Designation:D385322Standard Terminology Relating toRubber and Rubber LaticesAbbreviations for ChemicalsUsed in Compounding1This standard is issued under the fixed designation D3853;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 This terminology is a compilation of abbreviations foraccelerators,vulcanizing agents,activators,antidegradants,plasticizers,softeners,processing aids,blowing agents,retarders,isocyanates,peroxides,and antireversion agents usedin the compounding of rubber products.Abbreviations forrubbers are listed in Practice D1418 and a numbering systemfor various grades of carbon blacks is described in Classifica-tion D1765.1.2 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:2D1418 PracticeforRubberandRubberLaticesNomenclatureD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD1566 Terminology Relating to RubberD1765 Classification System for Carbon Blacks Used inRubber Products2.2 ISO Standard:3ISO6472 RubberCompoundingIngredientsAbbreviations3.Significance and Use3.1 These abbreviations are to be used in technical writingwhere the full chemical name of the substance is used initially,followed by the abbreviation found in this terminology.Laterreferences to this substance may then use the abbreviation only.4.Form and Style4.1 Although generally accepted references3,4,5for namingchemicals provide the basis for these abbreviations,commonusage has dictated the particular choice for the abbreviationsset forth in this terminology.4.2 Conventions used in this terminology are:4.2.1 The symbol B will be used for butyl in the case ofaccelerators and vulcanizing agents and for butylidene in thecase of bisphenol materials(see 4.2.6.2).4.2.2 The symbol Bz will be used for benzyl groups.4.2.3 When possible,a number will be used to denote longchain hydrocarbons,that is,5 for penta,88 for dioctyl,etc.Ifthe length of the hydrocarbon chain is ten or higher,the numbershall be placed in parenthesis,that is(12)for dodecyl,etc.Theletter“i”shall be used to denote an iso structure.4.2.4 The chemical symbol for metallic components will beused whenever possible.This will usually occur at the begin-ning of the abbreviation.4.2.5 The symbol C will be used for dithiocarbamateaccelerators and for cyclohexyl in the case of sulfenamideaccelerators and bisphenol antioxidants.4.2.6 Commercial bisphenol antioxidants are made up oftwo alkyl/cyclohexyl substituted phenol rings linked in theortho or para position.The following conventions will be usedin this nomenclature scheme:4.2.6.1 oorthommetapparaBpbisphenol structure4.2.6.2 MmethyleneBbutylideneIBisobutylideneIPisopropylideneTthio1This terminology is under the jurisdiction ofASTM Committee D11 on Rubberand Rubber-like Materials and is the direct responsibility of Subcommittee D11.08on Terminology.Current edition approved June 1,2022.Published June 2022.Originallyapproved in 1979.Last previous edition approved in 2017 as D3853 12(2017).DOI:10.1520/D3853-22.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.4A Guide to IUPAC Nomenclature of Organic Compounds,CRC Press,BocaRaton,FL,1993.5Fox,R.B.,Nomenclature of Organic Compounds,American Chemical Society,Washington,DC,2001.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.14.2.6.3 1methyl2ethyl4 t-butyl9nonylCcyclohexyl4.2.7 For diphenylamine antidegradants use numbers for theidentification of alkyl substituents on the diphenylamine rings.5.AbbreviationsACCELERATORS AND VULCANIZING AGENTSBAbutyraldehydeaniline condensate.BiDMCbismuth dimethyldithiocarbamate.BMTSbismorpholinothiocarbamyl sulfenamide.CBSN-cyclohexyl-2-benzothiazyl sulfenamide.CdDECcadmium diethyldithiocarbamate.CdDMCcadmium dimethyldithiocarbamate.Cd5MCcadmium pentamethylenedithiocarbamate.CEAcyclohexylethylamine.CuDIPcopper diisopropyldithiophosphate.CuD
