1、Designation:D559294(Reapproved 2010)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 o

2、f 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 traditio

3、nal 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

4、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 environm

5、ent 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 mat

6、erialproperties 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

7、 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

8、 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.

9、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-pr
