Designation:E260908Standard Test Method forOdor or Flavor Transfer or Both from Rigid PolymericPackaging1This standard is issued under the fixed designation E2609;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 This test method covers a recommended procedure forexamining odor or flavor properties or both of rigid polymericpackaging closures and fillable materials.1.2 This test method can be used for single materials orcoextruded materials that are foam molded,injection molded,blow molded,compression molded,or thermoformed poly-mers.1.3 The focus of this test method is the evaluation of moldedpolymer in terms of the transfer of package-related odors,flavors,or both,to water and other model systems(bland foodsimulants).Rigid packaging forms vary considerably in type,size,and shape.Thus,customizing the exact procedure fordealing with the physical requirements for individual packagesis the responsibility of the user.1.4 This test method assumes testing of the materials at aone-time point;shelf-life testing is not included.1.5 Refer to Test Method E1870 for the evaluation ofinherent odor of packaging material by confinement tests.1.6 This test method provides sample preparation proce-dures and two methods of evaluation.1.6.1 The package performance score method allows for thecomparison of any molded polymer sample to another.1.6.2 The ranking method allows for comparison of sampleswithin the currently tested set only.1.6.3 The preparation of samples is consistent regardless ofthe method of evaluation used.1.7 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.8 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:2D1292 Test Method for Odor in WaterE253 Terminology Relating to Sensory Evaluation of Mate-rials and ProductsE460 Practice for Determining Effect of Packaging on Foodand Beverage Products During StorageE619 Practice for Evaluating Foreign Odors in Paper Pack-agingE1870 Test Method for Odor and Taste Transfer fromPolymeric Packaging Film3.Terminology3.1 DefinitionsFor definitions of terms relating to sensoryanalysis,see Terminology E253.3.2 Definitions of Terms Specific to This Standard:3.2.1 blow molding,vprocess of producing a hollowpolymeric part by introducing air into a parisen.3.2.2 compression molding,vprocess of compressingpolymer between two heated platens,using the heat andpressure to produce a flat sample.3.2.3 coextruded packaging,ntwo or more layers of resinextruded simultaneously and these layers may be differentresins or the same resin.3.2.4 direct contact,npackaging material in physical con-tact with test medium.3.2.5 foam molding,vprocess of producing rigid forms byexpanding foam in a closed mold using steam.3.2.6 injection molding,vprocess of forcing molten poly-mer into a mold.3.2.7 monolayer packaging,npackaging consisting of asingle layer of material or resin.1This test method is under the jurisdiction ofASTM Committee E18 on SensoryEvaluation and is the direct responsibility of Subcommittee E18.05 on SensoryApplications-General.Current edition approved April 15,2008.Published May 2008.DOI:10.1520/E2609-08.2For 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 3.2.8 package performance score(PPS),n simple calcu-lation that allows for the comparison of one rigid packagingsample to another,as long as the same battery of tests isperformed on each of the samples.3.2.8.1 DiscussionThe PPS is calculated by summing theaverage intensity score for each of the tests in the battery.ThePPS can be used to rate acceptability by comparing it to that ofknown acceptable material.3.2.9 thermoformed polymer,nprocess of heating a plasticsheet to a formable state then using air or mechanical means toshape it to the contour of a mold.3.2.10 rigid packaging,npolymer that holds its shapeafter fabrication(that is,foam molded,injection molded,blowmolded,compression molded,or thermoformed polymer).3.2.10.1 DiscussionSome end use applications are bottles,cups,tubs,lids,caps and closures.4.Summary of Test Method4.1 The potential for contamination of packaged
