Designation:D580/D580M15Standard Specification forGreige Woven Glass Tapes and Webbings1This standard is issued under the fixed designation D580/D580M;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.1.Scope1.1 This specification primarily covers greige tapes andwebbings woven from“E”electrical classification glass fiberyarns.This specification can also be applied to tapes andwebbings made of other glass fiber grades upon agreementbetween the purchaser and the supplier.1.2 This specification is intended to assist ultimate users bydesignating the types of these products that are typical in theindustry.This specification permits the application of organicmaterials to the glass fiber yarn during manufacture that helpsfacilitateweaving.Whenusedaspermittedinthisspecification,such materials will not interfere with the in-tended end use requirements.1.3 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 nonconformancewith the standard.1.4 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 TextilesD578 Specification for Glass Fiber StrandsD579 Specification for Greige Woven Glass FabricsD1059 Test Method for Yarn Number Based on Short-Length Specimens(Withdrawn 2010)3D1423 Test Method for Twist in Yarns by Direct-CountingD1776 Practice for Conditioning and Testing TextilesD1777 Test Method for Thickness of Textile MaterialsD3773 Test Methods for Length of Woven FabricD3774 Test Method for Width of Textile FabricD3775 Test Method for Warp(End)and Filling(Pick)Countof Woven FabricsD4963 Test Method for Ignition Loss of Glass Strands andFabricsD5035 Test Method for Breaking Force and Elongation ofTextile Fabrics(Strip Method)D7018 Terminology Relating to Glass Fiber and Its Products2.2 ANSI Standard:4ANSI/ASQC Z1.4 Sampling Procedures for Inspection byAttributes3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 For definitions of glass fiber and product terms used inthis specification refer to Terminology D7018.3.1.2 The following terms are relevant to this standard:continuous filament yarn,greige goods,tape,webbing.3.1.3 For definitions of other textile terminology used in thisspecification,refer to Terminology D123.4.Classification4.1 Greige glass fiber tapes and webbings are produced intwo types and are constructed with yarns designated as directedin Specification D578.The standard types are:4.1.1 Type AMedium texture.4.1.2 Type BOpen texture.4.2 The designation of a tape or webbing shall be by stylenumbers that are standard throughout the industry.4.3 Two segments of characters are used to describe tapesand webbings.4.3.1 The first segment of the description of tape or webbingdescribes the glass classification,the type fiber in the warp,andthe type fiber in the filling.4.3.1.1 The first letter in the first segment is one of thefollowing glass classification codes:“E”for electrical,“C”forchemical,“S”for high force.1This 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 Feb.1,2015.Published March 2015.Originallyapproved in 1940.Last previous edition approved in 2004 as D580/D580M 10.DOI:10.1520/D0580_D0580M-152For 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.4Available from American National Standards Institute,11 W.42nd St.,13thFloor,New York,NY 10036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.3.1.2 The second letter in the first segment specifies thefiber type in the warp direction:“C”describes continuousfilament fiber using either SI units or inch-pound units,staple(discontinuous)fiber is described by“D”in SI units or“S”ininch-pound units.4.3.1.3 The third letter in the first segment specifies the fibertype in the filling direction:“C”describes continuous filamentfiber using either SI units or inch-pound units,staple(discon-tinuous)fiber is described by“D”in SI units or“S”ininch-pou
