Designation:E10817An American National StandardStandard Test Methods forFire Tests of Roof Coverings1This standard is issued under the fixed designation E108;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This fire-test-response standard covers the measurementof the relative fire characteristics of roof coverings exposed tosimulated fire sources originating outside the building.It isapplicable to roof coverings intended for installation on eithercombustible or noncombustible roof decks when applied asintended for use.The following test methods are included:1.1.1 Intermittent flame exposure test.1.1.2 Spread of flame test.1.1.3 Burning brand test.1.1.4 Flying brand test.1.1.5 Rain test.1.2 Three classes of fire test exposure are described:1.2.1 Class A Tests are applicable to roof coverings that areexpected to be effective against severe fire exposure,afford ahigh degree of fire protection to the roof deck,do not slip fromposition,and are not expected to present a flying brand hazard.1.2.2 Class B Tests are applicable to roof coverings that areexpected to be effective against moderate fire exposure,afforda moderate degree of fire protection to the roof deck,do notslip from position,and are not expected to present a flyingbrand hazard.1.2.3 Class C Tests are applicable to roof coverings that areeffective against light fire exposure,afford a light degree of fireprotection to the roof deck,do not slip from position,and arenot expected to present a flying brand hazard.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat andflame under controlled laboratory conditions,but does not byitself incorporate all factors required for fire hazard or fire riskassessment of the materials,products or assemblies underactual fire conditions.1.5 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.1.6 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.7 The text of this standard references notes and footnotesthat provide explanatory information.These notes andfootnotes,excluding those in tables and figures,shall not beconsidered as requirements of this standard.2.Referenced Documents2.1 ASTM Standards:2D225 Specification for Asphalt Shingles(Organic Felt)Sur-faced With Mineral Granules(Withdrawn 2012)3D226 Specification for Asphalt-Saturated Organic Felt Usedin Roofing and WaterproofingD227 Specification for Coal-Tar-Saturated Organic FeltUsed in Roofing and WaterproofingD312 Specification for Asphalt Used in RoofingD450 Specification for Coal-Tar Pitch Used in Roofing,Dampproofing,and WaterproofingD1227 Specification for Emulsified Asphalt Used as a Pro-tective Coating for RoofingD2178 Specification for Asphalt Glass Felt Used in Roofingand WaterproofingD2626 Specification for Asphalt-Saturated and Coated Or-ganic Felt Base Sheet Used in RoofingD2898 Practice for Accelerated Weathering of Fire-Retardant-Treated Wood for Fire TestingD3018 Specification for Class A Asphalt Shingles Surfacedwith Mineral Granules1These test methods are under the jurisdiction of ASTM Committee E05 on FireStandards and are the direct responsibility of Subcommittee E05.14 on External FireExposures.Current edition approved Feb.1,2017.Published March 2017.Originallyapproved in 1955.Last previous edition approved in 2016 as E108 161.DOI:10.1520/E0108-17.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright 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 D3158 Specif
