Designation: E331-00(Reapproved 2009) Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors,and Curtain Walls by Uniform Static Air Pressure Difference11. Scope1.1 This test method covers the determination of the resis-tance of exterior windows.curtain walls, skylights,and doorsto watcr penctration whcn water is applicd to the outdoor faceand exposed edges simultaneously with a uniform static airpressure at the outdloor face higher than the pressure at theindoor face.1.2 This test method is applicable to any curtain-wall area orto windows,skylights,or doors allone.1.3 This tcst mcthod addrcsses water pcnctration through amanufactured assembly.Water that penetrates the assembly.but does not result in a failure as de fied herein. may haveadverse efiects on the pcrformance of contained materials suchas sealants and insulating or laminated glass.This test methoddoes not address these issucs.1.4 The proper use of this lest method requires a knowledgeof the principles of pressure measuremen.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parenthcscs are mathematicalconversions to inch-pound units that are provicd for info
