Designation:B35416Standard Terminology Relating toUninsulated Metallic Electrical Conductors1This standard is issued under the fixed designation B354;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.INTRODUCTIONThese terminologies relate only to interpretations as applied to uninsulated metallic electricalconductors in specifications under the jurisdiction ofASTM Committee B01 on Electrical Conductors,and do not necessarily correspond to the definitions used in other fields.1.Scope1.1 This terminology standard defines abbreviations andterms specific to uninsulated electrical conductors.For termsrelating to superconductors,see Terminology B713.2.Referenced Documents2.1 ASTM Standards:2B193 Test Method for Resistivity of Electrical ConductorMaterialsB713 Terminology Relating to Superconductors(Withdrawn2001)3E8/E8M Test Methods for Tension Testing of Metallic Ma-terials3.AbbreviationsAAACall aluminum alloy conductorAACaluminum conductorAACSRaluminum alloy conductor,steel reinforcedACARaluminum conductor,aluminum alloy reinforcedACSRaluminum conductor,steel reinforcedACSSaluminum conductor steel supportedAMCaluminum matrix compositeAWold designation for what is now termed AW2AW2aluminum-clad steel core wire,normal strengthAW3aluminum-clad steel core wire,high strengthAZold designation(aluminized)CCAcopper-clad aluminumCCScopper-clad steelCOMPcompact constructionEHSextra high strengthGAold designation for what is now termed GA2GA2zinc coated(galvanized)steel wire,coating class AGA3zinc coated(galvanized)high strength steel wire,coating class AGA4zinc coated(galvanized)extra high strength steelwire,coating class AGA5zinc coated(galvanized)ultra high strength steelwire,coating class AGBobsolete designation,class B galvanizing is no longerofferedGCold designation for what is now termed GC2GC2zinc coated(galvanized)steel wire,coating class CHShigh strengthIACSinternational annealed copper standard,which is1/58 Ohm-mm2/m at 20C for 100%conductivityLSElow stress elongationMAold designation for what is now termed MA2MA2zinc-5%aluminum-mischmetal alloy coated steelwire,coating class AMA3zinc-5%aluminum-mischmetal alloy coated highstrength steel wire,coating class AMA4zinc-5%aluminum-mischmetal alloy coated extrahigh steel wire,coating class AMA5zinc-5%aluminum-mischmetal alloy coated ultrahigh steel wire,coating class AMBobsolete designation,class B galvanizing is no longerofferedMCold designation for what is now termed MC2MC2zinc-5%aluminum-mischmetal alloy coated steelwire,coating class CMSold designation for what is now termed MA3MMmischmetalNSnon-specularSDself dampening constructionSIWsingle input wire construction1This terminology is under the jurisdiction of ASTM Committee B01 onElectrical Conductors and is the direct responsibility of Subcommittee B01.01 onEditorial and Records.Current edition approved Sept.1,2016.Published September 2016.Originallyapproved in 1960.Last previous edition approved in 2012 as B354 12.DOI:10.1520/B0354-16.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 TPtwisted pairTWtrapezoidal shaped wireUHSultra high strengthUNSunified numbering systemZn-5Al-MMzinc-5%aluminum-mischmetal alloy coat-ing4.Terminology4.1 Definitions:aeolian vibrationresonant vibration of a conductor causedby the alternate shedding of wind-induced vortices fromopposite sides of the conductor.(Frequency is usually lessthan 200 Hz and amplitude rarely exceeds one conductordiameter.)anneal(annealing),na thermal treatment to change theproperties or grain structure of the product.When applied toa cold-worked product having a single phase:to producesoftening by recystallization or recrystallization and graingrowth with the accompanying changes in properties.Whenapplied to a product having two or more phases:to producesoftening by changes in the phase relationship that mayinclude recrystallization and grain growth.annealed wiresee soft wire.area densitymass per unit area.bare conductora conductor having no nonmetallic cover-ing.brazingthe joining of ends of two wires,rods,or groups ofwires with a nonferrous filler metal at temperatures above800F(427C).breaking strengththe maximum load that a conductorattains when tested in tension to rupture.bunch-stranded conductora conductor composed of wirestwisted together with a given length and direction of lay insuch manner that the respective wires at successive crossse
