Designation:B90104(Reapproved 2015)Standard Specification forCompressed Round Stranded Aluminum Conductors UsingSingle Input Wire Construction1This standard is issued under the fixed designation B901;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.Scope1.1 This specification covers aluminum 1350-H19(extrahard),1350-H16 or-H26(34hard),1350-H14 or-H24(12hard),1350-H142 or-H242(12hard),and aluminum alloy8XXX series as listed in Specification B800 for tempers“O”and H1X or H2X,bare stranded conductors composed of oneor more roller shaped or die compressed layers of helicallylayed wires.The conductors are for general use for electricalpurposes(Explanatory Notes 1 and 2).NOTE1For the purposes of this specification,single input wire(SIW)construction is defined as follows:a stranded conductor design method-ology that varies the number of wires within a range of conductor sizes inorder to permit that range of conductor sizes to be constructed from asingle wire size.1.2 The SI values for resistivity are regarded as standard.For all other properties,the inch-pound units are regarded asstandard and the SI units may be approximate.NOTE2Prior to 1975,aluminum 1350 was designated as ECaluminum.NOTE3The aluminum and temper designations conform to ANSIH35.1.Aluminum 1350 corresponds to Unified Numbering SystemA91350 in accordance with Practice E527.Aluminum alloys in the 8000series correspond to Unified Numbering System A98XXX in accordancewith Practice E527.NOTE4This specification also permits conductors for use as coveredor insulated electrical conductors.NOTE5Sealed conductors,which are intended to prevent longitudinalwater propagation and are further covered/insulated,are also permittedwithin the guidelines of this specification.2.Referenced Documents2.1 The following documents of the issue in effect on thedate of material purchase form a part of this specification to theextent referenced herein.2.2 ASTM Standards:2B193 Test Method for Resistivity of Electrical ConductorMaterialsB230/B230M Specification for Aluminum 1350H19 Wirefor Electrical PurposesB263 Test Method for Determination of Cross-SectionalArea of Stranded ConductorsB354 Terminology Relating to Uninsulated Metallic Electri-cal ConductorsB609/B609M Specification for Aluminum 1350 RoundWire,Annealed and Intermediate Tempers,for ElectricalPurposesB800 Specification for 8000 Series Aluminum Alloy Wirefor Electrical PurposesAnnealed and Intermediate Tem-persB801 Specification for Concentric-Lay-Stranded Conductorsof 8000 Series Aluminum Alloy for Subsequent Coveringor InsulationE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE527 Practice for Numbering Metals and Alloys in theUnified Numbering System(UNS)2.3 Other Standards:ANSI H35.1 American National Standard Alloy and TemperDesignation System for Aluminum3NBS Handbook 100 Copper Wire Tables43.Classification3.1 The conductors described in this specification are in-tended for subsequent insulation or covering.The classificationof these conductors is SIW compressed.4.Ordering Information4.1 Orders for material under this specification shall includethe following information:1This specification is under the jurisdiction of ASTM Committee B01 ofElectrical Conductors and is the direct responsibility of Subcommittee B01.07 onConductors of Light Metals.Current edition approved Oct.1,2015.Published October 2015.Originallyapproved in 2000.Last previous edition approved in 2011 as B901 04(2011).DOI:10.1520/B0901-04R15.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from National Technical Information Service(NTIS),5301 ShawneeRd.,Alexandria,VA 22312,http:/www.ntis.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.1.1 Quantity,4.1.2 Conductor size:circular-mil area ofAWG(see Section8 and Table 1),4.1.3 Alloy designation,4.1.4 Class(see 3.1),4.1.5 Temper(see 5.1 and 5.3),4.1.6 Details of special-purpose lays,when required(see 7.2and 7.3),4.1.7 When tension tests are required on the completedconductor(see Section 15),4.1.8 Package size(see 19.1),4.1.9 Special package marking,if required(see Section 20),TABLE 1 Construction Requirements of Compressed Round SIW StrandedAluminum ConductorsConductor SizeHard Drawn CopperEquivalentMinimumNumberofNominalDiameter ofSIW Com-pressedConductorNominalDiameter ofSIW Com-pressedConductorMassDC Resistance at20CcmilsAWGmm2
