Designation:D4389/D4389M16Standard Specification forFinished Glass Fabrics Woven From Rovings1This standard is issued under the fixed designation D4389/D4389M;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 primarily covers glass fabrics wovenfrom“E”electrical continuous glass fiber rovings that areintended primarily as a reinforcing material in laminatedplastics for structural use.1.2 This specification specifies the terminology,definitions,general requirements,and physical requirements for wovenroving glass fiber fabrics.This specification permits the appli-cation of sizing materials to the glass fiber roving duringmanufacture that helps facilitate weaving.When used aspermitted in this specification,such materials are compatiblewith the resin matrix as specified in the contracting instrument.NOTE1Sizing materials on glass fiber yarns,in most cases,areremoved by various cleaning procedures as a first stage in preparing afinished fabric.When these yarn sizing materials are removed during acleaning procedure,they need not be compatible with the subsequent resinmatrix.1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded 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.NOTE2This specification is one of a series to provide a substitute forthe following Military Specifications:MIL-Y-1140H Yarn,Cord,Sleeving,Cloth,and Tape-GlassMIL-C-9084C Cloth,Glass Finished for Resin LaminatesMIL-C-19663C Cloth,Glass,Woven Roving for Plastic Laminates2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD578 Specification for Glass Fiber StrandsD1776 Practice for Conditioning and Testing TextilesD2408 Test Method for Finish Content of Woven GlassFabric,Cleaned and After-Finished With Amino-Silane-Type Finishes,for Plastic Laminates(Withdrawn 1988)3D2409 Test Method for Finish Content of Woven GlassFabric,Cleaned and After-Finished With Vinyl-SilaneType Finishes,for Plastic Laminates(Withdrawn 1988)3D2410 Test Method for Finish Content of Woven GlassFabric,Cleaned and After-Finished With ChromeComplexes,for Plastic Laminates(Withdrawn 1988)3D2660 Test Method for Finish Content of Woven GlassFabric,Cleaned and After-Finished with Acrylic-Silane-Type Finishes,for Plastic Laminates(Withdrawn 1988)3D3098 Test Method for Finish Content of Woven GlassFabrics,Cleaned and After-Finished with Epoxy-Functions Silane Type Finishes for Plastic Laminates(Withdrawn 1988)3D3773 Test Methods for Length of Woven FabricD3774 Test Method for Width of Textile FabricD3775 Test Method for Warp(End)and Filling(Pick)Countof Woven FabricsD3776 Test Methods for Mass Per Unit Area(Weight)ofFabricD4029 Specification for Finished Woven Glass FabricsD4963 Test Method for Ignition Loss of Glass Strands andFabricsD7018 Terminology Relating to Glass Fiber and Its Products2.2 ANSI Standard:ANSI/ASQC Z1.4 Sampling Procedures for Inspection byAttributes43.Terminology3.1 For definitions of glass fiber and product terms used inthis specification refer to Terminology D7018.3.1.1 The following terms are relevant to this standard:continuous filament yarn,roving.3.2 For definitions of other textile terms used in thisspecification,refer to Terminology D123.1This 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 Jan.1,2016.Published February 2016.Originallyapproved in 1984.Last previous edition approved in 2010 as D4389 04(20101).DOI:10.1520/D4389_D4389M-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.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 CLASSIFICATION4.Classification4.1 Designation of Woven Roving Fabric The basic des-ignations for glass woven roving fabric is by mass per unit areaand is given in grams per square metre(ounces per squareyard).Historically,anASTM type number has been used by theindustry.These numbers have been sequentially assigned asnew woven roving constructions as they were added to thisspecification.Numbers 1 through 10 are shown in Table 1 withthe relationship to mass per unit area and fabric
