Designation:D536213(Reapproved 2018)Standard Test Method forSnagging Resistance of Fabrics(Bean Bag)1This standard is issued under the fixed designation D5362;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 method determines the snagging resistance of afabric.1.2 Studies of fabric snagging have shown that this testmethod is suitable for a range of woven and knitted fabricsmade from textured or untextured filament yarns or spun yarnsor combinations of these yarns.2,3This test method is notsuitable for(1)open construction fabrics(such as a net)because the pins in the test chamber will snag the bean bagrather than the specimen,(2)heavy or stiff fabrics that cannotbe made into a cover for the bean bag,and(3)tufted ornonwoven fabrics because the apparatus is designed for wovenand knitted fabrics.1.3 The values stated in either acceptable metric units or inother units shall be regarded separately as standard.The valuesstated in each system may not be the exact equivalents;therefore,each system must be used independently of the other,without combining values in any way.In case of refereedecisions the metric units will prevail.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.Specific precautionary statements are given in Section 7.1.5 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:4D123 Terminology Relating to TextilesD1335 Test Method for Tuft Bind of Pile Yarn FloorCoveringsD1776 Practice for Conditioning and Testing TextilesD2724 Test Methods for Bonded,Fused,and LaminatedApparel FabricsD3136 Terminology Relating to Care Labeling for Apparel,Textile,Home Furnishing,and Leather ProductsD3939 Test Method for Snagging Resistance of Fabrics(Mace)D4467 Practice for Interlaboratory Testing of a Textile TestMethod That Produces Non-Normally Distributed Data(Withdrawn 2010)5D4850 Terminology Relating to Fabrics and Fabric TestMethods2.2 AATCC Standards:665 Test Method for Snag Resistance of Womens NylonHosiery(see Note 1)135 Test Method for Dimensional Changes in AutomaticHome Laundering of Woven and Knit FabricsNOTE1In 1988 the AATCC voted to withdraw this test method fromtheir technical manual;however,theASTM task group on fabric snaggingdecided it should be listed as an alternative for testing open constructionfabrics.3.Terminology3.1 Definitions:3.1.1 For definitions of textile terms used in this testmethod:color contrast,in textiles;distortion in fabrics;protrusion,in fabrics;snag,in fabrics;snagging resistance,infabrics;refer to Terminology D4850.3.1.2 For definitions of other textile terms used in this testmethod,refer to Terminology D123.1This 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 1,2018.Published August 2013.Originallyapproved in 1993.Last previous edition approved in 2013 as D5362 13.DOI:10.1520/D5362-13R18.2Stuckey,W.C.,and El Shiekh,A.,“Snags in Snag Testing of Knits”,in Senseand Nonsense in Knit Testing,American Association of Textile Chemists andColorists,1975,pp.4553.3Cary,R.T.,“Bean Bag Snag Tester:A System of Evaluation,”Textile ResearchJournal,Vol 51,No.2,1981,pp.6163.4For referenced ASTM standards,visist the ASTM Web Site,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 web site.5The last approved version of this historical standard is referenced onwww.astm.org.6Available 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 4.Summary of Test Method4.1 A fabric specimen is made into a cover for a bean bag.Then the specimen and bean ba
