Designation:D560319aStandard Classification forRubber Compounding MaterialsRecycled VulcanizateRubber1This standard is issued under the fixed designation D5603;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 classification covers the compounding materialcommercially known as recycled vulcanizate particulate rub-ber.Recycled vulcanizate particulate rubber is the product thatresults when vulcanizate rubber has been processed by somemeans to obtain a desired particle size distribution.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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.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:2D297 Test Methods for Rubber ProductsChemical Analy-sisD1509 Test Methods for Carbon BlackHeating LossD1566 Terminology Relating to RubberD5644 Test Method for Rubber Compounding MaterialsDetermination of Particle Size Distribution of RecycledVulcanizate Particulate RubberD8268 Practice for Rubber Compounding MaterialsEvaluation of Recycled Vulcanizate Particulate RubberE1131 Test Method for Compositional Analysis by Thermo-gravimetry3.Terminology3.1 Definitions:3.1.1 recycled vulcanizate particulate rubber,nrecyclablevulcanizate rubber that has been processed to give particulatesor other forms of different shapes,sizes,and size distributions.3.1.2 particulaterubber,nrubber,vulcanizedorunvulcanized,that has been transformed into a collection ofparticles,with or without a coating of a partitioning agent toprevent agglomeration during production,transportation,orstorage(see buffing rubber,granulated rubber,ground rubber,and powdered rubber).D15663.1.3 granulated rubber,nparticulate rubber composed ofmainly non-spherical particles that span a broad range ofmaximum“particle dimension”from below 425 m(40 mesh)to 12 mm(0.47 in.);the key feature of this type of particulaterubber is the fraction of the material in the greater than 1-mm(0.08-in.)up to 12-mm(0.47-in.)maximum“particle dimen-sion”range.D15664.Significance and Use4.1 Recycled vulcanizate particulate rubber is important inrubber compounding.It allows the rubber compounder to adda certain percentage of rubber filler back into its parent orsimilar compounds or to use the material as substitute or standalone compound.Its use may lower compound costs orimprove performance characteristics,or both.4.2 Many types of recycled vulcanizate particulate rubberare available,with the number of types of vulcanizate particu-late rubber limited only by the number of parent compounds.4.3 Recycled vulcanizate particulate rubber is used as feed-stock for thermal decomposition,devulcanization,recoveredcarbon black,tire-derived aggregate,synthetic turf infill,asphalt-rubber,molded rubber products,tire-derived fuel,andother tire and non-tire derived products and end uses.4.4 Use of recycled rubber has a positive environmentalimpact.1This classification is under the jurisdiction of Committee D11 on Rubber andRubber-like Materials and is the direct responsibility of Subcommittee D11.20 onCompounding Materials and Procedures.Current edition approved July 1,2019.Published July 2019.Originally approvedin 1996.Last previous edition approved in 2019 as D5603 19.DOI:10.1520/D5603-19A.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 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 5.Classification of Recycled Vulcanizate ParticulateRubber5.1 The classification of recycled vulcanizate particulaterubber is based on two major characteristics:the classificationof the source of rubber(Table 1)and the particle sizedistribution of the particula
