Designation:C138216Standard Test Method forDetermining Tensile Adhesion Properties of Sealants WhenUsed in Exterior Insulation and Finish Systems(EIFS)Joints1This standard is issued under the fixed designation C1382;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 describes a laboratory procedure formeasuring tensile adhesion properties of sealants to exteriorinsulation and finish systems(EIFS)under dry,wet,frozen,heat-aged,and artificial weather-aged conditions.1.2 The committee with jurisdiction over this standard is notaware of any comparable standards published by other orga-nizations.1.3 The values stated in SI units are to be regarded as thestandard.The inch-pound values given in parentheses areprovided for information only.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.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and SealantsC1135 Test Method for Determining Tensile Adhesion Prop-erties of Structural SealantsC1442 Practice for Conducting Tests on Sealants UsingArtificial Weathering ApparatusE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE2110 Terminology for Exterior Insulation and Finish Sys-tems(EIFS)G113 Terminology Relating to Natural and Artificial Weath-ering Tests of Nonmetallic MaterialsG151 Practice for Exposing Nonmetallic Materials inAccel-erated Test Devices that Use Laboratory Light SourcesG154 Practice for Operating Fluorescent Ultraviolet(UV)Lamp Apparatus for Exposure of Nonmetallic MaterialsG155 Practice for Operating Xenon Arc Light Apparatus forExposure of Non-Metallic Materials3.Terminology3.1 Definitions:3.1.1 Refer to Terminology C717 for definitions of termsused in this test method,including but not limited to thefollowing:adhesion failure,cohesive failure,primer,sealant,standard conditions,and substrate.3.1.2 Refer to Terminology G113 for definitions of termsrelating to natural and artificial weathering.3.2 Description of Terms Specific to This Standardrefer toTerminology E2110 for definitions of the following terms usedin this test method:base coat,EIFS,and finish coat.4.Summary of Test Method4.1 This test method is a modification of Test MethodC1135.Preliminary testing using Test Method C794 may behelpful as a screen test to determine dry adhesion capabilitiesand priming requirements before proceeding with this test.This test is performed after the specimen assemblies aresubjected to a variety of conditions that artificially acceleratethe effect of weathering impact on the sealant-to-EIFS bond.The conditioning employed in this test does not necessarilyaddress all field conditions.5.Significance and Use5.1 EIFS are barrier-type systems that must be weather-proofed to prevent the passage of moisture,air,dust,heat,andcold from entering a structure.5.2 This test method is intended to determine the adhesionproperties of the sealant with the EIFS substrate as determinedby its tensile adhesive properties for dry,wet,frozen,heat-aged,and artificial weather-aged conditions.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 June 1,2016.Published July 2016.Originally approvedin 1997.Last previous edition approved in 2011 as C138211.DOI:10.1520/C1382-16.2For 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 6.Apparatus and Materials6.1 Tensile Testing MachineCapable of producing a ten-sile load on the specimen at the rate of 506 5 mm(2.0 6 0.20in.)/min.,and with a recording chart to show stress/strainvalues(tensile modulus).6.1.1 Fixed MemberA fixed or essentially stationarymember carrying one grip.6.1.2 Movable MemberA movable member carrying asecond grip.6.1.3 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.6.1.4 Grip FixtureA fixtur
