Designation:D4685/D4685M15(Reapproved 2020)Standard Test Method forPile Fabric Abrasion1This standard is issued under the fixed designation D4685/D4685M;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 covers the determination of the abra-sion of pile fabrics when the loss of pile tuffs occur,sometimescalled pile retention or pile pull out.It includes two procedures:1.1.1 Procedure AThe“Heavy Duty”procedure describesthe test option for fabrics over 240 g/m2(7 oz/yd2)or fabricswhich should meet heavy duty end-use conditions of wear.1.1.2 Procedure BThe“Light Duty”procedure describesthe test option for fabrics under 240 g/m2(7 oz/yd2)or fabricswhich should meet light duty end-use conditions of wear.1.2 The test method is intended for both regular,riblesswoven corduroy or other woven pile fabric constructions.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 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 TextilesD1776 Practice for Conditioning and Testing TextilesD2724 Test Method for Bond Strength of Bonded,Fused,and Laminated Apparel FabricsD3884 Guide for Abrasion Resistance of Textile Fabrics(Rotary Platform,Double-Head Method)D4850 Terminology Relating to Fabrics and Fabric TestMethodsE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 ASTM Adjunct:3Photographic Scale for Pile Retention2.3 AATCC Method:4TM 135 Dimensional Changes of Fabrics after Home Laun-dering3.Terminology3.1 For all terminology related to D13.59 on Fabric TestMethods,General,see Terminology D4850.3.2 The following terms are relevant to this standard:abrasion,corduroy,pile fabric,pile retention,velveteen.3.3 For definitions of all other textile terms see TerminologyD123.4.Summary of Test Method4.1 Test specimens are exposed to a specified number ofabrasion cycles on face and back separately and then evaluatedby viewing the specimen over a light box and comparing tophotographic standards.The method measures only the amountof pile pulled out of the base fabric structure and not thesurface pile appearance attributes,such as crushed or flattenribs.5.Significance and Use5.1 This test method is considered satisfactory for qualitycontrol testing and commercial shipment acceptance.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 1,2020.Published July 2020.Originally approvedin 1987.Last previous edition approved in 2015 as D4685/D4685M 15.DOI:10.1520/D4685_D4685M-15R20.2For 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.3A set of six photographic standards for pile retention of corduroy fabrics isavailable from ASTM International Headquarters.Order Adjunct No.ADJ4685.4Available 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.5.1.1 In case of a dispute arising from differences inreported test results when using this test method,the purchaserand the supplier should conduct comparative tests to determineif there is a statistical bias between thei
