Designation:E214001(Reapproved 2009)Standard Test Method forWater Penetration of Metal Roof Panel Systems by StaticWater Pressure Head1This standard is issued under the fixed designation E2140;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.1.Scope1.1 This laboratory test method covers the determination ofthe resistance to water penetration of exterior metal roof panelsystem sideseams,endlaps,and roof plane penetrations when aspecified static water pressure head is applied to the outsideface of the roof panel.NOTE1This test method is intended to evaluate water-barrier(notwater-shedding)roof system joints and details.These systems are alsoreferred to as hydrostatic roof systems.1.2 This test method is limited to specimens in which thesideseams and attachments are clearly visible and in which thesource of leakage is readily observable.1.3 This test method excludes performance at roof perimeterconditions.1.4 This test method is suitable for evaluating leakage atroof plane penetrations such as fasteners,curbs,pipes,andexpansion joints under a static water pressure head.1.5 The proper use of this test method requires a knowledgeof the principles of water pressure.1.6 The text of this standard includes notes and footnotesexcluding tables and figures,which provide explanatory mate-rial.These notes and footnotes shall not be considered asrequirements of the standard.1.7 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.1.8 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.For specificprecautionary statements,see Section 7.2.Referenced Documents2.1 ASTM Standards:2E631 Terminology of Building ConstructionsE1646 Test Method for Water Penetration of Exterior MetalRoof Panel Systems by Uniform Static Air PressureDifference3.Terminology3.1 DefinitionsFor definitions of general terms relating tobuilding construction used in this method,see TerminologyE631.3.2 Definitions of Terms Specific to This Standard:3.2.1 composite roof systemsroof systems consisting of anexterior metal skin and other components.Factory assembledcomposite panels consist of an exterior metal skin,insulation,and interior metal skin.Field assembled composite systemsconsist of exterior metal skins,underlayment,and a structuralroof deck.3.2.2 panel endlapthe connection between two in-linemetal panels across the width of the panels.3.2.3 panel sideseamthe connection between two adjacentmetal panels along the length of the panels.3.2.4 specimenthe entire assembled unit submitted for testas described in Section 8.3.2.5 water leakagepenetration of water through the planeof the innermost face of the test specimen during the testperiod.3.2.6 water pressure headthe distance from the surface ofthe water to the lowest point or cell of the metal panelspecimen,measured at the locations shown in Fig.1.4.Summary of Test Method4.1 The test consists of sealing and fixing a test specimen toa horizontal support frame,locating vertical water dams aroundthe perimeter of the test specimen,applying a specified static1This test method is under the jurisdiction of ASTM Committee E06 onPerformance of Buildingsand is the direct responsibility of Subcommittee E06.57 onPerformance of Metal Roof Systems.Current edition approved Nov.1,2009.Published January 2010.Originallyapproved in 2001.Last previous edition approved in 2001 as E2140 01.DOI:10.1520/E2140-01R09.2For 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 water head to the outside face of the test specimen andobserving for water leakage on the underside of the testspecimen.5.Significance and Use5.1 This test method is a standard procedure for determiningwater leakage through metal roof panel system sideseams,endlaps,and roof plane penetrations when the roof system issubjected to a specified static water pressure head.NOTE2In applying the results of tests by this method,note that theperformance of a roof or its components or both,is in part a function ofproper installation and adjustment.In service,the performance will alsodepend on the integrity of the supporting construction,roof slope,and onthe resistance of compon
