Designation:D824820Standard Terminology forSmart Textiles1This standard is issued under the fixed designation D8248;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.Scope1.1 Smart textiles is an emerging field.As the needs of thisarea develop,this standard will evolve accordingly.Its contentmay be referenced or adopted,or both,in whole or in part asdemanded by the needs of the user.1.2 Terminology and definitions related to smart textilessuch as electrical textiles and wearable electronics will beincluded as well as the fiber,yarn,and fabric that composethem,and final end products.1.3 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.Terminology2.1 Definitions:electronic textile,na fiber,yarn,fabric or end productcomprising elements that result in an electrical or electroniccircuit,with or without processing capability,or the compo-nents thereof.(Synonyms:electromagnetic textile,e-textile,etextile.)DISCUSSIONAny combination of textiles and other componentsengineered to provide properties necessary for the creation of a circuit.metallic fiber,na manufactured fiber composed of metal,polymer-coated metal,metal-coated polymer,or a corecovered by metal which can be transformed into a yarn ormade into fabric by interlacing the strands in a variety ofmethods including weaving,knitting,braiding,felting,andtwisting.smart textile,na fiber,yarn,fabric,or end product with oneor more properties that change by design in response tostimuli,such as those from mechanical,thermal,chemical,electrical,magnetic,or other sources.(Synonyms:intelligenttextile,intelligent textile system,smart textile system.)(Seetechnical textile.)DISCUSSIONSmart fabrics differ from technical fabrics in that thefabric properties change in response to a stimulus.A thermo-chromicfabric changes color in response to the application of heat and is a smarttextile.technical textile,na broad term for fiber,yarn,fabric,or endproduct used for applications where functional performanceis of primary importance;wherein a textile provides func-tionality due to inherent material properties and/or anapplied treatment.(See smart textile.)DISCUSSIONWater repellent,flame resistant,and antimicrobial fab-rics all provide functional performance against stimuli such as rain,flames,and microbes but the fabric properties do not change inresponse to those challenges.wearable electronic,nan electronic device that is worn onthe body either as an accessory or integrated into clothing.DISCUSSIONThe device,which is usually standalone,can be perma-nently or temporarily integrated into clothing,such as a sensor.This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised,either reapproved or withdrawn.Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters.Your comments will receive careful consideration at a meeting of theresponsible technical committee,which you may attend.If you feel that your comments have not received a fair hearing you shouldmake your views known to the ASTM Committee on Standards,at the address shown below.This standard is copyrighted by ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.Individual reprints(single or multiple copies)of this standard may be obtained by contacting ASTM at the aboveaddress or at 610-832-9585(phone),610-832-9555(fax),or serviceastm.org(e-mail);or through the ASTM website(www.astm.org).Permission rights to photocopy the standard may also be secured from the Copyright Clearance Center,222Rosewood Drive,Danvers,MA 01923,Tel:(978)646-2600;http:/ terminology is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.50 on Smart Textiles.Current edition approved Feb.1,2020.Published February 2020.Originallyapproved in 2019.Last previous edition approved in 2019 as D8248-19.DOI:10.1520/D8248-20.Copyright 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.
