Designation:D2063/D2063M10(Reapproved 2012)Standard Test Methods forMeasurement of Torque Retention for Packages withContinuous Thread Closures Using Non-Automated(Manual)Torque Testing Equipment1This standard is issued under the fixed designation D2063/D2063M;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 evaluate the torque retention ofcontinuous thread closures on containers,with matching fin-ishes,for predetermined environmental conditions over time.1.2 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.NOTE1The SI unit system is the recommended system.1.3 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:2D996 Terminology of Packaging and Distribution Environ-mentsD3198 Test Method for Application and Removal Torque ofThreaded or Lug-Style ClosuresD3474 Practice for Calibration and Use of Torque MetersUsed in Packaging ApplicationsD4169 Practice for Performance Testing of Shipping Con-tainers and SystemsD4332 Practice for Conditioning Containers,Packages,orPackaging Components for TestingE41 Terminology Relating To ConditioningE171 Practice for Conditioning and Testing Flexible BarrierPackagingE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Terminology3.1 Definitions:3.1.1 For definitions of general packaging and distributionterms,see Terminology D996.3.1.2 For definitions of application torque and removaltorque,see Test Method D3198.3.1.3 For Definitions regarding conditioning,see Terminol-ogy E41.3.2 Definitions of Terms Specific to This Standard:3.2.1 immediate removal torqueremoval torque that ismeasured at a stated interval,from 1 to 5 min after closureapplication.3.2.2 torque retentiona comparison between removaltorque at the end of a test period and a predeterminedimmediate removal torque.4.Summary of Test Methods4.1 Test Method A:Static EvaluationAt predeterminedtime intervals,the removal torques of representative samples ofa container/continuous thread closure system,previouslystored at various environmental conditions,are measured.4.2 Test Method B:Dynamic EvaluationPractice D4169 isused to develop a uniform system of evaluating the ability ofprimary packages,in the shipping units,to withstand thedistribution environment.At the end of predetermined distri-bution cycles,the removal torques of representative samples ofa container/continuous thread closure system are measured.5.Significance and Use5.1 This test method allows for the measurement of thetorque retention properties of container/continuous thread clo-sure systems of various designs,materials,and manufacture,and is suitable for packaging development and engineeringevaluation.1These test methods are under the jurisdiction of ASTM Committee D10 onPackaging and are the direct responsibility of Subcommittee D10.32 on Consumer,Pharmaceutical,Medical,and Child Resistant Packaging.Current edition approved April 1,2012.Published May 2012.Originallyapproved in 1991.Last previous edition approved in 2010 as D2063/D2063M 09(2010).DOI:10.1520/D2063_D2063M-10R12.2For 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 States1 5.2 This test method can be used for the evaluation ofcontainer/continuous thread closure systems under controlledconditions(where the application torque is known and theapplied downward force to the closure is zero).5.3 This test method measures torque retention properties ofcontainer/continuous thread closure systems with the use of anon-automated,spring torque-meter(with either a dial indica-tor or a digital readout)or a torque wrench.6.Apparatus6.1 Non-automated Spring Torque Meter,with an appropri-ate scale that accurately measures within the expected torquerange for the particular container/continuous thread closuresystem to be evaluated.6.1.1 Torque meter,if used,will have a scale where theanticipated torque readings are not less than one-third of themaximum range of the scale for the container/continuousthread c
