ASTM E283: Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen
Standard: ASTM E283 – Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen
Scope: This test method covers a standard laboratory procedure for determining the air leakage rates of exterior windows, skylights, curtain walls, and doors under specified differential pressure conditions across the specimen. The test method described is for tests with constant temperature and humidity across the specimen.
Applicable Products: All products seeking NAFS compliant reports for fenestration products
Test Procedure Abbreviated: Eliminate extraneous chamber leakage. If this is impractical, measure the amount of leakage with the specimen sealed at the air pressure differences to be exerted during the air leakage tests. Adjust the air flow through the test chamber to provide the specified test pressure difference across the test specimen. When the test conditions are stabilized, record the air flow through the flow meter and the test pressure difference. The recorded measurements shall include the absolute pressure, the temperature, and the relative humidity of the air.
End Result: Verification that the product does or does not meet the performance criteria for Fenestration products. A comprehensive test report will be issued at the end of the conclusion of testing.
