D
14、evelopment work culminated in publication of ASA A40.3-1941. The standard benefited from work done by Mr. A. R. Maupin of the National Bureauof Standards, both before and during its development, on the strength of solder joints.In 1949, work on these fittings was transferred to Sectional Committee B
15、16, whichestablished Subcommittee 9 (now Subcommittee J) with a scope broader than plumbingapplications. The first standard developed was approved as ASA B16.18-1950, Cast-BrassSolder Joint Fittings. It was then decided to revise A40.3 as a B16 standard covering onlywrought solder-joint fittings. Th
16、is effort was facilitated by a 1950 draft prepared by jointeffort of the Copper and Brass Research Association and the Manufacturers StandardizationSociety of the Valve and Fittings Industry (MSS). The draft, after review and approval bySubcommittee 9 and the Sectional Committee, was approved as B16
17、.22-1951.Revisions were published as ASA B16.22-1963 and, after reorganization of ASA as theAmerican National Standards Institute (ANSI), as ANSI B16.22-1973. In these editions,updated practices, new materials, and new types of fittings were incorporated into thestandard, as well as editorial improv
18、ements and updating of referenced specifications andstandards.In 1979, Subcommittee I (formerly 9, now J) added metric dimensional equivalents andmade other minor improvements. This revision was approved by ANSI, after approval bythe Committee and secretariat organizations, as ANSI B16.22-1980.In 19
19、82, American National Standards Committee B16 was reorganized as an ASMECommittee operating under procedures accredited by ANSI.In 1989, Subcommittee J removed metric equivalents and updated referenced standards.In 1995, Subcommittee J defined bursting strength, defined standard gaging method forthr
20、eaded ends, revised solder-joint lengths for18in. size external and internal ends, andrevised minimum wall-thickness values based on a comprehensive bursting-test study.Following approval by the Standards Committee and ASME, approval as an AmericanNational Standard was given by ANSI on July 24, 1995
21、, with the new designation ASMEB16.22-1995.In 1998, editorial revisions, which included the addition of a new section on qualitysystems and a change in the designation of ASTM B 32 alloys, were issued as an addendum.This addendum to the 1995 edition of ASME B16.22, after approval by the ASME B16Comm
22、ittee and ASME, was approved as ASME B16.22a-1998.In this 2001 edition, Subcommittee J converted the physical requirements to SI (metric)units of measure, added requirements for tube stops, clarified ovulate and alignmentrequirements, and made numerous editorial revisions. Alloy E and Alloy HB were
23、incorporatedinto the table listing pressuretemperature ratings for the soldering and brazing materials,plus values for the 955 tinantimony solder were revised. These revisions to pressuretemperature ratings reflect the data from a National Institute of Standards and Technology(NIST) solder-joint tes
24、ting study, initiated in 1993 to develop stress rupture and strengthdata on copper tube sleeve joints using various solders.

29、peci-fied shall be rounding off as defined in ASTM E 29.This requires that an observed or calculated value shallbe rounded off to the nearest unit in the last right-hand digit used for expressing the limit.1.3 Units of MeasureThe values stated in either SI (metric) or U.S.customary (in.-lb) units of
30、 measure shall be regardedseparately as standard. Within the main text, SI unitsare given. For convenience, the customary units areshown in Mandatory Appendix II. The values stated1in each system are not exact equivalents; therefore,each system shall be used independently of the other.NOTE: Combinin
31、g values from the two systems may result innonconformance with the Standard.1.4 ReferencesStandards and specifications adopted by reference inthis Standard are shown in Mandatory Appendix III.It is not considered practical to identify the specificedition of each standard and specification in the ind

33、king pressuretemperature rating fora solder-joint system is dependent upon not only fittingand tube strength, but also composition of the solderused for the joint and selection of valves and appurte-nances.Pressuretemperature ratings for solder joints to thedimensions of Table 3 (Table II3), made wi
34、th typicalcommercial solders, are given in Table I1 (Table II4).The internal working-pressure rating of the systemshall be the lowest of the values shown in Table 1(Table II1) and Table I1 (Table II4), and those of thetube, valves, or appurtenances.2.2 Bursting StrengthFittings manufactured to the S
