Designation:D393515Standard Classification System and Basis for Specification forPolycarbonate(PC)Unfilled and Reinforced Material1This standard is issued under the fixed designation D3935;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 and reinforcedpolycarbonate and polycarbonate copolymer materials suitablefor injection molding,blow molding,and extrusion.Some ofthese compositions may also find use for compression moldingor application from solution.This classification system allowsfor the use of recycled materials provided that all specificationrequirements are met.1.2 The properties in this classification system are thoserequired for identifying the compositions covered.Other re-quirements necessary for identifying particular characteristicsimportant to specific applications are normally specified byusing the suffixes in accordance with Section 5.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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 should be made by those having expertise in theplastic field only after 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 in this standard.NOTE1This classification system and ISO 7391-1 and ISO 7391-2address the same subject matter,but differ in technical content.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 safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability or regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2D256 Test Methods for Determining the Izod PendulumImpact Resistance of PlasticsD638 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-ticsD2584 Test Method for Ignition Loss of Cured ReinforcedResinsD3892 Practice for Packaging/Packing of PlasticsD4000 Classification System for Specifying Plastic Materi-alsD5630 Test Method for Ash Content in PlasticsD7209 Guide for Waste Reduction,Resource Recovery,andUse of Recycled Polymeric Materials and Products(With-drawn 2015)3E29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE169 Practices for General Techniques of Ultraviolet-VisibleQuantitative Analysis2.2 ISO Standard:4ISO 7391-1 PlasticsPolycarbonate Molding and ExtrusionMaterials(Part 1:Designation2006)ISO 7391-2 PlasticsPolycarbonate Molding and Extrusion1This standard is under the jurisdiction of ASTM Committee D20 on Plasticsand is the direct responsibility of Subcommittee D20.15 on Thermoplastic Materi-als.Current edition approved May 15,2015.Published June 2015.Originallyapproved in 1980.Last previous edition approved in 2009 as D3935-09.DOI:10.1520/D3935-15.2For 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,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 Materials(Part 2:Preparation of Test Specimens andDetermination of Properties)3.Terminology3.1 DefinitionsThe terminology used in this classificationsystem is in accordance with Terminologies D883 and D1600.The polycarbonate materials are to be designated PC asspecified in Te
