Designation:C113515Standard Test Method forDetermining Tensile Adhesion Properties of StructuralSealants1This standard is issued under the fixed designation C1135;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.1.Scope1.1 This test method covers a laboratory procedure forquantitatively measuring the tensile adhesion properties ofstructural sealants,hereinafter referred to as the“sealant”.1.2 The values stated in SI(metric)units are to be regardedas the standard.The inch-pound values given in parentheses areprovided 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.NOTE1Two ISO standards are known that develop similar informa-tion to C1135;ISO 8339 and ISO 8340.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and Sealants2.2 ISO Standards:3ISO 8339 Determination of Tensile PropertiesISO 8340 Determination of Tensile Properties at MaintainedExtension3.Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof the following terms used in this test method:cohesivefailure,primer,sealant,spacer,standard conditions,structuralsealant,and substrate.4.Significance and Use4.1 Frequently,glass or other glazing or panel materials arestructurally adhered with a sealant to a metal framing system.The sealants used for these applications are designed to providea structural link between the glazing or panel and the framingsystem.4.2 Although this test method is conducted at one prescribedenvironmental condition,other environmental conditions andduration cycles can be employed.5.Apparatus and Materials5.1 Tensile Testing Machine,capable of producing a tensileload on the specimen at the rate of 50.8 6 5.1 mm(2.0 6 0.20in.)per minute.5.1.1 Fixed MemberA fixed or essentially stationarymember carrying one grip.5.1.2 Movable MemberA movable member carrying asecond grip.5.1.3 GripsThe grips should be suitable to firmly graspthe test fixture that holds the test specimen and should bedesigned to eliminate eccentric specimen loading.Specimenloading should be perpendicular to the substrate/sealant inter-faces.For alignment purposes,each grip shall have a swivel oruniversal joint at the end nearest to the specimen.5.1.4 Grip FixtureA fixture capable of being held by thegrips and furnishing a tensile force to the sealant specimen.5.2 Spatulas,for use in applying sealant.5.3 Caulking Gun,for extruding sealant from cartridgeswhen applicable.5.4 Substrate PanelsTwo substrates of the same finish arerequired for each test specimen.NOTE2This test method is based on identical substrates of6.3 25.4 76.2 mm(0.25 1.0 3.0 in.)clear float glass.Other sub-strates may be tested;however,consideration needs to be given tomaintaining adequate rigidity of the substrates during testing.5.5 SpacerOne piece spacer made from polytetrafluoreth-ylene(PTFE)or a suitable rigid material shall be used to whichthe test sealant will not bond.5.6 Substrate Cleaning Materials.5.7 Primer(if needed).1This 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 Dec.1,2015.Published January 2016.Originallyapproved in 1990.Last previous edition approved in 2011 as C1135 00(2011).DOI:10.1520/C1135-15.2For 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.Test Specimen6.1 Assembly:6.1.1 Prior to assembly,wipe the substrates with a clean,dry,lint-free cloth,then thoroughly clean with a solutionappropriate for the substrate material.Prior to evaporation ofthe cleaning solution,wipe the substrates dry with a clean,lint-free cloth.NOTE3The precision and bias statement is based on glass substrateswith a recommended cleaning solution of a 50 to 50 ratio isopropanol andwater.6.1.2 Apply recommended primer,if required.Then,con-struct the test specimen assemblies by forming a sealant cavity12.7 by 12.7 by 50.8 mm(0.50 by 0.50 by 2.0 in.)between twosubstrate panels(see Fig.1)with the aid of appropriate spacers.6.2 Preparation of Test Assemblies:6.2.1 Prepare a set of five test specimen assemblies for eachsealant and substrate combination being tested(
