Designation:C136907(Reapproved 2014)Standard Specification forSecondary Edge Sealants for Structurally Glazed InsulatingGlass Units1This standard is issued under the fixed designation C1369;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,liquid-applied,single or multi-component,chemically curing,elastomeric sealants used as the secondary seal of sealedinsulating glass units,hereinafter referred to as the“sealant”(see Fig.1).These sealants are intended to be a structuralcomponent of sealed insulating glass(IG)units used instructural sealant glazing(hereinafter referred to as SSG).Typical designs and considerations can be found in GuideC1249.Presently only certain silicone sealants are recognizedas having the necessary durability for use as secondary sealantin IG units in SSG applications.1.2 This specification does not describe all of the necessaryproperties of the sealant.Only those properties for which thereare ASTM test methods and industry-agreed-upon minimumacceptable test requirements are described by this specification.Additional properties will be added as ASTM test methods forthese properties become available.1.3 This specification only addresses the durability of thesecondary edge sealants for structurally glazed insulating glassunits.Durability of sealed insulating glass units can be found inspecifications and guides that reside within ASTM CommitteeE06.1.4 The committee with jurisdiction for this standard is notaware of any comparable standard published by other organi-zations.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationpurposes only.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 SealantsC1135 Test Method for Determining Tensile Adhesion Prop-erties of Structural SealantsC1184 Specification for Structural Silicone SealantsC1249 Guide for Secondary Seal for Sealed Insulating GlassUnits for Structural Sealant Glazing ApplicationsC1265 Test Method for Determining the Tensile Propertiesof an Insulating Glass Edge Seal for Structural GlazingApplications3.Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof the following terms used in this specification:chemicallycuring sealant,compatibility,cure,cured,elastomeric,hardness,non-sag sealant,sealant,shelf life,silicone sealant,and substrate.4.Classification of Sealants4.1 A sealant qualifying under this specification shall beclassified as to type and use as follows:4.1.1 Type SA single-component sealant.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 1997.Last previous edition approved in 2007 as C136907.DOI:10.1520/C1369-07R14.2For 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 4.1.2 Type MA multi-component sealant.4.1.3 Use GA sealant that meets the requirements of thisspecification when tested on clear,uncoated float glass sub-strates.4.1.4 Use OA sealant that meets the requirements of thisspecification when tested on coatings3such as reflective andlow-emissivity metallic materials applied to glass substrates.5.Materials and Manufacture5.1 Sealant:5.1.1 Furnish single-component sealants as a homogeneousmixture of a consistency suitable for application.Apply thesealant in strict accordance with the written recommendationsof the sealant manufacturer.The cured sealant shall be anelastomeric solid.5.1.2 Multi-component sealants shall be mixed in the cor-rect ratio4of components and delivered by appropriate equip-ment as specified by the sealant manufacturer.6.Requirements6.1 The physical,mechanical,and performance propertiesof the sealant shall conform to the requirements described inTable 1.6.2 The standard substrate for this specification is clear,uncoated float glass.If metallic coated5glass substrates are tobe qualified by
