Designation:D316710(Reapproved 2017)Standard Test Method forFloating Roller Peel Resistance of Adhesives1This standard is issued under the fixed designation D3167;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.INTRODUCTIONThe purpose of this test method is to provide for the determination of the metal-to-metal peelstrength of adhesives by a method that will provide good reproducibility at low-,as well as athighstrength levels and yet allow for a simple method of test specimen preparation and testing.The 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 between the manufacturer andthe purchaser,the bonding conditions shall be prescribed by the manufacturer of the adhesive.In orderto ensure that complete information is available to the individual conducting the tests,themanufacturer of the adhesive shall furnish numerical values and other specific information for each ofthe following variables:(1)Procedure for preparation of the surfaces prior to application of the adhesive,the cleaning anddrying of metal surfaces,and special surface treatments such as sanding,which 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 and lengthof time.(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.It should be stated whether thistemperature is that of the glue 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 relativepeel resistance of adhesive bonds between one rigid adherendand one flexible adherend when tested under specified condi-tions of preparation and testing.1.2 A variation in thickness of the adherends will generallyinfluence the test values.For this reason,the thickness of thesheets used to make the test specimens shall be specified in thematerial specification.When no thickness is specified,theflexible adherend shall be 0.63 mm(0.025 in.)thick and therigid adherend shall be 1.63 mm(0.064 in.)thick.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 the1This 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 Nov.1,2017.Published November 2017.Originallyapproved in 1973.Last previous edition approved in 2010 as D3167 10.DOI:10.1520/D3167-10R17.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.1 responsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 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:2B209 Specification for Aluminum and Aluminum-AlloySheet and PlateD907 Terminology of AdhesivesD1781 Test Method for Climbing Drum Peel for AdhesivesE4 Practices for Force Verification of Testing Machines3.Terminology3.1 DefinitionsMany of the terms used in this test methodare d
