Designation:B82816Standard Practice forMaking Capillary Joints by Soldering of Copper and CopperAlloy Tube and Fittings1This standard is issued under the fixed designation B828;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice describes a procedure for making capillaryjoints by soldering of copper and copper alloy tube and fittings.1.2 This procedure is applicable to pressurized systems suchasplumbing,heating,airconditioning,refrigeration,mechanical,fire sprinkler,and other similar systems.ASMEB31.5 and B31.9 reference the techniques used for satisfactoryjoint preparation.It is also used in the assembly of nonpres-surized systems such as drainage,waste,and vent.1.3 It is not applicable to the assembly of electrical orelectronic systems.1.4 Tube and fittings are manufactured within certain toler-ances to provide for the small variations in dimensionsassociated with manufacturing practice.Applicable specifica-tions are listed in Appendix X1.1.5 A variety of solders are available that will producesound,leak-tight joints.Choice of solder will depend upon thetype of application and on local codes.For potable watersystems,only lead-free solders shall be used,some of whichare described in Specification B32.1.6 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For hazardstatements,see the warning statements in 6.4.1,6.6.1,and6.6.3.2.Referenced Documents2.1 ASTM Standards:2B32 Specification for Solder MetalB68/B68M Specification for Seamless Copper Tube,BrightAnnealedB75/B75M Specification for Seamless Copper TubeB88 Specification for Seamless Copper Water TubeB88M Specification for Seamless Copper Water Tube(Met-ric)B280 Specification for Seamless Copper Tube for Air Con-ditioning and Refrigeration Field ServiceB306 Specification for Copper Drainage Tube(DWV)B447 Specification for Welded Copper TubeB640 Specification for Welded Copper Tube for Air Condi-tioning and Refrigeration ServiceB641 Specification for Seamless and Welded Copper Distri-bution Tube(Type D)(Withdrawn 1996)3B716 Specification for Welded Copper Water Tube(With-drawn 1994)3B716M Specification for Welded Copper Water Tube(Met-ric)(Withdrawn 1994)3B813 Specification for Liquid and Paste Fluxes for Solder-ing of Copper and Copper Alloy TubeB846 Terminology for Copper and Copper Alloys2.2 ASME Documents:4ASME B31.5 Refrigeration PipingASME B31.9 Building Services PipingASME B16.18 Cast Copper Alloy Solder Joint PressureFittingsASME B16.22 Wrought Copper and Copper Alloy SolderJoint Pressure FittingsASME B16.23 Cast Copper Alloy Solder Joint DrainageFittingsDWV1This practice is under the jurisdiction ofASTM Committee B05 on Copper andCopper Alloys and is the direct responsibility of Subcommittee B05.04 on Pipe andTube.Current edition approved June 1,2016.Published June 2016.Originallyapproved in 1992.Last previous edition approved in 2010 as B828 02(2010).DOI:10.1520/B0828-16.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 ASME B16.29 Wrought Copper and Copper Alloy SolderJoint Drainage FittingsDWV2.3 ANSI Document:5ANSI Z49.1 Safety in Welding and Cutting3.Terminology3.1 For definitions of terms related to copper and copperalloys,refer to Terminology B846.3.2 Definitions of Terms Specific to This Standard:3.2.1 solderinga group of joining processes that producecoalescence of materials by heating them to the solderingtemperature and by using a filler metal(solder)having aliquidus not exceeding 840F(450C)and below the solidus ofthe base metals.63.2.1.1 DiscussionIn actual practice,most soldering isdone at temperatures from about 350 to 660F(177 to 349C).4.Summary of Practice4.1 To consistently make satisfactory joints,the followingsequence of joint preparation and operatio
