Designation:D559294(Reapproved 2018)Standard Guide forMaterial Properties Needed in Engineering Design UsingPlastics1This standard is issued under the fixed designation D5592;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.INTRODUCTIONPlastics are increasingly being used in durable applications as structural components on a basiscomparable with traditional materials such as steels and aluminum,as well as high performancecomposite systems.Unlike many consumer-goods applications,where plastics typically serve asenclosures,these durables applications primarily involve load-bearing components exposed to ratherbroad varying operating environments over the life cycle of the product.This necessitates access tomaterial property profiles over a wide range of conditions,rather than typical values reported at roomtemperature.In order to design effectively with plastics,the designer must take into account the effectsof time,temperature,rate,and environment on the performance of plastics,and the consequences offailure.1.Scope1.1 This guide covers the essential material propertiesneeded for designing with plastics.Its purpose is to raise theawareness of the plastics community regarding the specificconsiderations involved in using the appropriate materialproperties in design calculations.1.2 This guide is intended only as a convenient resource forengineering design.It should be noted that the specific oper-ating conditions(temperature,applied stress or strain,environment,etc.and corresponding duration of such expo-sures)could vary significantly from one application to another.It is,therefore,the responsibility of the user to perform anypertinent tests under actual conditions of use to determine thesuitability of the material in the intended application.1.3 The applicable ISO andASTM standard methods for therelevant material properties are listed in this guide for thebenefit of design engineers.1.4 It should be noted that for some of the desiredproperties,no ASTM or ISO standards exist.These includepvT data,no-flow temperature,ejection temperature,andfatigue in tension.In these instances,relying on available testmethods is suggested.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.NOTE1There is no known ISO equivalent to this standard.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD638 Test Method for Tensile Properties of PlasticsD695 Test Method for Compressive Properties of RigidPlasticsD883 Terminology Relating to PlasticsD1435 Practice for Outdoor Weathering of Plastics1This guide is under the jurisdiction of ASTM Committee D20 on Plastics andis the direct responsibility of Subcommittee D20.10 on Mechanical Properties.Current edition approved April 1,2018.Published April 2018.Originallyapproved in 1994.Last previous edition approved in 2010 as D5592-94(2010).DOI:10.1520/D5592-94R18.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 D1894 Test Method for Static and Kinetic Coefficients ofFriction of Plastic Film and SheetingD1999 Guide for Selection of Specimens and Test Param-eters from ISO/IEC Standards(Withdrawn 2000)3D2565 Practice for Xenon-Arc Exposure of Plastics In-tended for Outdoor ApplicationsD2990 Test Methods for Tensile,Compressive,and FlexuralCreep and Creep-Rupture of PlasticsD2991 Test Method for Stress-Relaxation of Plastics(With-drawn 1990)3D3045 Practice
