Development work culminated in the publicat
15、ion of ASA A40.3-1941. The standardbenefited from work done by A. R. Maupin of the National Bureau of Standards, both beforeand during its development, on the strength of solder joints.In 1949, work on these fittings was transferred to Sectional Committee B16, which establishedSubcommittee 9 (now Su
16、bcommittee J) with a scope broader than plumbing applications. Thefirst standard developed was approved as ASA B16.18-1950, Cast-Brass Solder Joint Fittings. Itwas then decided to revise A40.3 as a B16 standard covering only wrought solder-joint fittings.This effort was facilitated by a 1950 draft p
17、repared by joint effort of the Copper and Brass ResearchAssociation and the Manufacturers Standardization Society of the Valve and Fittings Industry(MSS). The draft, after review and approval by Subcommittee 9 and the Sectional Committee,was approved as B16.22-1951.Revisions were published as ASA B1
18、6.22-1963 and, after reorganization of ASA as the AmericanNational Standards Institute (ANSI), as ANSI B16.22-1973. In these editions, updated practices,new materials, and new types of fittings were incorporated into the standard, as well as editorialimprovements and updating of referenced specifica
19、tions and standards.In 1979, Subcommittee I (formerly 9, now J) added metric dimensional equivalents and madeother minor improvements. This revision was approved by ANSI, after approval by the Committeeand secretariat organizations, as ANSI B16.22-1980.In 1982, American National Standards Committee
20、B16 was reorganized as an ASME Committeeoperating 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 forthreaded ends, revised solder-joint lengths f
21、or18-in. size external and internal ends, and revisedminimum wall-thickness values based on a comprehensive bursting-test study. Following approvalby the Standards Committee and ASME, approval as an American National Standard was givenby ANSI on July 24, 1995, with the new designation ASME B16.22-19
22、95.In 1998, editorial revisions, which included the addition of a new section on quality systemsand a change in the designation of ASTM B32 alloys, were issued as an addendum. This addendumto the 1995 Edition of ASME B16.22, after approval by the ASME B16 Committee and ASME,was approved as ASME B16.
23、22a-1998.In the 2001 Edition, Subcommittee J converted the physical requirements to SI (metric) unitsof measure, added requirements for tube stops, clarified ovulate and alignment requirements,and made numerous editorial revisions. Alloy E and Alloy HB were incorporated into the tablelisting pressur
24、etemperature ratings for the soldering and brazing materials, plus values for the955 tinantimony solder were revised. These revisions to pressuretemperature ratings reflectedthe data from a National Institute of Standards and Technology (NIST) solder-joint testing study,initiated in 1993 to develop
25、stress rupture and strength data on copper tube sleeve joints usingvarious solders. Following approval by the ASME B16 Standards Committee, approval as anAmerican National Standard was given by ANSI on October 11, 2001, with the new designationASME B16.22-2001.In the 2012 Edition, the phrase “pressu
26、retemperature ratings” replaced “working pressure”throughout the text. Following approval by the ASME B16 Standards Committee, approval asan American National Standard was given by ANSI on October 22, 2012, with the new designationASME B16.22-2012.In this 2013 Edition, provisions have been included
27、to recognize low lead alloys to complywith the U.S. Safe Drinking Water Act which will be effective January, 2014. Following approvalby the ASME B16 Standards Committee, approval as an American National Standard was givenby ANSI on July 29, 2013, with the new designation ASME B16.22-2013.ivRequests

35、nd general plumbingsystems), ASTM B280 (air conditioning and refrigerationservice), and ASTM B819 (medical gas systems), as wellas fittings intended to be assembled with solderingmaterials conforming to ASTM B32, brazing materialsconforming to AWS A5.8, or with tapered pipe threadconforming to ASME
36、B1.20.1.This Standard is allied with ASME B16.18, which cov-ers cast copper alloy pressure fittings. It providesrequirements for fitting ends suitable for soldering. ThisStandard covers the following:(a) pressuretemperature ratings(b) abbreviations for end connections(c) size and method of designati
37、ng openings offittings(d) marking(e) material(f) dimensions 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, theU.S. Customary units are shown i
38、n parentheses or inseparate tables that appear in Mandatory Appendix II.The values stated in each system are not exact equiva-lents; therefore, it is required that each system of unitsbe used independently of the other. Combining valuesfrom the two systems constitutes nonconformance withthe Standard
39、.2.2 ReferencesStandards and specifications adopted by reference inthis Standard are shown in Mandatory Appendix III. Itis not considered practical to identify the specific editionof each standard and specification in the individual ref-erences. Instead, the specific edition reference is identi-fied
40、 in Mandatory Appendix III.12.3 Quality SystemsRequirements relating to the product manufacturersquality system program are described in NonmandatoryAppendix B.3 PRESSURETEMPERATURE RATINGS3.1 Rating of Fittings and JointsThe internal pressuretemperature rating for a solder-joint system is dependent
41、 upon not only fitting and tubestrength, but also composition of the solder used for thejoint and selection of valves and appurtenances.3.1.1 Solder Joints. Pressuretemperature ratingsfor solder joints to the dimensions of Table 1 (Table II-1),made with typical commercial solders, are given inTable
42、I-1 (Table II-4).The internal pressuretemperature rating of the sys-tem with solder joints shall be the lowest of the valuesshown in Table 2 (Table II-2) and Table I-1 (Table II-4)and those of the tube, valves, and appurtenances.3.1.2 Braze Joints. Pressuretemperature ratings forbraze joints to the
43、dimensions of Table 1 (Table II-1),made with typical commercial brazing materials, shallbe considered equal to the values given in Table 2(Table II-2).The internal pressuretemperature rating of the sys-tem with braze joints shall be the lowest of the valuesshown in Table 2 (Table II-2) and those of
44、the tube,values, and appurtenances.3.2 Bursting StrengthFittings manufactured to the Standard shall have anambient temperature bursting strength of at least fourtimes the 38C (100F) internal pressure rating as shownin Table 2 (Table II-2).4 TERMINOLOGY4.1 SizeThe size of the fittings shown in Table
45、1 (Table II-1)corresponds to standard water tube size as shown inASTM B88. The size of the threaded ends correspondsto nominal pipe size as shown in ASME B1.20.1.Fittings are designated by the size of the openings inthe sequence illustrated in Fig. 1.ASME B16.22-2013Table 1 Dimensions of Solder-Join
