Designation:E269017bAn American National StandardStandard Practice forSpecimen Preparation and Mounting of Caulks and Sealantsto Assess Surface Burning Characteristics1This standard is issued under the fixed designation E2690;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 practice describes procedures for specimen prepa-ration and mounting when testing caulks and sealants to assessflame spread and smoke development as surface burningcharacteristics using Test Method E84.1.1.1 Caulks and sealants up to 8 in.(203.2 mm)in widthshall follow the requirements of 7.1.1.1.2 Caulks and sealants in excess of 8 in.(203.2 mm)inwidth shall follow the requirements of 7.2.1.1.2.1 Caulks and sealants in excess of 8 in.(203.2 mm)inwidth can be considered coatings.1.2 This practice applies to caulks and sealants intended forvarious uses within buildings.The caulks and sealants ad-dressed in this practice are not able to be supported by theirown structural characteristics during the test.1.2.1 This practice does not apply to adhesives that are usedto adhere or bind together surfaces.1.3 Testing is conducted in accordance with Test MethodE84.1.4 This practice does not provide pass/fail criteria that canbe used as a regulatory tool.1.5 This practice does not apply to materials for which thetest specimen does not remain in place before and during thetest until maximum flame propagation has occurred.1.6 This practice is not for system evaluation.It is for thecomparison of the materials only.1.7 The results obtained by using this mounting procedureare confined to the materials themselves as tested and are notcomparable to those obtained with materials that are tested ina full tunnel width application.1.8 This fire standard cannot be used to provide quantitativemeasures.1.9 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.10 This standard gives instructions on specimen prepara-tion and mounting,but the fire-test-response method is given inTest Method E84.See also Section 9.1.11 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotesshall not be considered requirements of the standard.1.12 The values stated in inch-pound units are to be re-garded as standard.The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.1.13 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.14 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and SealantsE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE176 Terminology of Fire StandardsIEEE/ASTM SI-10 International System of Units(SI):TheModernized Metric System3.Terminology3.1 DefinitionsFor definitions of terms used in this prac-tice associated with fire issues,refer to the terminology1This practice is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.22 on SurfaceBurning.Current edition approved Nov.1,2017.Published December 2017.Originallyapproved in 2010.Last previous edition approved in 2017 as E269017a.DOI:10.1520/E269017B.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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 contained in Terminology E176.For definitions of terms usedin this practice associated with caulks and sealants refer to theterminology contained in Terminology C717.3.2 Definitions of Terms Specific to This Standard:3.2.1 bead,nin building construction,a strip of appliedsealant,glazing compou
