Designation:D6381/D6381M15(Reapproved 2020)Standard Test Method forMeasurement of Asphalt Shingle Mechanical UpliftResistance1This standard is issued under the fixed designation D6381/D6381M;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 measuring the uplift resistanceof asphalt roofing shingles by mechanical means.It is appli-cable to shingles that use a factory-applied or field-appliedsealant.1.2 There are several types of shingles designed for servicewithout a factory-applied or field-applied sealant.Theseshingles,when applied in accordance with the manufacturersapplication instructions,employ other means to provide resis-tance against the forces generated by the action of wind such asgeometry and shingle construction.Field experience has shownthat these types of shingles function satisfactorily in service.Because there are a variety of these shingle designs,it is notpractical to describe in this test method how to test theseshingles for uplift resistance.The testing of these types ofshingles,therefore,goes beyond the scope of this test method.1.3 This test method describes two procedures for measur-ing shingle uplift resistance.Procedure A employs a speciallydesigned apparatus with a clamping device which facilitateslifting of the edge of the shingle and measuring the forcerequired to break the seal.Procedure B employs a metal“T”section adhered to the weather surface of the shingle tofacilitate application and measurement of a perpendicular forceto break the seal.1.4 It is not prohibited to use this test method over a rangeof sealing time and temperature combinations and testingtemperatures to simulate a variety of actual field use condi-tions.The times and temperatures used shall be stated in thereport.1.5 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.1.6 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.1.7 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 WaterproofingD3462/D3462M Specification for Asphalt Shingles Madefrom Glass Felt and Surfaced with Mineral GranulesD7158/D7158M Test Method for Wind Resistance of As-phalt Shingles(Uplift Force/Uplift Resistance Method)3.Terminology3.1 DefinitionsFor definitions of terms used in this testmethod,refer to 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.3.2.2 sealantas it relates to steep roofing shingles,isdefined as factory-applied or field-applied material designed toseal the shingles to each other under the action of time andtemperature after the shingles are applied to a roof.3.2.3 sealedas it relates to steep roofing shingles,is thecondition of the shingles after the sealant has been activated bythe action 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 1999.Last previous edition approved in 2015 as D6381/D6381M 15.DOI:10.1520/D6381_D6381M-15R20.2For 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 an
