Designation:C147216Standard Guide forCalculating Movement and Other Effects When EstablishingSealant Joint Width1This standard is issued under the fixed designation C1472;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 provides information on performance factorssuch as movement,construction tolerances,and other effectsthat should be accounted for to properly establish sealant jointsize.It also provides procedures to assist in calculating anddetermining the required width of a sealant joint enabling it torespond properly to those movements and effects.Informationin this guide is primarily applicable to single-and multi-component,cold-applied joint sealants and secondarily toprecured sealant extrusions when used with properly preparedjoint openings and substrate surfaces.1.2 Although primarily directed towards the understandingand design of sealant joints for walls for buildings and otherareas,the information contained herein is also applicable tosealant joints that occur in horizontal slabs and paving systemsas well as various sloped building surfaces.1.3 This guide does not describe the selection and propertiesof joint sealants(1)2,nor their use and installation,which isdescribed by Guide C1193.1.4 For protective glazing systems that are designed to resistblast and other effects refer to Guide C1564 in combinationwith this guide.1.5 This guide is not applicable to the design of joints sealedwith aerosol foam sealants.1.6 For structural sealant glazing systems refer to GuideC1401 in combination with this guide.1.7 The values and calculations stated in SI units are to beregarded as the standard.The values given in parentheses andinch-pound units are provided for information only.SI units inthis guide are in conformance with IEEE/ASTM SI 10-1997.1.8 The Committee having jurisdiction for this guide is notaware of any comparable standards published by other orga-nizations.1.9 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:3C216 Specification for Facing Brick(Solid Masonry UnitsMade from Clay or Shale)C717 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 SealantsC1193 Guide for Use of Joint SealantsC1401 Guide for Structural Sealant GlazingC1481 Guide for Use of Joint Sealants with Exterior Insu-lation and Finish Systems(EIFS)C1518 Specification for Precured Elastomeric Silicone JointSealantsC1523 Test Method for Determining Modulus,Tear andAdhesion Properties of Precured Elastomeric Joint Seal-antsC1564 Guide for Use of Silicone Sealants for ProtectiveGlazing Systems2.2 The tables included in this guide are based on thereference version(year)outlined below.The references maynot represent the most recent version of these standards basedon publication dates and update intervals of these externalreferences.Updates to these standards may have been pub-lished at intervals inconsistent with updates to this standard.Evaluation of accurate properties and data for the materials andthe locale of the project are recommended.1This 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 July 1,2016.Published August 2016.Originallyapproved in 2000.Last previous edition approved in 2010 as C1472 10.DOI:10.1520/C1472-16.2The boldface numbers in parentheses refer to the list of references at the end ofthis standard.3For 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 2.3 American Concrete Institute(ACI),American Society ofCivil Engineers(ASCE),and The Masonry Society(TMS):4Building Code Requirements for Masonry Structures(ACI530-02/ASCE 5-02/TMS 401-02)Reported by the Ma-sonry Standards Joint Committee(MSJC)2.4 Prestressed Concrete Institute(PCI):5Manual for Quality Control for Plants and Production ofArchitectural Precast Concrete Products,MNL-177-772.5 American Society of Heating,Refrigerating and Air-Conditioning Engineers,Inc.(ASHRAE):6Chapter 27,Climatic Design I
