1、Designation:E231904(Reapproved 2011)Standard Test Method forDetermining Air Flow Through the Face and Sides ofExterior Windows,Curtain Walls,and Doors Under SpecifiedPressure Differences Across the Specimen1This standard is issued under the fixed designation E2319;the number immediately following th
2、e 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 test method is a modified
3、version of Test MethodE283,and provides a standard laboratory procedure for deter-mining air leakage separately through the face and sides ofexterior windows,curtain walls,and doors under specifieddifferential pressure conditions across the specimen.The testmethod described is for tests with constan
4、t temperature andhumidity across the specimen.NOTE1Detailing buildings with continuous air barriers requires thatthe air barrier plane in a window system be clearly defined.When specialcircumstances dictate that the air barrier be sealed to the window frame ata location other than that used to seal
5、the specimen to the test chamber inthis test method,additional laboratory testing may be required to clarifypotential paths of air flow through the sides of the window frame.Theadapted testing procedure described herein is intended for this purpose.1.2 This laboratory procedure is applicable to exte
6、riorwindows,curtain walls,and doors and is intended to measureonly such leakage associated with the assembly and not theinstallation.The test method can be adapted for the latterpurpose.NOTE2Performing tests at non-ambient conditions or with a tem-perature differential across the specimen may affect
7、 the air leakage rate.This is not addressed by this test method.1.3 This test method is intended for laboratory use.Personsinterested in performing field air leakage tests on installed unitsshould reference Test Method E783.Test Method E783 will notprovide the user with a means of determining air fl
