Designation:D106208(Reapproved 2015)Standard Test Method forCleavage Strength of Metal-to-Metal Adhesive Bonds1This standard is issued under the fixed designation D1062;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.INTRODUCTIONThe accuracy of the results of strength tests of adhesive bonds will depend on the conditions underwhich the bonding process is carried out.Unless otherwise agreed upon by the manufacturer and thepurchaser,the bonding conditions shall be prescribed by the manufacturer of the adhesive.In order toensure that complete information is available to the individual conducting the tests,the manufacturerof the adhesive shall furnish numerical values and other specific information for each of the followingvariables:(1)Procedure for preparation of surfaces prior to application of the adhesive,the cleaning anddrying of metal surfaces,and special surface treatments such as sanding that are not specificallylimited by the pertinent test method.(2)Complete mixing directions for the adhesive.(3)Conditions for application of the adhesive,including the rate of spread or thickness of film,number of coats to be applied,whether to be applied to one or both surfaces,and the conditions ofdrying where more than one coat is required.(4)Assembly conditions before application of pressure,including the room temperature,length oftime,and whether open or closed assembly is to be used.(5)Curing conditions,including the amount of pressure to be applied,the length of time underpressure,and the temperature of the assembly when under pressure.State whether this temperature isthat of the bond line or of the atmosphere at which the assembly is to be maintained.(6)Conditioning procedure before testing,unless a standard procedure is specified,including thelength of time,temperature,and relative humidity.Arange may be prescribed for any variable by the manufacturer of the adhesive if it can be assumedby the test operator that any arbitrarily chosen value within such a range or any combination of suchvalues for several variables will be acceptable to both the manufacturer and the purchaser of theadhesive.1.Scope1.1 This test method covers the determination of the com-parative cleavage properties of adhesive bonds when tested onstandard shape metal specimens under specified conditions ofpreparation and testing.It may be used also to compareadhesives used with other metallic materials having anyspecified surface treatment.1.2 The values stated in SI units are to be regarded as thestandard.The values in parentheses are for information only.1.3 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:2B16/B16M Specification for Free-Cutting Brass Rod,Barand Shapes for Use in Screw Machines1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.80 on MetalBonding Adhesives.Current edition approved April 1,2015.Published April 2015.Originallyapproved in 1949.Last previous edition approved in 2008 as D1062 08.DOI:10.1520/D1062-08R15.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 B133 Specification for Copper Rod,Bar,And Shapes(With-drawn 1994)3B139/B139M Specification for Phosphor Bronze Rod,Bar,and ShapesB211 Specification for Aluminum and Aluminum-AlloyRolled or Cold Finished Bar,Rod,and WireD907 Terminology of Adhesives2.2 Other Documents:AISI 1020 Steel Code Tables43.Terminology3.1 DefinitionsMany of the terms in this test method aredefined in Terminology D907.3.2 Definitions of Terms Specific to This Standard:3.2.1 contact failure,nin characterizing the locus of anadhesive joint failure,the lack of adhesive being in contactwith the substrate.3.2.1.1 DiscussionContact failure may be due to condi-tions such as uneven surfaces,poor pressure distribution,orinsufficient adhesive in the bondline.4.Apparatus4.1 Use a testing machine capable of maintaining the rate ofloading specified in 8.2,and consisting essentially of thefollowing:4.1.1 Fixed MemberA fixed or essentially stationarymember,carrying one grip.4.1.2 Movable Member,carrying a second grip.4.1.3 Grips,for holding a test specime
