Designation:D5278/D5278M09(Reapproved 2017)Standard Test Method forElongation of Narrow Elastic Fabrics(Static-Load Testing)1This standard is issued under the fixed designation D5278/D5278M;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 test method determines the elongation characteris-tics of narrow elastic fabrics made from natural or man-madeelastomers,either alone or in combination with other textilefibers,when tested with a static load testing procedure beforeor after laundering.NOTE1For determination of similar characteristics using theconstant-rate-of-extension(CRE)type tensile testing machine,refer toTest Method D4964.NOTE2For determination of similar characteristics using theconstant-rate-of load(CRL)type tensile testing machine,refer to TestMethod D1775.1.2 The use of this test method requires the selection of,ormutual agreement upon,the effective static load at which thetest results will be determined.1.3 Laundering procedures used will be those specified inTest Method AATCC 135 for 3 washing and drying cycles.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 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,health and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD1775 Test Method for Tension and Elongation of WideElastic Fabrics(Withdrawn 2000)3D1776 Practice for Conditioning and Testing TextilesD4848 Terminology Related to Force,Deformation andRelated Properties of TextilesD4850 Terminology Relating to Fabrics and Fabric TestMethodsD4964 Test Method for Tension and Elongation of ElasticFabrics(Constant-Rate-of-Extension Type Tensile TestingMachine)2.2 AATCC Test Method:35 Dimensional Changes in Automatic Home Laundering ofWoven and Knit Fabrics43.Terminology3.1 For all terminology relating to D13.59,Fabric TestMethods,General,refer to Terminology D4850.3.1.1 For all terminology related to Force,Deformation andRelated Properties in Textiles see Terminology D4848.3.1.2 The following terms are relevant to this standard:elongation,narrow elastic fabric,static load,in textile testing.3.2 For all other terms related to textiles,see TerminologyD123.4.Summary of Test Method4.1 Conditioned test specimens,laundered or unlaundered,are suspended and subjected to a specified loading.The staticload is applied for a specified time,released,and the cyclerepeated two more times.The percent elongation is readdirectly from the scale on the apparatus.1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.59 on Fabric Test Methods,General.Current edition approved July 15,2017.Published August 2017.Originallyapproved in 1992.Last previous edition approved in 2013 as D527809(2013).DOI:10.1520/D5278_D5278M-09R17.2For 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 Association of Textile Chemists and Colorists(AATCC),P.O.Box 12215,Research Triangle Park,NC 27709,http:/www.aatcc.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 5.Significance and Use5.1 This test method is considered satisfactory for accep-tance testing of commercial shipments of narrow elastic fabricsbecause the test method is used in the trade for acceptancetesting.5.1.1 In case of a dispute arising from differences inreported test res
