Designation:D619503(Reapproved 2011)Standard Test Methods forLoop Tack1This standard is issued under the fixed designation D6195;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 These test methods cover the determination of proper-ties of a pressure-sensitive adhesive.These test methods areapplicable to those adhesives that form a bond of measurablestrength rapidly upon contact with another surface.Tack forcemay be measured as the force required to separate the adhesivefrom the adherend at the interface shortly after they have beenbrought into contact under a load equal only to the weight ofthe pressure-sensitive article(for example,tape,label,sticker,etc.)on a 1 in.2contact area.1.2 The following test methods are included:1.2.1 Test Method A(using Tensile Tester),and1.2.2 Test Method B(using Loop Tack Tester).1.3 The values stated in inch-pound units are to be regardedas the standard because the industry standard width forpressure-sensitive tape is 1 inch.The values given in paren-theses are mathematical conversions to SI units that areprovided for information only and are not considered 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:2A666 Specification for Annealed or Cold-Worked AusteniticStainless Steel Sheet,Strip,Plate,and Flat BarD907 Terminology of AdhesivesD2651 Guide for Preparation of Metal Surfaces forAdhesiveBondingE4 Practices for Force Verification of Testing MachinesE171 Practice for Conditioning and Testing Flexible BarrierPackagingE177 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 European Association for the Pre-Adhesed LabelingIndustry(FINAT)Standard:3FTM 9“Quick-Stick”Tack Measurement2.3 Tag and Label Manufacturers Institute,Inc.(TLMI)Standard:4L-IB1 TLMI Loop Tack TestL-IB2 Tensile Tester Loop Tack Test3.Terminology3.1 Definitions:3.1.1 Many of the terms found in these test methods aredefined in Terminology D907.4.Summary of Test Method4.1 These test methods involve allowing a loop of pressure-sensitive adhesive with its backing to be brought into con-trolled contact with a 1 in.2(25 by 25 mm)surface of stainlesssteel,with the only force applied being the weight of thepressure-sensitive article itself.The pressure-sensitive article isthen removed from the substrate,with the force to remove thepressure-sensitive article from the adherend measured by arecording instrument.4.2 Test Method A(using a Tensile Tester)applies when aTensile Tester is used to measure loop tack and involves the useof a loop prepared from an 7 in.(175 mm)specimen strip.4.3 Test Method B(using a Loop Tack Tester)applies whena Loop Tack Tester is used to measure loop tack and involvesthe use of a loop prepared from a 5 in.(125 mm)specimenstrip.5.Significance and Use5.1 These test methods provide a quantitative measure ofthe pressure-sensitive tack property of an adhesive.1These test methods are under the jurisdiction of ASTM Committee D10 onPackaging and are the direct responsibility of Subcommittee D10.14 on Tape andLabels.Current edition approved April 1,2011.Published April 2011.Originallyapproved in 1997.Last previous edition approved in 2003 as D6195 031.DOI:10.1520/D6195-03R11.2For 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 FINAT,Laan Copes Van Cattenburch 79,2585 EW,The Hague,Holland.4Available from TLMI,40 Shuman Blvd.,Ste.295,Naperville,IL 60563.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 These test methods are designed to measure the tackproperty of the adhesive mass.The tack of a given adhesivevaries depending on the backing(generally,stiffer backingslead to higher values).5.3 Theses test methods are suitable for quality control andresearch purposes.5.4 Test Method A(using Tensile Tester)makes use of aspecimen strip 7 in.(175 mm)in length.Both the FINAT FTM9“Quick Stick”Tack Measurement Test and the TLMI L-IB2Tensile Tester Loop Tack Test also use a specimen strip of thatlength.5.5 Test Method B(using Loop Tack Tester)makes use of aspecimen strip five in.(125 mm)in length.That is the onlylength specimen strip that fits properly in the loop tack tester.5.6 If the adhesive is not already oth
