Designation:D8052/D8052M17Standard Test Method forQuantification of Air Leakage in Low-Sloped MembraneRoof Assemblies1This standard is issued under the fixed designation D8052/D8052M;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 provides a laboratory technique fordetermining air leakage in low-sloped membrane roof assem-blies under specified negative air pressures differences.1.2 This test method is intended to measure air leakage of aroof assembly with rooftop penetrations.1.3 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 non-conformancewith the standard.1.4 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.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD7586/D7586M Test Method for Quantification of Air In-trusion in Low-Sloped Mechanically Attached MembraneRoof AssembliesE283 Test Method for Determining Rate of Air LeakageThrough Exterior Windows,Curtain Walls,and DoorsUnder Specified Pressure Differences Across the Speci-menE631 Terminology of Building ConstructionsE1677 Specification forAir Barrier(AB)Material or Systemfor Low-Rise Framed Building WallsE2357 Test Method for Determining Air Leakage of AirBarrier Assemblies2.2 CAN/CSA Standard:3CAN/CSA-A123.21-14 Standard Test Method for the Dy-namic Wind Uplift Resistance of Membrane-roofing Sys-tems3.Terminology3.1 DefinitionsTerms used in this test method are definedin Terminology D1079,Terminology E631,Test Method E283,and Test Method D7586/D7586M.4.Summary of Test Method4.1 The air leakage test consists of installing a roof assem-bly with five typical rooftop penetrations between twochambers,a bottom chamber where the roof assembly isinstalled in a horizontal plane and a top chamber through whichair is exhausted at a rate required to maintain the specifiedpressure difference across the roof assembly,and measuring theresultant air flow through the specimen.Although the roofassembly is tested in horizontal plane,the results are applicableto low slope roofs as defined in Terminology D1079.5.Significance and Use5.1 This test method can be useful in understanding theresponse of low-sloped membrane roof assemblies to airpressure differences induced across the assembly.5.2 This test method can be useful in understanding the roleof different roofing components in providing resistance to airleakage through the roof assembly.5.3 When applying the results of tests by this test method,note that the performance of a roof or its components,or both,depends on proper installation.5.4 This test method does not purport to establish all criterianecessary for the consideration of air movement in the designof a roof assembly.Air intrusion in roofing systems is separateand distinct from air leakage in roofing systems.Test MethodD7586/D7586M provides an air intrusion test method formechanically attached roof assemblies.The results are in-tended to be used for comparison purposes and likely do notrepresent the field installed performance of the roof assembly.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.20 onRoofing Membrane Systems.Current edition approved Jan.15,2017.Published February 2017.DOI:10.1520/D8052_D8052M-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.3Available from Canadian Standards Association(CSA),178 Rexdale Blvd.,Toronto,ON M9W 1R3,Canada,http:/www.csagroup.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.1 6.Test Apparatus6.1 This description of the apparatus is general in nature,and any arrangement of the equipment capable of performingthe test method within the allowable tolerances is permitted.6.2 The major components of the test app
