Designation:D388699(Reapproved 2015)Standard Test Method forAbrasion Resistance of Textile Fabrics(Inflated DiaphragmApparatus)1This standard is issued under the fixed designation D3886;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.1.Scope1.1 This test method2covers the determination of theresistance to abrasion of woven and knitted textile fabrics,bothconditioned and wet,using the inflated diaphragm tester.Thisprocedure is not applicable to floor coverings.NOTE1Other procedures for measuring the abrasion resistance oftextile fabrics are given in Test Methods D3884,D3885,D1175 andAATCC Test Method 93.1.2 The values stated in SI units are to be regarded asstandard;the values in English units are provided as informa-tion only and are not exact equivalents.1.3 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:3D123 Terminology Relating to TextilesD1175 Method of Test for Abrasion Resistance of TextileFabrics(Oscillatory Cylinder and Uniform Abrasion);Replaced by D 4157,D 4158(Withdrawn 1981)4D1776 Practice for Conditioning and Testing TextilesD2904 Practice for Interlaboratory Testing of a Textile TestMethod that Produces Normally Distributed Data(With-drawn 2008)4D2906 Practice for Statements on Precision and Bias forTextiles(Withdrawn 2008)4D3884 Guide for Abrasion Resistance of Textile Fabrics(Rotary Platform,Double-Head Method)D3885 Test Method for Abrasion Resistance of TextileFabrics(Flexing and Abrasion Method)D4850 Terminology Relating to Fabrics and Fabric TestMethods2.2 AATCC Standard:Test Method 93 Abrasion Resistance of Fabrics:AcceleratorMethod53.Terminology3.1 For all terminology related to D13.60,Fabric TestMethods,Specific,see Terminology D4850.3.2 The following term is relevant to this standard:abrasion.3.3 For definitions of all other textile terms see TerminologyD123.4.Summary of Test Method4.1 A specimen is abraded by rubbing either unidirection-ally or multidirectionally against an abradant having specifiedsurface characteristics.A specimen is held in a fixed positionand supported by an inflated rubber diaphragm which is heldunder constant pressure.A specimen is abraded by rubbingeither unidirectionally or multidirectionally against an abradanthaving specified surface characteristics.The resistance toabrasion is determined using Option 1,the number of cycles towear a hole in the specimen,or Option 2,visual assessment ofthe specimen surface after a specified number of cycles.5.Significance and Use5.1 The measurement of the resistance to abrasion of textileand other materials is very complex.The resistance to abrasionis affected by many factors,such as the inherent mechanicalproperties of the fibers;the dimensions of the fibers;thestructure of the yarns;the construction of the fabrics;and thetype,kind,and amount of finishing material added to the fibers,yarns,or fabric.1This 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.Originallyapproved in 1980.Last previous edition approved in 2011 as D3886 99(2011)1.DOI:10.1520/D3886-99R15.2This test method is based upon the development described by R.G.Stoll,in“Improved Multipurpose Abrasion Test and Its Application for the Wear Resistanceof Textiles,”Textile Research Journal,July 1949,p.394.3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.5Available from American Association of Textile Chemists and Colorists,P.O.Box 12215,Research Triangle Park,NC 27709.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 The resistance to abrasion is also greatly affected by theconditions of the tests,such as the nature of abradant,variableaction of the abradant over the area of specimen abraded,thetension of the specimen,the pressure between the specimenand abradant,and the dimensional changes in the specimens.5.3 Abrasion tests are all subject to variation due to changesin the abradant during specific tests.The abradant mustaccordingly be discarded at frequent intervals or checkedperiodically against a standard.With disposable abradants,theabradant is used only once
