Designation:C156415Standard Guide forUse of Silicone Sealants for Protective Glazing Systems1This standard is issued under the fixed designation C1564;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 guide covers the use of silicone sealants in protec-tive glazing systems for building construction.Protectiveglazing includes systems designed for use in applicationssubject to natural disasters such as hurricanes,earthquakes,windstorms and forms of forced entry such as blasts,burglary,and ballistic attack.1.2 While other glazing accessories and components areused in protective glazing,this document specifically describesthe use of silicone sealants for protective glazing systems.1.3 This guide provides information useful to designprofessionals,architects,manufacturers,installers,and othersfor the design and installation of silicone sealants for protectiveglazing systems.1.4 A silicone sealant is only one component of a glazingsystem.A glazing system that meets the testing and coderequirement for impact glazing must successfully integrate theframe and its anchorage,glass,or other glazing materials,protective film or interlayer and silicone sealant into a highperformance system.Compliance with code or other require-ments can be determined through physical testing of theglazing system or through computer simulation.1.5 Glazing systems using silicone sealants that have suc-cessfully met the test requirements for missile impact andbomb blast test requirements incorporate the use of siliconesealants specifically formulated,tested,and marketed for thisapplication.Sealants that are commonly used today complywith Specifications C920 and C1184.1.6 This guide does not discuss sealants intended to protectagainst radioactivity or provide biological containment.1.7 The committee with jurisdiction over this standard is notaware of any comparable standards published by other orga-nizations.1.8 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 requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and SealantsC719 Test Method for Adhesion and Cohesion of Elasto-meric Joint Sealants Under Cyclic Movement(HockmanCycle)C794 Test Method forAdhesion-in-Peel of Elastomeric JointSealantsC920 Specification for Elastomeric Joint SealantsC1087 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 SealantsC1184 Specification for Structural Silicone SealantsC1193 Guide for Use of Joint SealantsC1394 Guide for In-Situ Structural Silicone Glazing Evalu-ationC1401 Guide for Structural Sealant GlazingC1472 Guide for Calculating Movement and Other EffectsWhen Establishing Sealant Joint WidthD624 Test Method for Tear Strength of Conventional Vul-canized Rubber and Thermoplastic ElastomersE631 Terminology of Building ConstructionsE1886 Test Method for Performance of Exterior Windows,Curtain Walls,Doors,and Impact Protective SystemsImpacted by Missile(s)and Exposed to Cyclic PressureDifferentialsF1642 Test Method for Glazing and Glazing Systems Sub-ject to Airblast Loadings2.2 GSA Standard:US General Services Administration(GSA)Standard TestMethod for Glazing and Window Systems Subject toDynamic Overpressure Loading31This guide is under the jurisdiction ofASTM Committee C24 on Building Sealsand Sealants and is the direct responsibility of Subcommittee C24.10 onSpecifications,Guides and Practices.Current edition approved Dec.1,2015.Published January 2016.Originallyapproved in 2003.Last previous edition approved in 2009 as C1564 04(2009).DOI:10.1520/C1564-15.2For 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.3U.S.General Services Administration(GSA),1800 F Street,NW Washington,DC 20405Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 DefinitionsRefer to Terminologies C717 and E631 fordefinitions of terms used in this guide.4.Significance and Use4.1 Guidelines are provided for the use of silicone sealantsin protective glazing.Protective glazing incorporates variousforms of glazing that are not covered in Guides C1401 andC1193.The requirements for a sealant in protective glazing aresimilar to the requirements for structural sealant glazing but forcertain
