Designation:D7158/D7158M20Standard Test Method forWind Resistance of Asphalt Shingles(Uplift Force/UpliftResistance Method)1This standard is issued under the fixed designation D7158/D7158M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the procedure for calculatingthe wind resistance of asphalt shingles when applied inaccordance with the manufacturers instructions and sealedunder defined conditions.Shingle designs that depend oninterlocking or product rigidity to resist the wind cannot beevaluated using this test method.The method calculates theuplift force exerted on the shingle by the action of wind at aspecified velocity,and compares that to the mechanical upliftresistance of the shingle.A shingle is determined to be windresistant at a specified basic wind speed when the measureduplift resistance exceeds the calculated uplift force for thatvelocity(3-s gust,ASCE 7).1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in nonconformancewith the standard.1.3 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.1.4 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:2D228/D228M Test Methods for Sampling,Testing,andAnalysis of Asphalt Roll Roofing,Cap Sheets,andShingles Used in Roofing and WaterproofingD1079 Terminology Relating to Roofing and WaterproofingD3161/D3161M Test Method for Wind Resistance of SteepSlope Roofing Products(Fan-Induced Method)D3462/D3462M Specification for Asphalt Shingles Madefrom Glass Felt and Surfaced with Mineral GranulesD6381/D6381M Test Method for Measurement of AsphaltShingle Mechanical Uplift Resistance2.2 ASCE Standards:3ASCE 7-16 Minimum Design Loads andAssociated Criteriafor Buildings and Other StructuresASCE 49-12 Wind Tunnel Testing for Buildings and OtherStructures2.3 ANSI/UL Standard:4ANSI/UL 2390-04 Test Method for Wind Resistant AsphaltShingles with Sealed Tabs3.Terminology3.1 Definitions:3.1.1 For definition of terms used in this test method,referto Terminology D1079.3.2 Definitions of Terms Specific to This Standard:3.2.1 sealas it relates to steep roofing shingles,is thebonding that results from the activation of the sealant under theaction of time and temperature.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.02 on SteepRoofing Products and Assemblies.Current edition approved Oct.1,2020.Published October 2020.Originallyapproved in 2005.Last previous edition approved in 2019 as D7158/D7158M 19a.DOI:10.1520/D7158_D7158M-20.2For 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.3Available from American Society of Civil Engineers(ASCE),1801 AlexanderBell Dr.,Reston,VA 20191,http:/www.asce.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.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.13.2.2 sealantas it relates to steep roofing shingles,isdefined as factory-applied or field-applied typically asphalticmaterial designed to seal the shingles to each other under theaction of time and temperature after the shingles are applied toa roof.3.2.3 sealedthe condition of the shingles after they aresubjected to the conditioning procedure described in 10.3.4.Types and Classes of Shingles4.1 Shingles are classified based on their resistance to windvelocities determined from measured data(Section 11),calcu-lations of uplift force(Section 12),and
