Designation:C1216/C1216M13Standard Test Method forAdhesion and Cohesion of One-Part Elastomeric SolventRelease Sealants1This standard is issued under the fixed designation C1216/C1216M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is a laboratory procedure that deter-mines the adhesion and cohesion performance of one-partelastomeric,solvent release sealants at high and low tempera-tures by the extension and compression of test specimens.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 The subcommittee with jurisdiction is not aware of anysimilar ISO standard.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.For a specificprecautionary statement,see Note 2.2.Referenced Documents2.1 ASTM Standards:2C33 Specification for Concrete AggregatesC109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50-mm CubeSpecimens)C150 Specification for Portland CementC717 Terminology of Building Seals and Sealants2.2 Aluminum Association Standard:DAF-45 Designation System for Aluminum Finishes33.Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof the following terms used in this test method:adhesivefailure,bond breaker,cohesive failure,elastomeric,joint,primer,sealant,solvent release sealant,substrate,and standardconditions.4.Significance and Use4.1 The failure of a building sealant in a joint that experi-ences movement is manifested by cohesive failure in thesealant or adhesive failure between the sealant and substrate,orboth.This test method evaluates the performance of one-partelastomeric solvent release sealants in joints subjected tomovement and temperature aging.5.Apparatus5.1 Extension-Compression Machine,as shown in Fig.1,designed to extend the test specimens automatically at aconstant rate of 3.20 mm 18in./h from a joint width of 11.2mm 716in.to 14.29 mm 916in.at 12 6 2.8C +10 65F.45.2 Oven,forced-draft type,having the temperature con-trolled to 70 6 1C 158 6 2F.5.3 Oven,convection type,having the temperature con-trolled to 50 6 1C 122 6 2F.5.4 Freezer Chest or Cold Box,having the temperaturecontrolled to 12 6 2.8C+10 6 5F.5.5 C-Clamps,or other clamping devices.6.Reagents6.1 Purity of ReagentsReagent grade chemicals shall beused in all tests.Unless otherwise indicated,it is intended that1This test method is under the jurisdiction ofASTM Committee C24 on BuildingSeals and Sealants and is the direct responsibility of Subcommittee C24.30 onAdhesion.Current edition approved May 1,2013.Published June 2013.Originallyapproved in 1992.Last previous edition approved in 2008 as C1216 03(2008).DOI:10.1520/C1216_C1216M-13.2For 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 Aluminum Association,900 19th St.NW,Washington,DC20006.4Series 520 Sealant Compound Tester,manufactured by Applied Test Systems,Inc.,348 New Castle Rd.,Butler,PA16001,and a durability tester manufactured byAmbard,Inc.,269-11 Sist Ave.,New Hyde Park,NY 11040,have been foundsuitable for this purpose.The sole source of supply of the apparatus known to the committee at this timeis Applied Test Systems and Ambard.If you are aware of alternative suppliers,please provide this information to ASTM International Headquarters.Your com-ments will receive careful consideration at a meeting of the responsible technicalcommittee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 all reagents shall conform to the specifications of the Commit-tee on Analytical Reagents of the American Chemical Society,where such specifications are available.5Other grades may beused,provided it is first ascertained that the reagent is ofsufficiently high purity to permit its use without lessening theaccuracy of the determination.6.2 Acetone or Methyl Ethyl Ketone Solvents.6.3 Detergent Solution.66.4 Distilled Water.6.5 Primer,if required.7.Sealants,Substrates,and Accessories7.1 The sealants shall be obtained from previously un-opened containers.Precondition the unopened containers ofsealant at standard conditions a
