Designation:D42914Standard Test Methods forRubber PropertyAdhesion to Rigid Substrates1This standard is issued under the fixed designation D429;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.Scope1.1 These test methods cover procedures for testing thestatic adhesional strength of rubber to rigid materials(in mostcases metals).Method ARubber Part Assembled Between Two ParallelMetal Plates.Method B90 Stripping TestRubber Part Assembled toOne Metal Plate.Method CMeasuring Adhesion of Rubber to Metal with aConical Specimen.Method DAdhesion TestPost-Vulcanization(PV)Bond-ing of Rubber to Metal.Method E90 Stripping TestRubber Tank LiningAssembled to One Metal Plate.Method FRubber Part Assembled Between Two ParallelConvex-Shaped Metal PlatesMethod GMeasuring Bond Durability for Rubber-to-MetalBonded Components with a Double Shear Cylindrical Speci-menMethod HMeasuring Bond Durability for Rubber-to-MetalBonded Components with a Quadruple Shear Specimen1.2 While the test method may be used with a wide varietyof rigid materials,use of materials other than metals is theexception.For this reason,we have used the word“metal”inthe text rather than“rigid materials.”1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2B117 Practice for Operating Salt Spray(Fog)ApparatusD395 Test Methods for Rubber PropertyCompression SetD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD572 Test Method for RubberDeterioration by Heat andOxygenD573 Test Method for RubberDeterioration in an AirOvenD1149 Test Methods for Rubber DeteriorationCracking inan Ozone Controlled EnvironmentE4 Practices for Force Verification of Testing MachinesG153 Practice for Operating Enclosed Carbon Arc LightApparatus for Exposure of Nonmetallic Materials2.2 ASTM Adjuncts:Holding Fixture Drawings33.Significance and Use3.1 These test methods are designed primarily for speci-mens prepared in a laboratory under standardized conditionssuch as may be used to provide data for development andcontrol of rubber compounds and methods of manufacture.With slight modifications as indicated,Methods A,B,C,D,and E are also used for obtaining comparative adhesion testvalues of production parts whenever the design permits prepa-ration of suitable test specimens.Methods A,B,C,and D areapplicable in the case of many products in which rubber is usedfor controlling vibration.METHOD ARUBBER PART ASSEMBLEDBETWEENTWO PARALLEL METAL PLATES4.Adhesion Failure Terminology4.1 R indicates the failure is in the rubber.1These test methods are under the jurisdiction of ASTM Committee D11 onRubberand are the direct responsibility of Subcommittee D11.25 on RubberAdhesive Systems.Current edition approved May 1,2014.Published May 2014.Originallyapproved in 1935.Last previous edition approved in 2008 as D429 08.DOI:10.1520/D0429-14.2For 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.3Complete detail drawings of the fixture are available from ASTM InternationalHeadquarters.Order Adjunct No.ADJD0429.Original adjunct produced in 1959.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.2 RC indicates the failure is at the rubber-cover cementinterface.4.3 CP indicates the failure is at the cover cement-primecement interface.4.4 M(can also be denoted as CM)indicates the failure is atthe metal-prime cement interface.NOTE1ExampleThe percentages of the various types of failuremay be estimated as in the following examples:R-50,RC-50 means that roughly one half or 50%of the area showedfailure in the rubber and the other 50%showed failure at the rubber covercement interface.R-25,RC-25,M-50 means three types of failure were present with theM indicating 50%failure at the metal-primer interface.Determining thelocus of failure can normally be determined visually,but may requireanalytical test methods.5.Significance and Use5.1 Method A is used to determine adhesion values ininstances where users feel this design is more reflective of anactual product and where control tests have been set u
