Designation:D467316Standard Classification System for and Basis for SpecificationforAcrylonitrileButadieneStyrene(ABS)Plastics and AlloysMolding and Extrusion Materials1This standard is issued under the fixed designation D4673;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This classification system covers only ABS materialsand ABS alloys suitable for injection molding and extrusion.Some of these compositions are also suitable for compressionmolding.Recycle ABS and alloys will be addressed in aseparate standard.1.2 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.Materials are tobe selected by personnel with expertise in the plastics fieldwhere the economics,the environment to be encountered,theinherent properties of the materials,the part design,the partperformance required,and the manufacturing process to beemployed all enter into the selection.1.3 The properties included in this classification system arethose required to identify the compositions covered.Otherrequirements necessary to identify particular characteristicsimportant to specialized applications are addressed by usingthe suffixes given in Section 5.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 The following precautionary caveat pertains only to thetest methods portion,Section 12,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 regulatorylimitations prior to use.NOTE1This standard and ISO 2580 address the same subject matter,but differ in technical content.2.Referenced Documents2.1 ASTM Standards:2D256 Test Methods for Determining the Izod PendulumImpact Resistance of PlasticsD618 Practice for Conditioning Plastics for TestingD638 Test Method for Tensile Properties of PlasticsD648 Test Method for Deflection Temperature of PlasticsUnder Flexural Load in the Edgewise Position(With-drawn 2016)3D790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-alsD883 Terminology Relating to PlasticsD1003 Test Method for Haze and Luminous Transmittanceof Transparent PlasticsD1525 Test Method for Vicat Softening Temperature ofPlasticsD3641 Practice for Injection Molding Test Specimens ofThermoplastic Molding and Extrusion MaterialsD3892 Practice for Packaging/Packing of PlasticsD4000 Classification System for Specifying Plastic Materi-alsD5630 Test Method for Ash Content in PlasticsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications2.2 ISO Standards:4ISO 75-1 PlasticsDetermination of Temperature of De-flection Under LoadPart 1:General Test MethodsISO 75-2 PlasticsDetermination of Temperature of De-flection Under LoadPart 2:Plastics and EboniteISO 179 PlasticsDetermination of Charpy Impact Strengthof Rigid Materials1This classification system is under the jurisdiction ofASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved April 1,2016.Published April 2016.Originallypublished in 1996.Last previous edition approved in 2008 as D467302(2008).DOI:10.1520/D4673-16.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.*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 ISO 291 PlasticsStandard Atmosphere for Conditioningand TestingISO 294 PlasticsInjection Moulding Test Specimen ofThermoplastics MaterialsISO 306 PlasticsDetermination of Vicat Softening Tem-peratureISO/DIS527-1 PlasticsDeterminationofTensilePropertiesPart 1:General PrinciplesISO/DIS527-2 PlasticsDeterminationofTensilePropertiesPart 2:Testing ConditionsISO 2580-2 Acrylonitrile/Butadiene/Styrene(ABS)Mould-ing and Extrusion Materials,Part 2:Preparation of TestSpecimens and Determination of PropertiesISO 20753 PlasticsTest Specimens
