Designation:D160018Standard Terminology forAbbreviated Terms Relating to Plastics1This standard is issued under the fixed designation D1600;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 The purpose of this terminology is to provide uniformcontractions of terms relating to plastics.Abbreviated termi-nology has evolved through widespread common usage.Thiscompilation has been prepared to avoid both the occurrence ofmore than one abbreviated term for a given plastics term andmultiple meanings for abbreviated terms.1.2 The scope of these abbreviated terms includes plasticsterms pertaining to composition and relating to type or kindaccording to mode of preparation or principle distinguishingcharacteristics.Also included are abbreviated terms for termsrelating to copolymers,blends and alloys of plastics,andadditives such as plasticizers,fillers,etc.NOTE1A code relating to the composition of rubbers is given inPractice D1418.1.3 No attempt is made here to systematize formally ashorthand terminology for polymers.Terminology,includingnomenclature,codes,symbols,and formula designations foruse in scientific literature in the field of natural and syntheticpolymers,are being studied and standardized by the Interna-tional Union of Pure and Applied Chemistry.21.4 These abbreviated terms are by no means all-inclusiveof plastics terminology.They represent,in general,those termsthat have come into established use.Since it is recognized thatabbreviated terms serve no useful purpose unless they aregenerally accepted and used,no attempt has been made toestablish a rigorous code for devising standard abbreviatedterms.This would result in awkward departures from estab-lished usage of existing and accepted abbreviated terms andlead to cumbersome combinations in the future,which wouldnot be likely to receive widespread acceptance.The abbrevi-ated terms now in use have grown naturally out of the need forconvenient,readily comprehended shorthand for long chemicalnames.This process can be expected to continue along thenatural lines of least resistance and will serve as a basis forfurther standardization as the need arises.A general guide forthe preparation of abbreviated terms appears desirable,however,to facilitate more organized and uniform standard-ization in the future.An appendix is attached,which suggestsa uniform way to prepare abbreviated terms.1.5 Note that the uppercase letter F should be used todesignate phosphate and that other elements may also bedesignated F.1.6 An abbreviated term(FR)and code numbers are pro-vided to identify classes of materials used as flame retardantsadded to plastics.The system is provided for use in situationswhere marking of plastics products is desired.NOTE2Many of the abbreviated terms,codes,numbers,and symbolsin ISO 1043 parts 1 through 4 and in ISO/DIS 1043-4 are the same as thecorresponding item in ASTM D1600.D1600 includes a number ofabbreviated terms that are not in ISO 1043.1.7 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:3D883 Terminology Relating to PlasticsD1418 PracticeforRubberandRubberLaticesNomenclatureD1972 Practice for Generic Marking of Plastic Products(Withdrawn 2014)4E176 Terminology of Fire Standards2.2 ISO Standards:5ISO 1043-1:2001 PlasticsSymbolsPart 1:Basic Poly-mers and Their Special Characteristics1This terminology is under the jurisdiction ofASTM Committee D20 on Plasticsand is the direct responsibility of Subcommittee D20.92 on Terminology.Current edition approved Jan.1,2018.Published February 2018.Originallyapproved in 1958.Last previous edition approved in 2014 as D1600-14.DOI:10.1520/D1600-18.2“Report on Nomenclature in the Field of Macromolecules,”Journal of PolymerScience,Vol VIII,1952,pp.257277.3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.5Available 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 StatesThis international standar
