Designation:D503511(Reapproved 2015)Standard Test Method forBreaking Force and Elongation of Textile Fabrics(StripMethod)1This standard is issued under the fixed designation D5035;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers raveled strip and cut strip testprocedures for determining the breaking force and elongationof most textile fabrics.Provision is made for wet testing.1.1.1 The raveled strip test is applicable to woven fabricswhile the cut strip test is applicable to nonwoven fabrics,feltedfabrics,and dipped or coated fabrics.1.2 This test method is not recommended for knitted fabricsor for other textile fabrics which have high stretch(more than11%).NOTE1For the determination of the breaking force and elongation oftextile fabrics using the grab test and modified grab test procedures,referto Test Method D5034.NOTE2For determination of the breaking force and elongation ofsome specific types of fabrics which use the strip test,refer to Specifica-tions D579 and D580.1.3 This test method shows the values in both inch-poundunits and SI units.Inch-pound units is the technically correctname for the customary units used in the United States.SI unitsis the technically correct name for the system of metric unitsknown as the International System of Units.The values statedin either acceptable metric units or in other units shall beregarded separately as standard.The values expressed in eachsystem may not be exact equivalents;therefore,each systemmust be used independently of the other,without combining inany way.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:2D76 Specification for Tensile Testing Machines for TextilesD123 Terminology Relating to TextilesD579 Specification for Greige Woven Glass FabricsD580 Specification for Greige Woven Glass Tapes andWebbingsD629 Test Methods for Quantitative Analysis of TextilesD1776 Practice for Conditioning and Testing TextilesD4848 Terminology Related to Force,Deformation andRelated Properties of TextilesD4849 Terminology Related to Yarns and FibersD4850 Terminology Relating to Fabrics and Fabric TestMethodsD5034 Test Method for Breaking Strength and Elongation ofTextile Fabrics(Grab Test)3.Terminology3.1 For definitions of textile terms used in this test method:breaking force,elongation,tensile test,refer to TerminologyD4848.3.2 For definitions of textile terms used in this test method:constant-rate-of-extension,constant rate of load,constant rateof traverse,refer to Terminology D4849.3.3 For definitions of textile terms used in this test method:cut strip test,raveled strip test,strip test,refer to TerminologyD4850.3.4 For other textile terms used in this test method,refer toTerminology D123.4.Summary of Test Method4.1 A test specimen is clamped in a tensile testing machineand a force applied to the specimen until it breaks.Values forthe breaking force and elongation of the test specimen are1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.60 on Fabric Test Methods,Specific.Current edition approved July 1,2015.Published September 2015.Replaces striptesting sections,Sections 17 through 20,of Test Method D1682.Originallyapproved in 1990.Last previous edition approved in 2011 as D5035 11.DOI:10.1520/D5035-11R15.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 obtained from machine scales,dials,autographic recordingcharts,or a computer interfaced with the testing machine.4.2 This test method describes procedures for carrying outfabric tensile tests using four types of specimen,and threealternative types of testing machines.For reporting,use thefollowing system to identify specific specimen and machinecombinations.4.2.1 Type of specimen:4.2.1.1 1R25 mm(1.0 in.)raveled strip test4.2.1.2 2R50 mm(2.0 in.)raveled strip test4.2.1.3 1C25 mm(1.0 in.)cut strip test4.2.1.4 2C50 mm(2.0 in.)cut strip test4.2.2 Type of tensile testing machine:4.2.2.1 Econstant-rate-of-extension(CRE)4.2.2.2 Lconstant-rate-of-load(CRL)4.2.2.3 Tconstant-rate-of-traverse(CRT)4.2.3 Possible combinations can be identi
