Designation:D171122Standard Terminology Relating toElectrical Insulation1This standard is issued under the fixed designation D1711;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.INTRODUCTIONThis terminology is used in connection with testing and specifying solid electrical insulatingmaterials.Modifications to this terminology,reflecting common usage,may appear in particular testmethods,material specifications,practices,or other standards.Included herein are terms pertinent togeneral applications,electrical insulating papers,mica,mica processing,processed mica forms,hookup wire insulation,and partial discharge(corona).1.Scope*1.1 This terminology standard is a compilation of technicalterms associated with testing and specifying solid electrical andelectronic insulating materials.1.2 This terminology standard shall contain all definitionsthat are balloted specifically through Subcommittee D09.94and through D09 main committee and that are of generalinterest to standards associated with electrical and electronicinsulating materials.Those definitions shall be of importanceto electrical and electronic insulating materials issues but neednot be directly associated with a specific standard under thejurisdiction of Committee D09 on Electrical and ElectronicInsulating Materials.1.3 It is intended that all definitions in this terminologystandard originating in a specific standard under the jurisdic-tion of Committee D09 be identical to definitions of the sameterms as printed in standards of originating technicalsubcommittees,with the exceptions of:(1)deletion of any partof the Discussion included in another standard that refersspecifically to the use of a term in that standard;(2)figurenumbers and corresponding references;and(3)in this termi-nology standard,a parenthetical addition of a reference to oneor more technical standards in which the term is used and theyear in which the term was added to this compilation.1.3.1 Definitions contained in this terminology standardwhich did not originate in a specific standard under thejurisdiction of Committee D09,or which originated in astandard that has since been revised or withdrawn,and thathave been appropriately balloted,shall also be included in thisterminology standard.1.4 It is permissible to include symbols as part of therepresentation of terms,where appropriate.1.5 It is not intended that this terminology standard includesymbols(except as noted in 1.4).It is also permissible toinclude acronyms and abbreviations referring directly to de-fined terms.1.6 Revisions and additions to those definitions in thisterminology standard which originate in a specific standardunder the jurisdiction of Committee D09 are to be made as aproduct of a collaborative effort between SubcommitteeD09.94 and the corresponding technical subcommittee ofCommittee D09,with Subcommittee D09.94 providing edito-rial advice to the technical subcommittees.1.7 Each definition in this terminology standard shall beaccompanied by the year in which it was first incorporated intothe standard,placed at the end in parentheses.All discussionsshall also carry a date;it is possible that the discussion date isdifferent from the definition date.1.8 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:21This terminology is under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and is the direct responsibility ofSubcommittee D09.94 on Editorial.Current edition approved Sept.1,2022.Published October 2022.Originallyapproved in 1960.Last previous edition approved in 2020 as D1711 20.DOI:10.1520/D1711-22.2For 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.1D115 Test Methods for Testing Solvent Containing Var-nishes Used for Electrical InsulationD149 Test Method for Dielectric Breakdown Vo
