Designation:D480094(Reapproved 2015)Standard Guide forClassifying and Specifying Adhesives1This standard is issued under the fixed designation D4800;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 guide provides a classification system for tabulat-ing the properties of adhesives suitable for holding parts orassemblies together.The use of this guide also providesinformation necessary for the development of standard speci-fications for adhesives.NOTE1This classification system may serve many of the needs ofindustries using adhesives.This guide is subject to revision as the needrequires;therefore,the latest revision should always be used.1.2 LimitationsThis classification system is intended to bea means of identifying adhesives.It is not intended for theselection of materials.Material selection should be made bythose having expertise in the adhesives field after carefulconsideration of the design and the performance required of thepart,the environment to which it will be exposed,the attach-ment process to be employed,the inherent properties of thematerial not covered in this document,and the economicfactors.1.3 This classification system is based on the premise thatadhesives can be arranged into broad generic families usingbasic properties to arrange the materials into groups,classes,and grades.1.4 In all cases where the provisions of this classificationsystem would conflict with the referenced ASTM specificationfor a particular material,the latter shall take precedence.1.5 The values stated in SI units,as detailed in IEEE/ASTMSI 10,are to be regarded as the standard.2.Referenced Documents2.1 ASTM Standards:2D907 Terminology of AdhesivesD1084 Test Methods for Viscosity of AdhesivesD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1310 Test Method for Flash Point and Fire Point of Liquidsby Tag Open-Cup ApparatusD2240 Test Method for Rubber PropertyDurometer Hard-nessD2583 Test Method for Indentation Hardness of Rigid Plas-tics by Means of a Barcol ImpressorD2834 Test Method for Nonvolatile Matter(Total Solids)inWater-Emulsion Floor Polishes,Solvent-Based FloorPolishes,and Polymer-Emulsion Floor PolishesD3278 Test Methods for Flash Point of Liquids by SmallScale Closed-Cup ApparatusD4562 Test Method for Shear Strength of Adhesives UsingPin-and-Collar SpecimenD5363 Specification for Anaerobic Single-Component Ad-hesives(AN)IEEE/ASTM SI 10 Standard for Use of the InternationalSystem of Units(SI):The Modern Metric System2.2 Military Standards:MIL-STD-105 Sampling Procedures and Tables for Inspec-tion by Attributes3MIL-A-46146 Adhesive,Silicone,RTV,Noncorrosive(forUse with Sensitive Metals and Equipment)33.Terminology3.1 The terms used in this guide are in accordance withTerminology D907.4.Significance and Use4.1 The purpose of this classification system is to provide amethod of identifying adhesives in order to give industry asystem that can be used universally for materials.It furtherprovides a means for specifying these materials by the use ofthe standards that are developed using this guide.4.2 This classification system was developed to permit theaddition of future adhesives.1This guide is under the jurisdiction ofASTM Committee D14 on Adhesives andis the direct responsibility of Subcommittee D14.60 on Adhesive Material Classi-fication System.Current edition approved Sept.1,2015.Published September 2015.Originallyapproved in 1987.Last previous edition approved in 2011 as D4800 94(2011).DOI:10.1520/D4800-94R15.2For 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 Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/dodssp.daps.dla.mil.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Classification5.1 Fig.1 summarizes the classification system as detailedin this guide.5.2 Adhesives shall be classified on the basis of their broadgeneric family.The generic family is identified by letterdesignations as found in Table 1.NOTE2For example:CA=Cyanoacrylate.5.2.1 The generic family is based on the broad chemicalmakeup of the base materials.By its designation,certaininherent properties are specified.5.3 The generic family is classified into groups according,in general,to the chemical composition.These groups arefurther subdivided into classes and grades,as shown in thebasic property table that applies.The letter designation appli-cable is followed by a four-digit number indicat
