Designation:D7611/D7611M21Standard Practice forCoding Plastic Manufactured Articles for ResinIdentification1This standard is issued under the fixed designation D7611/D7611M;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.Scope*1.1 This practice stipulates the types,names,and sizes ofCodes for those material types specified in Table 1.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system are likely not to be exact equivalents;therefore,each system shall be used independently of the other.Combin-ing values from the two systems is likely to result in non-conformance with the standard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.NOTE1There is no known ISO equivalent to this standard.1.4 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:2D3418 Test Method for Transition Temperatures and En-thalpies of Fusion and Crystallization of Polymers byDifferential Scanning CalorimetryD4020 Specification for Ultra-High-Molecular-Weight Poly-ethylene Molding and Extrusion Materials2.2 ASTM Adjuncts:Adjunct to D7611/D7611M Standard Practice for CodingPlastic Manufactured Articles for Resin Identification33.Terminology3.1 Definitions:3.1.1 Resin Identification Code(RIC Code)a molded,imprinted or raised symbol or wording that consists of anequilateral triangle,a Resin Identification Number,and anAbbreviated Term for polymeric material.4.Significance and Use4.1 Resin Identification Codes are used solely to identify theplastic resin used in a manufactured article.The intendedmanufactured articles include,but are not limited to,packag-ing.4.1.1 Fig.1 and Table 1 present the appropriate informationon the way the RIC is to be incorporated onto the product andthe available resin identification designations.4.2 Resin Identification Codes are not“recycle codes.”TheResin Identification Code is,though,an aid to recycling.Theuse of a Resin Identification Code on a manufactured plasticarticle does not imply that the article is recycled or that thereare systems in place to effectively process the article forreclamation or re-use.The term“recyclable”or other environ-mental claims shall not be placed in proximity to the Code.4.3 This practice is based upon the system developed in1988 by the Society of the Plastics Industry,Inc(SPI).It ispossible that some states or countries will have incorporatedthe original SPI practice into statute or regulation.In thosesituations,that statute or regulation takes precedence over thisstandard.4.4 This practice shall only apply to new tooling.Existingmolds that already incorporate older versions of the SPI RICmay be modified,but modification is not required.4.5 Assign number for manufactured items,not for adhe-sives or coatings.Do not code labels for resin of the label.1This practice is under the jurisdiction ofASTM Committee D20 on Plastics andis the direct responsibility of Subcommittee D20.95 on Recycled Plastics.Current edition approved Dec.1,2021.Published January 2022.Originallyapproved in 2010.Last previous edition approved in 2020 as D7611/D7611M 20.DOI:10.1520/D7611_D7611M-21.2For 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 ASTM International Headquarters.Order Adjunct No.ADJD761114-EA.Original adjunct produced in 2010.Adjunct last revised in 2014.*A Summary of Changes section appears at the end of this standardCopyright 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?TABLE 1 Resin Identification CodesD7611/D7611M 212?4.6 Section 6 addresses the process to add new numbers tothe Resin Identification Code.5.Requirements5.1 The Code is to be molded,formed or imprinted on theman
