Designation:D520516Standard Classification System and Basis for Specification forPolyetherimide(PEI)Materials1This standard is issued under the fixed designation D5205;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 unfilled,filled,andreinforced polyetherimide materials suitable for injectionmolding and extrusion.1.2 This classification system is not intended for the selec-tion of materials,but only as a means to call out plasticmaterials to be used for the manufacture of parts.The selectionof these materials is to be made by personnel with expertise inthe plastics field where the environment,inherent properties ofthe materials,performance of the parts,part design,manufac-turing process,and economics are considered.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 to be specified byusing suffixes as given in Section 5.1.4 Polyetherimide materials,being thermoplastic,are re-processable and recyclable.This classification system allowsfor the use of those polyetherimide materials,provided that allspecific requirements of this classification system are met.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 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.Specific precautionary statements aregiven at the end of 5.4.NOTE1There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Standards:2D149 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materialsat Commercial Power FrequenciesD150 Test Methods for AC Loss Characteristics and Permit-tivity(Dielectric Constant)of Solid Electrical InsulationD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD618 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 PositionD790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-alsD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD883 Terminology Relating to PlasticsD1238 Test Method for Melt Flow Rates of Thermoplasticsby Extrusion PlastometerD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD2863 Test Method for Measuring the Minimum OxygenConcentration to Support Candle-Like Combustion ofPlastics(Oxygen Index)D3641 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 PlasticsD5740 Guide for Writing Material Standards in the Classi-fication FormatD7209 Guide for Waste Reduction,Resource Recovery,and1This 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.1,2016.Published September 2016.Originallyapproved in 1991.Last previous edition approved in 2010 as D5205 10.DOI:10.1520/D5205-16.2For 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.*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 Use of Recycled Polymeric Materials and Products(With-drawn 2015)3E29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE662 Test Method for Specific Optical Density of SmokeGenerated by Solid Materials2.2 Military Standards:4MIL-P-46184 Plastic Molding and Extrusion Materials,Polyetherimide(PEI).MIL-M-24519 Molding Plastics,Electrical,Thermoplastic2.3 Underwriters Laboratories Standards:5UL 94 Tests for Flammability of Plastic Materials for Partsin Devices and Appliances3.Terminology3.1 DefinitionsT
