Designation:D3512/D3512M16Standard Test Method forPilling Resistance and Other Related Surface Changes ofTextile Fabrics:Random Tumble Pilling Tester1This standard is issued under the fixed designation D3512/D3512M;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 pro-pensity of a fabric to form pills and other related surfacechanges on textiles using the random tumble pilling tester.Theprocedure is generally applicable to all types of woven andknitted apparel fabrics.NOTE1For other test methods for the pilling resistance of textiles,refer to Test Methods D3511/D3511M,D3514/D3514M,and D4970/D4970M.1.2 Some fabrics that have been treated with a silicone resinmay not be satisfactorily tested by this procedure because thesilicone resin may transfer onto the cork liners in the testchamber and cause erroneous results.1.3 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.1.4 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:2D123 Terminology Relating to TextilesD1776/D1776M Practice for Conditioning and Testing Tex-tilesD3511/D3511M Test Method for Pilling Resistance andOther Related Surface Changes of Textile Fabrics:BrushPilling TesterD3514/D3514M Test Method for Pilling Resistance andOther Related Surface Changes of Textile Fabrics:Elas-tomeric PadD4850 Terminology Relating to Fabrics and Fabric TestMethodsD4970/D4970M Test Method for Pilling Resistance andOther Related Surface Changes of Textile Fabrics:Mar-tindale TesterF104 Classification System for Nonmetallic Gasket Materi-als2.2 ASTM Adjuncts:12-435120-00 Set of 5 Photographic Standards for RandomTumble Pilling Test33.Terminology3.1 For all terminology related to D13.59,Fabric TestMethods,General,see Terminology D4850.3.1.1 The following terms are relevant to this standard:fuzz,pilling resistance,pills.3.2 For all other terminology related to textiles,see Termi-nology D123.4.Summary of Test Method4.1 Pilling and other changes in surface appearance,such asfuzzing,that occur in normal wear are simulated on a labora-tory testing machine.Pills are caused to form on fabric by arandom rubbing action produced by tumbling specimens in acylindrical test chamber lined with a mildly abrasive material.To form pills with appearance and structure that resemble thoseproduced in actual wear,small amounts of short-length graycotton fiber are added to each test chamber with the specimens.The degree of fabric pilling is evaluated by comparison of thetested specimens with visual standards that may be actualfabrics,or photographs of fabrics,showing a range of pillingresistance.The observed resistance to pilling is reported usingan arbitrary rating scale.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 1,2016.Published July 2016.Originally approvedin 1976.Last previous edition approved in 2014 as D3512 10(2014).DOI:10.1520/D3512-16.2For 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.3Available from ASTM International Headquarters.Order Adjunct No.ADJD3512.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Significance and Use5.1 Acceptance TestingThis method of testing fabrics forresistance to pilling is not recommended for acceptance testing.If it is used for acceptance testing,it should be used withcaution because the between-laboratory precision is poor.Insome cases the purchaser and the supplier may have to test acommercial shipment of one or more specific materials by thebest available test method,even though the test method is notrecommended for acceptance testing.5.1.1 If there are differences or practical significance be-tween reported test results for two laboratories(or more),comparative tests should be performed to determine if there isa statistical bias between them,using competent statisticalassistance.As a minimum,the test samples should be used thatare as homogeneous as
