Designation:D6295/D6295M98(Reapproved 2011)Standard Test Method forDispensability of LightDuty PressureSensitive Film Tape1This standard is issued under the fixed designation D6295/D6295M;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 measurement of the forceand elongation required to dispense pressure-sensitive film tapeon a 1-in.core intended for office and stationery applicationsfrom a desk-top dispenser.1.2 The values stated in either SI or inch-pound units are tobe regarded separately as standard.The values stated in eachsystem are not exact equivalents;therefore,each system mustbe used independently of the other.1.3 This standard does not propose 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: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 Process2.2 Commercial Item Description(CID):A-A-113 Tape,Pressure-Sensitive Adhesive33.Terminology3.1 DefinitionsTerminology found in Terminology D996shall apply.3.2 Definitions of Terms Specific to This Standard:3.2.1 dispensabilitythe initial force and elongation re-quired to sever or cut off a strip of pressure-sensitive film tapefrom a roll using specific test conditions and specific bladedescribed in this test method.4.Significance and Use4.1 Pressure-sensitive film tapes are supplied in roll form.For such a tape to be useful a strip of the tape must be easilydispensed or severed from the roll by means of a cutter foundon most dispensers.This test method is a means of measuringthe ease of this severing or dispensing of the tape.4.2 This test method provides information that can be usedin material specifications for product design and qualityassurance applications.It can be used in comparing differenttape products on specific dispensing blades.4.3 This test method may be suited for office and stationeryand tapes with acetate,cellophane,or light-duty plastic back-ings.Some tapes may be shown to be difficult to dispenseunder these conditions yet are readily dispensable with otherdispensing systems.NOTE1Backings described in CID A-A-113 are typical backings.5.Apparatus5.1 Tension TesterA constant-rate-of-extension(CRE)type with load cell capacity such that the maximum expecteddispensing force does not exceed 90%of its normal limit.Ameans of moving the stressing clamp at a uniform rate of 250mm/min or 10 in./min.Test information should be displayedgraphically with a sampling rate of at least 100 data points persecond.5.2 BladeManufactured in accordance with informationgiven in Fig.1.NOTE2The blade used in models C-15,C-38,C-40,and C-41dispensers4meets these requirements.This blade has been found to besuitable for this testing.5.3 Blade Support FixtureThe test fixture,as shown inFigs.2 and 3,shall have a means of rigidly mounting the blade1This test method is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.14 on Tape andLabels.Current edition approved April 1,2011.Published April 2011.Originallyapproved in 1998.Last previous edition approved in 2004 as D6295/D6295M 98(2004).DOI:10.1520/D6295_D6295M-98R11.2For 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 General Services Administration,Federal Supply ServiceSpecifications Section(3FP-E),Suite 8100,470 East LEnfant Plaza,SW,Washington,DC 20407.4Available from Chemsultants International,9349 Hamilton Dr.,Mentor,OH440611118.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 in the tensile tester so that the land portion faces at 30 downfrom the vertical and rotates the blade 10 from the horizontal.5.4 Blade ChangeIn the normal course of events the bladeshould be changed at least every 1000 uses or when there isevidence of damage or wear.A new blade should be used forreferee testing.6.Sampling6.1 Acceptance SamplingAcceptance sampling shall be inaccordance with Practice D3715/D3715M.6.2 Sampling for Other PurposesThe sampling and thenumber of test specimens depends on the purpose of thetesting.Practice E1
