1、Designation:D7611/D7611M131Standard 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
2、 last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorially corrected adjunct information in September 2014.1.Scope1.1 This practice stipulates the types,names,and sizes ofCode
3、s 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 value
4、s 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 and health practices and determ
5、ine the applica-bility of regulatory limitations prior to use.NOTE1There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Adjuncts:Adjunct to D7611/D7611M Standard Practice for CodingPlastic Manufactured Articles for Resin Identification23.Terminology3.1 Definitions:3.1.1 R
6、esin 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 in compliance withFig.1 and Table 1.4.Significance and Use4.1 Resin Identification Codes are used solel
7、y to identify theplastic resin used in a manufactured article.4.2 Resin Identification Codes are not“recycle codes.”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
8、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
9、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.5.R
10、equirements5.1 The Code is to be molded,formed or imprinted on themanufactured article.5.2 The Code shall be clear and legible.5.3 The size of the Code shall normally equal or exceed 12mm 12in.in height and width.NOTE2For small parts or components,it is not always possible toconform to these size re
11、quirements.In these cases,it is important tomaximize the size and legibility of the Code.5.4 The Code shall be placed in an inconspicuous locationon the manufactured article,such as the bottom or the back,where it will not be obvious to the consumer at the point ofpurchase so it does not influence t
12、he consumers buyingdecision.5.5 The Code shall be as shown in Table 1.Option A iscommonly found in North America.Option B is often foundinternationally.Either option is acceptable.5.6 The numbering system within the equilateral triangleshall correspond to the generic class of resins shown in Table1.
13、5.7 The Code with the Resin Identification Number“1”andthe Abbreviated Term“PETE”is reserved for manufacturedarticles produced from Poly(ethylene terephthalate).1This practice is under the jurisdiction ofASTM Committee D20 on Plastics andis the direct responsibility of Subcommittee D20.95 on Recycle
