Designation:D396511Standard Classification System and Basis for Specifications forRigid Acrylonitrile-Butadiene-Styrene(ABS)Materials forPipe and Fittings1This standard is issued under the fixed designation D3965;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 materials made fromonly virgin ABS polymers and blends of ABS polymerssuitable for use in the extrusion of pipe and molding of fittings.1.2 The requirements of this classification system are appli-cable only to the ABS polymers and blends of ABS polymersas classified and do not address the requirements of the finishedpipe or fittings.The applicable ASTM standard specificationfor pipe or fittings shall be consulted for their requirements.1.3 This classification system excludes ABS polymers andblends of ABS polymers made from reprocessed,regrind,reclaimed,or recycled materials.ABS rework,generated in-house by the original plastic manufacturer,may be used by thatoriginal manufacturer,provided the ABS product shippedmeets the physical and mechanical properties required by itscallout in Table 1.1.4 This classification system and subsequent line callout(specification)provides a means for describing ABS materialsused in the manufacture of pipe and fittings.It is not intendedfor the selection of materials.Material selection shall be madeby those having expertise in the plastics field after carefulconsideration of the design and the performance required of thepart,the environment to which it will be exposed,the fabrica-tion process to be employed,the inherent properties of thematerial other than those covered by this classification system,and the economics.1.5 This classification system and subsequent line callout(specification)provides for the classification of ABS polymersand blends of ABS polymers into groups based on fiveproperties:Izod impact strength at room temperature,Izodimpact strength at low temperature,deflection temperatureunder load,tensile stress at yield point,and modulus ofelasticity in tension.The properties included are those requiredto identify the ABS material by the cell classifications.NOTE1Other requirements necessary to identify particular character-istics of ABS polymers and blends of ABS polymers will be added as testmethods become available or the need is identified.NOTE2Due to pipe and fitting standards requirements a separatestandard is planned for recycled materials.NOTE3This classification system and ISO 7245-1984 are not equiva-lent.1.6 The values stated in SI units shall be the standard.Thevalues given in parentheses are for information only.1.7 The following safety hazards caveat pertains only to thetest methods portion,Section 13,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.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 PositionD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD3641 Practice for Injection Molding Test Specimens ofThermoplastic Molding and Extrusion MaterialsD3892 Practice for Packaging/Packing of PlasticsD4000 Classification System for Specifying Plastic Materi-alsD5947 Test Methods for Physical Dimensions of SolidPlastics SpecimensF412 Terminology Relating to Plastic Piping Systems1This classification system is under the jurisdiction ofASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved Sept.1,2011.Published October 2011.Originallyapproved in 1980.Last previous edition approved in 2005 as D3965-05.DOI:10.1520/D3965-11.2For 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.*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 2.2 ISO Standard:ISO 7245-1984 Pipes and Fittings of Acrylonitrile-Butadiene-Styrene(ABS)General Specification forMoulding and Extrusion Materials33.Terminology3.1
