Designation:C133002(Reapproved 2013)Standard Specification forCylindrical Sealant Backing for Use with Cold Liquid-Applied Sealants1This standard is issued under the fixed designation C1330;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 covers the basic requirements forcylindrical sealant backing to be used with cold liquid appliedsealants for use in building seals.1.2 Cylindrical sealant backing serves one or more of thefollowing functions:1.2.1 Limits the amount and depth of sealant applied into ajoint,1.2.2 Acts as a bond breaker to allow joint movementwithout undue stress to the sealant,1.2.3 Provides a form to assist the sealant in developing theproper shape factor,and1.2.4 Acts as a barrier to the flow of sealant through thejoint.1.3 The committee with jurisdiction over this standard is notaware of any comparable standards published by other ASTMcommittees or other organizations.1.4 This specification may involve hazardous materials,operations,and equipment.This standard does not purport toaddress all of the safety concerns,if any,associated with itsuse.It is the responsibility of the user of this standard toestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and SealantsC1016 Test Method for Determination of Water Absorptionof Sealant Backing(Joint Filler)MaterialC1087 Test Method for Determining Compatibility ofLiquid-Applied Sealants with Accessories Used in Struc-tural Glazing SystemsC1253 Test Method for Determining the Outgassing Poten-tial of Sealant BackingD1622 Test Method for Apparent Density of Rigid CellularPlasticsD1623 Test Method for Tensile and Tensile Adhesion Prop-erties of Rigid Cellular PlasticsD5249 Specification for Backer Material for Use with Cold-and Hot-Applied Joint Sealants in Portland-Cement Con-crete and Asphalt Joints3.Terminology3.1 DefinitionsThe definitions for the following termsused in this standard are found in Terminology C717:3.1.1 bi-cellular sealant backing,bond breaker,closed cell,joint,open cell,outgassing,seal,sealant,sealant backing,skin.4.Classification4.1 Cylindrical sealant backings are divided into threetypes.4.1.1 Type Ccylindrical flexible sealant backings com-posed predominately of closed cell material as defined inTerminology C717.4.1.2 Type Ocylindrical flexible sealant backings com-posed of predominantly open cell material as defined inTerminology C717.4.1.3 Type Bcylindrical flexible sealant backings com-posed of bi-cellular material as defined in Terminology C717.5.Significance and Use5.1 This specification is designed to give some indication asto the differences in performance for various cylindrical sealantbackings.5.2 Although this specification qualifies a cylindrical sealantbacking for use,it does not address the compatibility of thebacking with the sealants with which it will make contact.Sealant compatibility should be confirmed by the sealantmanufacturer.Compatibility characteristics of sealants in con-tact with cylindrical sealant backings can be determined byTest Method C1087.6.Test Methods6.1 Water AbsorptionTesting for water absorption shall bemade in accordance with Test Method C1016,Procedure B.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 May 1,2013.Published May 2013.Originallyapproved in 1996.Last previous edition approved in 2007 as C133002(2007).DOI:10.1520/C1330-02R13.2For 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 6.2 DensityTesting for density shall be made in accor-dance with Test Method D1622.6.3 OutgassingTesting for outgassing shall be made inaccordance with Test Method C1253.6.4 Compression Deflection and RecoveryTesting to bemade in accordance with Specification D5249.6.5 Tensile StrengthTesting for tensile strength to be madein accordance with Test Method D1623.In all cases use asample length sufficient to fit the tensile testing equipment.6.6 Use of a58in.diameter sample shall be standard.7.Sampling7.1 Samples used for testing shall be taken directly from thepackage as commercially supplied by the manufacturer.8.Physical Properties8.1 Physical properties of the cylindrical sealant backingmaterial shall conform to the requirements of Table 1.9.
