Designation:D4029/D4029M10Standard Specification forFinished Woven Glass Fabrics1This standard is issued under the fixed designation D4029/D4029M;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 finished fabrics woven from“E”electrical glass fiber yarns that are intended as a reinforc-ing material in laminated plastics for structural use.Thisspecification can also be applied to fabrics made of other glasstypes as agreed upon between the purchaser and the supplier.1.2 This specification specifies the terminology,definitions,general requirements,and physical requirements for finishedwoven glass fabrics This specification permits the applicationof sizing materials to the glass fiber yarn during manufacturethat helps facilitate weaving.These organic materials aretypically removed from the greige fabric and replaced with afinish that is compatible with the resin matrix specified in thecontracting documentNOTE1Sizing 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 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.1.4 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,Glass Finished for Resin Laminates.1.5 AdditionalASTM specifications in this series have beendrafted and appear in current editions of the Annual Book ofASTM Standards.These include greige glass fabrics,glasstapes,glass sleevings,glass cords,glass sewing threads,andfinished laminates made from finished glass fabrics.1.6 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 StrandsD1059 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 MaterialsD2408 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-Functionsl 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)ofFabricD4963 Test Method for Ignition Loss of Glass Strands andFabrics1This 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.1,2010.Published January 2010.Originallyapproved in 1981.Last previous edition approved in 2009 as D4029 09.DOI:10.1520/D4029-10.2For 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 D5035 Test Method for Breaking Force and Elongation ofTextile Fabrics(Strip Method)D7018 Terminology Relating to Glass Fiber and Its Products2.2 ANSI Standard:ANSI/ASQC Z1.4 Sampling Procedures for Inspection byAttributes42.3 Military Standard and Specifications:MIL-Y-1140H Yarn,Cord
