurrently,recognizingtheneedfordrainagefittingstandards,anMSStaskgroupdevelopedthe standard later approved as ASA B16.23-1953, Cast Bronze Solder-Joint Drainage Fittings, anda standard
18、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 as ASAB16.29-1966.A revision was published after reorganization of ASA as the American National StandardsInstitute (ANSI) as ANSI B16.29-1973.
19、 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 approval by the Committ
20、ee and secretariat organizations, as ANSIB16.29-1980.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 the plumbing industry)
21、, 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 Committee and ASME,app
22、roval 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.Followingapprovalby the B16

36、se of determining conformance withthisStandard,theconventionforfixingsignificantdigitswherelimits(maximumandminimumvalues)arespeci-fied shall be rounding off as defined in ASTM E 29. Thisrequires that an observed or calculated value shall berounded off to the nearest unit in the last right-handdigit
37、 used for expressing the limit. Decimal values andtolerances do not imply a particular method of mea-surement.1.3 Relevant UnitsThis Standard states values in both metric and U.S.Customary units. These systems of units are to beregarded separately as standard. Within the text, theU.S. Customary unit
38、s are shown in parentheses or inseparate tables. (Tables showing dimensions in equiva-lent U.S. Customary units are found in MandatoryAppendix I.) The values stated in each system are notexact equivalents; therefore, it is required that each sys-temofunitsbeusedindependentlyoftheother.Combin-ing val
