Designation:D7349/D7349M15Standard Test Method forDetermining the Capability of Roofing and WaterproofingMaterials to Seal around Fasteners1This standard is issued under the fixed designation D7349/D7349M;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 qualitative test method determines the capability ofasphalt-based roofing or waterproofing material to seal arounda fastener that penetrates the material and prevent transmissionof liquid water through the material at the penetration underdefined conditions.1.2 This test method is provided for adoption by ASTM orother consensus-based roofing and waterproofing productspecifications as a standardized means to evaluate capability toseal around a fastener.Performance of this test method aftersubjecting the product to conditioning intended to simulateenvironmental stresses and strains is not prohibited.1.3 The text of this test method references notes andfootnotes which provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of the standard.1.4 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.1.5 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.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD3462/D3462M Specification for Asphalt Shingles Madefrom Glass Felt and Surfaced with Mineral GranulesD5147/D5147M Test Methods for Sampling and TestingModified Bituminous Sheet MaterialF1667 Specification for Driven Fasteners:Nails,Spikes,andStaples3.Terminology3.1 DefinitionsFor definitions of terms used in this testmethod,refer to Terminology D1079.4.Summary of Test Method4.1 The capability of asphalt-based roofing or waterproofingmaterials to seal around a penetrating fastener and prevent thepassage of liquid water at the fastener/material interface isdetermined by penetrating the material with a fastener,erectinga water column over that penetration,and monitoring theassembly for water passage for a period of time.4.2 The test method includes protocols that establish levelsfor the test method parameters.The protocol used to evaluatea material is designated in a standard specification for thematerial or by the user of this test method.5.Significance and Use5.1 In some situations,penetration through asphalt-basedroofing or waterproofing materials by fasteners is a requiredpart of the material installation process or occurs duringinstallation of other system components.When fasteners pen-etrate the material as a purposeful and planned part of theconstruction process,it is reasonable to expect that materialsdesigned to limit migration of liquid water at the interfacebetween the penetrating fastener and the material will do so.This qualitative test method provides a means to evaluate theability of a material to limit water migration at fastenerpenetrations when tested under defined conditions.6.Apparatus6.1 Specimen RollerA roller having a mass of 11.8 kg 26lb 60.5%,diameter of 125 mm 5 in.65%,and width of125 mm 5 in.65%.6.2 Water Column ContainerA 4 L 1 gal can with thebottom cut out.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 Dec.15,2015.Published December 2015.Originallyapproved in 2008.Last previous edition approved in 2011 as D7349/D7349M 11.DOI:10.1520/D7349_D7349M-15.2For 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 States1 6.3 SealantAny commercially-available sealant suitablefor sealing the water column container to the roofing orwaterproofing material that will not adversely affect the roofingor waterproofing material.6.4 FastenerThe item that penetrates the test specimen.Use one fastener for each test specimen.Refer to Table 1.6.5 SubstrateThe material to which the test specimen isattached prior to penetration with the fastener.One piece 255by 255 mm 10 by 10 in.65%i
