Designation:B32401(Reapproved 2016)Standard Specification forAluminum Rectangular and Square Wire for ElectricalPurposes1This standard is issued under the fixed designation B324;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-O,annealed,1350-H12 or-H22(14hard),1350-H14 or-H24(12hard),1350-H16 or-H26(34hard),and 1350-H19(extra hard)wire,rectangular or square in shape with rounded corners for use aselectrical conductors in insulated magnet wire.1.2 The values stated in inch-pound or SI units are to beregarded separately as standard.Each system shall be usedindependently of the other.Combining the values from the twosystems may result in non-conformance with the specification.For conductor sizes designated by AWG or kcmil sizes,therequirements in SI units are numerically converted from thecorresponding requirements in inch-pound units.For conductorsizes designated byAWG or kcmil,the requirements in SI unitshave been numerically converted from corresponding valuesstated or derived in inch-pound units.for conductor sizesdesignated by SI units only,the requirements are stated orderived in SI units.1.2.1 For density,resistivity and temperature,the valuesstated in SI units are to be regarded as standard.NOTE1The aluminum and temper designations conform to ANSIH35.1.Aluminum 1350 corresponds to Unified Numbering SystemA91350 in accordance with Practice E527.2.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:2B193 Test Method for Resistivity of Electrical ConductorMaterialsB233 Specification for Aluminum 1350 Drawing Stock forElectrical PurposesB279 Test Method for Stiffness of Bare Soft Square andRectangular Copper andAluminum Wire for Magnet WireFabricationB557 Test Methods for Tension Testing Wrought and CastAluminum-and Magnesium-Alloy ProductsB830 Specification for Uniform Test Methods and Fre-quencyE29 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 ANSI Standard:H35.1/H35.1(M)Standard for Alloy and Temper Designa-tion Systems for Aluminum32.4 American National Standards:NBS Handbook 100 Copper Wire Tables4NBS Handbook 109 Aluminum Wire Tables43.Description of Terms Specific to This Standard3.1 lotan inspection lot shall consist of an identifiablequantity of wire subjected to inspection at one time.Each lotshall consist of units of wire of the same size and temper,manufactured under essentially the same conditions at essen-tially the same time.The amount in any case shall not exceed30 000 lb(14 000 kg).3.2 samplea quantity of production units(coils,reels,spools)selected at random from the lot for the purpose ofdetermining conformance of the lot to the requirements of thisspecification.3.3 sample sizethe number of production units selected.3.4 specimena length of wire removed for test purposesfrom any individual production unit of the sample.4.Ordering Information4.1 Orders for material under this specification shall includethe following information:1This specification is under the jurisdiction of ASTM Committee B01 onElectrical Conductors and is the direct responsibility of Subcommittee B01.07 onConductors of Light Metals.Current edition approved Oct.1,2016.Published October 2016.Originallyapproved in 1984.Last previous edition approved in 2012 as B324 01(2012).DOI:10.1520/B0324-01R16.2For 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 Institute of Standards and Technology(NIST),100Bureau Dr.,Stop 1070,Gaithersburg,MD 20899-1070,http:/www.nist.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.1.1 Quantity and temper of each size and shape(seeSection 5),4.1.2 Wire size;thickness and width in inches or in milli-metres(see Section 7),4.1.3 Mandrel diameter for the edgewise bend test,4.1.4 Place of inspection if other than at place of manufac-ture(see 12.2),4.1.5 Whether inspection or witness of inspection and testsby purchasers representative is required prior to shipment(see12.3),4.1.6 Packaging and marking(see Section 13),and4.1.7 Special package marking,if required(see 13.4).5.Materials and Manufacture5.1 Material:5.1.1 The aluminum wire shall be made from rod inaccordance w
