Designation:B88M16Standard Specification forSeamless Copper Water Tube(Metric)1This standard is issued under the fixed designation B88M;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers seamless copper water tubesuitable for general plumbing,similar applications for theconveyance of fluids,and commonly used with solder,flared,or compression-type fittings.The type of copper water tubesuitable for any particular application is determined by theinternal or external fluid pressure,by the installation andservice conditions,and by local requirements.Means of joiningor bending are also factors that affect the selection of the typeof tube to be used.2NOTE1Annealed tube is suitable for use with flared or compressionfittings,and with solder-type fittings,provided rounding and sizing of thetube ends is performed where needed.NOTE2Drawn temper tube is suitable for use with solder-type fittings.Types A and B tube,in the drawn temper,are suitable for use with certaintypes and sizes of compression fittings.1.2 The tube shall be produced from the following coppers,and the manufacturer has the option to supply any one of them,unless otherwise specified:CopperUNS No.Previously UsedDesignationDescriptionC10200OFOxygen free withoutresidual deoxidantsC12000DLPPhosphorus deoxidized,low residual phosphorusC12200DHPPhosphorus deoxidized,high residual phosphorus1.3 The assembly of copper plumbing or fire sprinklersystems by soldering is described in Practice B828.1.4 Solders for joining copper potable water or fire sprinklersystems are covered by Specification B32.The requirementsfor acceptable fluxes for these systems are covered by Speci-fication B813.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.NOTE3This specification is the SI companion to Specification B88.1.6 The following safety hazards caveat pertains only to thetest methods portion,Section 15,of this specification:Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 The following documents of the issue in effect on dateof material purchase form a part of this specification to theextent referenced herein:2.2 ASTM Standards:3B32 Specification for Solder MetalB88 Specification for Seamless Copper Water TubeB153 Test Method for Expansion(Pin Test)of Copper andCopper-Alloy Pipe and TubingB577 Test Methods for Detection of Cuprous Oxide(Hydro-gen Embrittlement Susceptibility)in CopperB601 Classification for Temper Designations for Copper andCopper AlloysWrought and CastB813 Specification for Liquid and Paste Fluxes for Solder-ing of Copper and Copper Alloy TubeB828 Practice for Making Capillary Joints by Soldering ofCopper and Copper Alloy Tube and FittingsB846 Terminology for Copper and Copper AlloysB900 Practice for Packaging of Copper and Copper AlloyMill Products for U.S.Government AgenciesE8/E8M Test Methods for Tension Testing of Metallic Ma-terialsE18 Test Methods for Rockwell Hardness of Metallic Ma-terialsE29 Practice for Using Significant Digits in Test Data to1This specification is under the jurisdiction ofASTM Committee B05 on Copperand Copper Alloys and is the direct responsibility of Subcommittee B05.04 on Pipeand Tube.Current edition approved Oct.1,2016.Published November 2016.Originallyapproved in 1983.Last previous edition approved in 2013 as B88M 13.DOI:10.1520/B0088M-16.2The UNS system for copper and copper alloys(see Practice E527)is a simpleexpansion of the former standard designation system accomplished by the additionof a prefix“C”and a suffix“00.”The suffix is permitted to be used to accommodatecomposition variations of the base alloy.3For 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.*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 Determine Conformance with SpecificationsE53 Test Method for Determination of Copper in UnalloyedCopper by GravimetryE62 Test Methods for Chemical Analysis of Copper andCopperAlloys(Photometric Methods)(Withdrawn 2010)4E112 Test Methods for Determining Average Grain SizeE243 Practice for Electromagnetic(Eddy Current)Examina-tion of Copper and C
