Designation:C1715/C1715M15Standard Test Method forEvaluation of Water Leakage Performance of Masonry WallDrainage Systems1This standard is issued under the fixed designation C1715/C1715M;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.Scope*1.1 This test method describes a standard procedure fordetermining the ability of masonry wall drainage systems tocollect water that penetrates the exterior masonry wythe duringrainstorms and to direct this water back to the exterior surfaceof the wall.1.2 This test method is applicable to wall systems thatcontain an exterior masonry wythe with a drainage zone on theinterior face of the exterior wythe.It is not applicable tosingle-wythe drainage walls.1.3 This test method is not applicable to masonry barrierwalls or other masonry walls that are designed withoutdrainage zones behind the exterior wythe.1.4 This test method covers the application of the testingusing either inch-pound or SI units.The values stated in eitherSI units or inch-pound units are to be regarded separately asstandard.Within the text,the inch-pound units are shown inbrackets.The values stated in each system may not be exactequivalents;therefore,each system shall be used independentlyof the other.Combining values from the two systems mayresult in nonconformance with 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:2C1232 Terminology of MasonryC1601 Test Method for Field Determination of Water Pen-etration of Masonry Wall SurfacesE514 Test Method for Water Penetration and LeakageThrough MasonryE631 Terminology of Building Constructions3.Terminology3.1 DefinitionsFor definitions of terms relating to buildingconstruction used in this test method,see Terminology E631.For definitions of terms relating to masonry,brick and clay tile,and concrete masonry units used in this test method,seeTerminology C1232.3.2 Definitions of Terms Specific to This Standard:3.2.1 back-up wall,nthe portion of the wall systemlocated on the interior side of the drainage zone.3.2.2 drainage zone,nthe region located between theinterior face of the exterior wythe of masonry and the exteriorface of the back-up wall or the water-resistive barrier placed onthe exterior face of the back-up wall to facilitate the flow ofwater to a flashing or water collection system.3.2.2.1 DiscussionThe drainage zone often includes othercomponents such as rigid insulation in addition to devices thatfacilitate the flow of water or prevent mortar from blocking theweeps.3.2.3 flashing,nan impervious material placed at specifiedlocations in a masonry wall drainage system to collect anddirect water penetrating through the exterior wythe of masonryto the exterior face of the exterior wythe of masonry by meansof a weep system.3.2.4 masonry barrier wall,nsingle or multi-wythe ma-sonry wall system that does not contain a drainage zonedirectly behind the exterior masonry wythe.3.2.5 masonry drainage wall,nmasonry wall system de-signed with a drainage zone immediately behind the exteriormasonry wythe that allows water penetrating the masonry toflow down the drainage zone where the water is collected anddiverted by flashing to the exterior face of the exterior wythe orcollected and drained by some other water collection system.3.2.5.1 DiscussionThis wall type includes:masonry cav-ity walls;anchored masonry veneer walls;insulated cavitywalls;and any other masonry wall systems with a drainagezone.1This test method is under the jurisdiction of ASTM Committee C15 onManufactured Masonry Units and is the direct responsibility of SubcommitteeC15.04 on Research.Current edition approved July 1,2015.Published July 2015.Originally approvedin 2009.Last previous edition approved in 2010 as C1715 10.DOI:10.1520/C1715_C1715M-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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.6 masonry wall drainage system,nthe drainage zone,the water resistive barrier(where included),the flashing orother water collection devices,and the weep system in amasonry drainage wall designed to collect water that penetratesthe exterior masonry wythe and direct it back to the exteriorface of the exterior masonry wythe.3.2.7 m
