Designation:D686511Standard Classification System and Basis for Specifications forAcrylonitrileStyreneAcrylate(ASA)andAcrylonitrileEPDMStyrene(AES)Plastics and AlloysMolding and Extrusion Materials1This standard is issued under the fixed designation D6865;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.Scope*1.1 This classification system covers ASA and AESmaterials,and ASA and AES alloys suitable for injectionmolding and extrusion.This classification system does notcover recycled ASA and AES materials,and recycled ASA andAES alloys.1.2 The properties included in this standard are thoserequired to identify the compositions covered.Other require-ments necessary to identify particular characteristics importantto specialized applications are to be specified by using thesuffixes as given in Section 5.1.3 This classification system and subsequent line callout(specification)are intended to provide a means of calling outplastic materials used in the fabrication of end items or parts.It is not intended for the selection of materials.Materialselection can be made by those having expertise in the plasticfield only after careful consideration of the design and theperformance required of the part,the environment to which itwill be exposed,the fabrication process to be employed,thecosts involved,and the inherent properties of the material otherthan those covered by this standard.1.4 The following precautionary caveat pertains only to thetest method portion,Section 11,of this classification system:This standard does not purport to address all of the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatoryrequirements prior to use.NOTE1This classification system and ISO 6402 cover the samesubject matter but are not technically equivalent.2.Referenced Documents2.1 ASTM Standards:2D883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD3892 Practice for Packaging/Packing of PlasticsD4000 Classification System for Specifying Plastic Materi-alsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications2.2 ISO Standards:3ISO 179-1 PlasticsDetermination of Charpy ImpactStrengthPart 1:Non-Instrumented Impact TestISO 291 PlasticsStandard Atmospheres for Conditioningand TestingISO 294-1 PlasticsInjection Moulding Test Specimens ofThermoplastics MaterialsPart 1:General Principles,andMoulding of Multipurpose and Bar Test SpecimensISO 306 PlasticsThermoplastic Materials Determina-tion of Vicat Softening Temperature(VST)ISO 527 PlasticsDetermination of Tensile PropertiesPart 1:General Principles and Part 2:Test Conditionsfor Moulding and Extrusion MaterialsISO 1133 PlasticsDetermination of the Melt Mass FlowRate(MFR)and the Melt Volume Flow Rate(MVR)ofThermoplasticsISO 3451-1 PlasticsDetermination of AshPart 1:Gen-eral MethodsISO 6402 PlasticsImpact-Resistant Acrylonitrile/Styrene(ASA,AES,ACS)Moulding and Extrusion materials,Excluding Butadiene-Modified MaterialsPart 1:Desig-nation System and Basis for Specification and Part 2:1This classification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved April 1,2011.Published April 2011.Originallyapproved in 2004.Last previous edition approved in 2004 as D6865-04.DOI:10.1520/D6865-11.2For 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*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 States1 Preparation of Test Specimens and Determination ofProperties3.Terminology3.1 The terminology used in this classification system is inaccordance with Terminologies D883 and D1600.4.Classification4.1 ASA and AES materials,and ASA and AES alloys areclassified into groups according to their composition.Thesegroups are subdivided into classes and grades as shown inTable ASA/AES.NOTE2An example of this classification system is given as follows:The designation ASA0111 indicates the following:ASA=acrylonitrilestyreneacrylate,as found in TerminologyD1600,01=injection molding resin(group),1=medium impact(class),and1=requirements given in Table ASA/AES(grade).4.1.1 To facilitate incorporation of future or specialmaterials,the“othe
