Designation:A1023/A1023M15Standard Specification forStranded Carbon Steel Wire Ropes for General Purposes1This standard is issued under the fixed designation A1023/A1023M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers the general requirements forthe more common types of stranded steel wire ropes.Includedin this specification are wire ropes in various grades andconstructions from14in.6 mm to 238in.60 mm manufac-tured from uncoated or metallic coated wire.Also included arecord products from132in.0.8 mm to38in.10 mmmanufactured from metallic coated wire.For specificapplications,additional or alternative requirements may apply.1.2 The values stated in either inch-pounds or SI units are tobe regarded separately as standard.Within the text,the SI unitsare shown in brackets.The values stated in each system are notexact equivalents;therefore,each system shall be used inde-pendently of the other.Combining values from the two systemsmay result in nonconformance with the specification.2.Referenced Documents2.1 ASTM Standards:2A931 Test Method for Tension Testing of Wire Ropes andStrandA1007 Specification for Carbon Steel Wire for Wire Rope2.2 ISO Standards:3ISO 2232 Round Drawn Wire for General-Purpose Non-alloy Steel Wire RopesISO 3108 Steel Wire Ropes for General PurposesDetermination of Actual Breaking3.TerminologyDescription of Terms Specific to this Specification3.1 inserts,nfiber or solid polymer so positioned as toseparate adjacent strands or wires in the same or overlyinglayers or to fill interstices of the rope.3.2 Lubrication:3.2.1 impregnating compound,nmaterial used in themanufacture of natural fiber cores,covers,or inserts for thepurpose of providing protection against rotting and decay ofthe fiber material.3.2.2 preservation compound,nmaterial,usually contain-ing some form of blocking agent,applied during,after,or bothduring and after manufacture of the rope to fiber inserts,fillers,and coverings for the purpose of providing protection againstcorrosion.3.2.3 rope lubricant,ngeneral term used to signify mate-rial applied during the manufacture of a strand,core,or ropefor the purpose of reducing internal friction,providing protec-tion against corrosion,or both.3.3 rope cores,ncentral element,usually of fiber or steel(but may be a combination of both),of a round rope aroundwhich are laid helically the strands of a stranded rope or theunit ropes of a cable-laid rope(Fig.1).3.3.1 fiber core(FC),nan element made from eithernatural or synthetic fibers.3.3.2 solid polymer core,na single element of solidpolymer material that is either cylindrical or shaped(grooved).It may also include an element or elements of wire or fiber.3.3.3 steel core,na stranded rope(IWRC),or a roundstrand(WSC)construction.The round strand or the strandedrope core or its outer strands,or both,may also be covered orfilled with either fiber or solid polymer.Steel cores arenormally made as a separate independent element,the excep-tion being rope with a stranded rope core closed parallel withthe outer strands.3.4 strand,nan element of rope normally consisting of anassembly of wires of appropriate shape and dimensions laidhelically in one or more layers around a center.The center mayconsist of one round or shaped wire,of several round wiresforming a built-up center,or of fiber or some other material.Ifmultiple wires are used in a strand center,they may be countedas one wire.3.4.1 Cross-Section Shape:3.4.1.1 compacted strand,na strand that has been sub-jected to a compacting process such as drawing,rolling,orswaging(Fig.2).1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloysand is the direct responsibility of SubcommitteeA01.03 on Steel Rod and Wire.Current edition approved May 1,2015.Published June 2015.Originallyapproved in 2002.Last previous edition approved in 2009 as A1023/A1023M 092.DOI:10.1520/A1023_A1023M-15.2For 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 International Organization for Standardization(ISO),1 rue deVaremb,Case postale 56,CH-1211,Geneva 20,Switzerland,http:/www.iso.ch.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.4.1.2 round strand,nstrand having a perpendicularcross-section that is approximately the shape of a circle(Fig.3).3.4.1.3 triangular strand,nstrand having a perpendicularcross-section that is approximately the shape of a triangle(formerly referred to as flattened strand)(Fig.4).(a)Style BSolid center wire.(b)Style G
