Designation:D578/D578M05(Reapproved 2011)1Standard Specification forGlass Fiber Strands1This standard is issued under the fixed designation D578/D578M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript 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.1NOTEEditorial changes were made throughout in August 2011.1.Scope1.1 This specification covers the requirements for continu-ous fiber and staple fiber glass strands,including single,pliedand multiple wound.It also covers textured glass fiber yarns.This specification is intended to assist ultimate users bydesignating the general nomenclature for the strand productsthat age generally manufactured in the glass fiber industry.1.2 Glass fibers are produced having various compositions.General applications are identified by means of a letterdesignation.The letter designation represents a family ofglasses that have provided acceptable performance to theend-user in the intended application.For example,the compo-sition limits stated for E-Glass in this specification representingthe glass fiber family for general and most electrical applica-tions is designated by the letter E.Military specifications,suchas,MIL-R-60346,recognize the composition limits describedin this specification as meeting the respective requirements forE-Glass strands used in reinforced plastic structure applica-tions.1.3 Glass fiber strands have a variety of general uses underspecific conditions,such as high physical or chemical stress,high moisture,high temperature,or electrical environments.Property requirements under specific conditions are agreedupon between the purchaser and the supplier.Electrical prop-erty requirements vary with specific end-use applications.Forprinted circuit board applications,other requirements may beneeded such as the use of Institute for Interconnecting andPackaging Electronic Circuits(IPC)Specification EG 4412 Afor finished fabric woven from E-Glass for printed circuitboards,or Specification MIL-P-13949 for printed wiringboards applicable to glass fabric base.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This specification is one of a series to provide asubstitute for Military Specifications:MIL-Y-1140 Yarn,Cord,Sleeving,Cloth and Tape-Glass;and MIL-C-9084 Cloth,GlassFinished for Resin Laminates.1.6 AdditionalASTM specifications in this series have beendrafted and appear in current editions of the Annual Book ofASTM Standards.These include finished glass fabrics,unfin-ished glass fabrics,glass tapes,glass sleevings,glass cords,glass sewing threads,and finished laminates made from fin-ished glass fabrics.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD1423 Test Method for Twist in Yarns by Direct-CountingD1907 Test Method for Linear Density of Yarn(Yarn Num-ber)by the Skein MethodD2256/D2256M Test Method for Tensile Properties of Yarnsby the Single-Strand MethodD2258 Practice for Sampling Yarn for TestingD2904 Practice for Interlaboratory Testing of a Textile TestMethod that Produces Normally Distributed Data(With-drawn 2008)3D2906 Practice for Statements on Precision and Bias forTextiles(Withdrawn 2008)31This specification is under the jurisdiction of ASTM Committee D13 onTextiles and is the direct responsibility of Subcommittee D13.18 on Glass Fiber andits Products.Current edition approved July 1,2011.Published September 2011.Originallyapproved in 1940.Last previous edition approved in 2005 as D578 05.DOI:10.1520/D0578-05R11E01.2For 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 D4963 Test Method for Ignition Loss of Glass Strands andFabricsD7018 Terminology Relating to Glass Fiber and Its Products2.2 ASTM Adjunct:TEX-PAC42.3 ANSI Standard:ANSI/ASQC Z1.4 Sampling Procedures for Inspection byAttributes52.4 Military Standards and Specifications:MIL-P-13949 Spe
