Designation:D5375/D5375M98(Reapproved 2019)Standard Test Methods forLiner Removal at High Speeds from Pressure-SensitiveLabel Stock1This standard is issued under the fixed designation D5375/D5375M;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 These test methods cover the measurement of theadherence of the release liner to the adhesive of a pressure-sensitive adhesive label.1.2 These test methods provide means of assessing theuniformity of the adhesion to the liner of a given type ofpressure-sensitive label.The assessment may be within a sheetor roll between sheets or rolls or between production lots.1.3 Variation in the label backing,liner,liner releasecoating,adhesive,and adhesive coating weight,affect theresponse.Therefore,these methods cannot be used to pinpointthe specific cause(s)of nonuniformity.1.4 These test methods may not be appropriate to test labelshaving either relatively stiff backings or stiff liners,or backingsshowing high stretch at low forces.These characteristics willresult in a high variability of the test response that is not a trueindication of the real nature of the adhesive bond.1.5 The values stated in either SI or inch-pound units are tobe regarded separately as standard.The values stated in eachsystem may not be exact equivalents;therefore,each systemmust be used independently,without combining values in anyway.1.6 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.1.7 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:2D996 Terminology of Packaging and Distribution Environ-mentsD3715/D3715M Practice for Quality Assurance of Pressure-Sensitive TapesD4332 Practice for Conditioning Containers,Packages,orPackaging Components for TestingE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or Process3.Terminology3.1 Definitions:3.1.1 General definitions for packaging and distributionenvironments are in accordance with Terminology D996.3.2 Definitions of Terms Specific to This Standard:3.2.1 pressure-sensitive labelthe combination of facematerial,pressure-sensitive adhesive,and liner.3.2.1.1 DiscussionThe adhesive is permanently tacky andinstantly adheres to whatever surface the label is designed for.Also,defined as a self-adhering label.4.Summary of Test Methods4.1 Test Method AThe label stock is adhered to a rigidplatform with double-coated tape with the liner side up.Theliner is peeled from the adhesive at a specific rate.The liner ispeeled back over itself at 180 angle.4.2 Test Method BThe label stock is adhered to a rigidplatform with double-coated tape with the liner side up.Theliner is peeled from the adhesive at a specified rate.The lineris peeled from the label stock at an angle of 90 to the stock.5.Significance and Use5.1 These test methods are a tool for development andquality assurance use.Given a specific pressure-sensitive labeland liner and a requirement in terms of the minimum for1These 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 Aug.1,2019.Published August 2019.Originallyapproved in 1993.Last previous edition approved in 2011 as D5375/D5375M 98(2011).DOI:10.1520/D5375_D5375M-98R19.2For 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.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 maximum peel value expected for this liner removal from thelabel,the data from the test can be used in conjunction withacceptance criteria.6.Apparatus6.1 Specimen CutterThe specimen cutter shall hold twosingle-edged razor blades in parallel planes,a precise distancea
