Designation: E283-04 (Reapproved 2012) Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows,Curtain Walls, and Doors Under Specified Pressure Differences Across the SpecimenT1. Scope1.1 This test method covers a standard laboratory procedurefor determining the air leakage rates of exterior windows,curain walls.and doors under specified differential pressureconditions across the specimen.The lest method described isfor tests with constant temperature and humidity across thespecimen.1.2This llaboratory procedure is applicable to exteriorwindows,curtain walls,and doors and is intended to measureonly such leakage associated with the assembly and non theinstallation. The test mcthod can be adapted for the latterpurpose.NonE l—Performing tesis at non-ambient conditions or with a tem-perature diflerentisal acrass the specimen may affect 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 ficld air leakage tests on installed unitsshould reference Test Method E783.1.4 Persons using this procedure should bc knowledgcablcin the areas of fluid mechanics. instrumentation
