Designation:C118414Standard Specification forStructural Silicone Sealants1This standard is issued under the fixed designation C1184;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 specification describes the properties of cold liquidapplied,single-component or multicomponent,chemically cur-ing elastomeric structural silicone sealants herein referred to asthe sealant.These sealants are intended to structurally adherecomponents of structural sealant glazing systems.1.2 Only those properties for which there are industry-agreed-upon minimum acceptable requirements,as determinedby available ASTM test methods,are described in this speci-fication.Additional properties may be added as ASTM testmethods for those properties become available.1.3 The values stated in metric(SI)units are to be regardedas the standard.The values in parentheses are for informationonly.1.4 CommitteeC24,withjurisdictionoverthisspecification,is aware of two comparable standards by otherorganizations:ETAG No.002 and the Chinese national stan-dard GB16776.2.Referenced Documents2.1 ASTM Standards:2C603 Test Method for Extrusion Rate and Application Lifeof Elastomeric SealantsC639 Test Method for Rheological(Flow)Properties ofElastomeric SealantsC661 Test Method for Indentation Hardness of Elastomeric-Type Sealants by Means of a DurometerC679 Test Method for Tack-Free Time of Elastomeric Seal-antsC717 Terminology of Building Seals and SealantsC792 Test Method for Effects of HeatAging on Weight Loss,Cracking,and Chalking of Elastomeric SealantsC794 Test Method forAdhesion-in-Peel of Elastomeric JointSealantsC1087 Test Method for Determining Compatibility ofLiquid-Applied Sealants with Accessories Used in Struc-tural Glazing SystemsC1135 Test Method for Determining Tensile Adhesion Prop-erties of Structural SealantsC1401 Guide for Structural Sealant GlazingC1442 Practice for Conducting Tests on Sealants UsingArtificial Weathering ApparatusG151 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 Materials2.2 European Organization for Technical Approvals Docu-ment:3ETAG No.002 Guideline for European Technical Approvalfor Structural Sealant Glazing Systems2.3 Chinese National Standard:4GB 167761997 Structural Silicone Sealants for Building3.Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof the following terms used in this specification:adhesivefailure,chemicallycuringsealant,cohesivefailure,compatibility,cure,elastomeric,glazing,hardness,non-sagsealant,primer,sealant,shelf life,silicone sealant,structuralsealant,standard conditions,substrate,and tooling.4.Significance and Use4.1 Not all sealants meeting this specification should bepresumed to be suitable for all applications and all substrates.This specification assists in selecting sealants that meet certainminimum standards of performance.4.2 Although this specification qualifies a sealant for use,itdoes not address the adhesion capability of the sealant for aspecific substrate nor the compatibility of the sealant with thematerials it contacts.Adhesion and compatibility characteris-tics required for specific substrates or finishes can be deter-mined by Test Method C794 for adhesion and Test MethodC1087 for compatibility.1This specification is under the jurisdiction of ASTM Committee C24 onBuilding Seals and Sealants and is the direct responsibility of Subcommittee C24.10on Specifications,Guides and Practices.Current edition approved June 1,2014.Published July 2014.Originally approvedin 1991.Last previous edition approved in 2013 as C1184 13.DOI:10.1520/C1184-14.2For 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 www.eota.be4Published May 15,2005,Implemented August 1,1997;http:/ ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.3 To properly specify a sealant for the intended use whenusing this specification,it is essential that the applicable typeand use be included.5.Classification of Sealants5.1 A sealant qualifying under this specification shall beclassified as to type and use as given in 4.1.1-4.1.4.5.1.1 Type SSingle-component sealant.5.1.2 Type MMulticomponent sealant.5.1.3 Use GA sealant that meets the requirements of thisspecification when tested on a clear,uncoated float glasssubstrate.5.1.4 Use OA sealant that meets the requiremen
