Designation:D100210Standard Test Method forApparent Shear Strength of Single-Lap-Joint AdhesivelyBonded Metal Specimens by Tension Loading(Metal-to-Metal)1This standard is issued under the fixed designation D1002;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,relativehumidity,length of time,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,method of applying pressure(pressure bag,press platens,etc.),heat-up rate,and thetemperature of the assembly when under pressure.It should be stated whether this temperature is thatof the bondline 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 appar-ent shear strengths of adhesives for bonding metals when testedon a standard single-lap-joint specimen and under specifiedconditions of preparation and test.1.2 The values stated in SI units are considered to be thestandard.The values given in parentheses are for informationonly.1This 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 Oct.1,2010.Published October 2010.Originallyapproved in 1949.Last previous edition approved in 2005 as D1002 05.DOI:10.1520/D1002-10.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 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:2A109/A109M Specification for Steel,Strip,Carbon(0.25Maximum Percent),Cold-RolledA167 Specification for Stainless and Heat-ResistingChromium-Nickel Steel Plate,Sheet,and Strip(With-drawn 2014)3B36/B36M Specification for Brass Plate,Sheet,Strip,AndRolled BarB152/B152M Specification for Copper Sheet,Strip,Plate,and Rolled BarB209 Specification for Aluminum and Aluminum-AlloySheet and PlateB265 Specification for Titanium and Titanium Alloy Strip,Sheet,and PlateD907 Terminology of AdhesivesD4896 Guide for Use of Adhesive-Bonded Single Lap-JointSpecimen Test ResultsE4 Practices for Force Verification of Testing MachinesE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Terminology3.1 DefinitionsMany terms in this test method are definedin Terminology D907.4.Significance and Use4.1 This test method is primarily comparative.However,itdoes have application as a discriminator in determining varia-tions in adherend surface preparation parameters and adhesiveenvironmental durability.The test method has found applica-tions in controlling surface preparations,primer,and adhesivesystems for determining strength properties of tested systems.4.2 The misuse of strength values obt
