Field Measurement of Air Leakage Through Installed Exterior Windows and Doors

ASTM E783: Determining Air Leakage Rates of Installed Exterior Windows and Doors

The purpose of the ASTM E783 field measurement test is to determine the leakage associated with the assembly and not the opening between the assemblies. The method is used to create natural environmental conditions that induce air leakage. During the actual test, a chamber is sealed over the interior or exterior face of a testing specimen. The chamber supplies air to or exhausts air at a rate required to maintain test pressure. As the pressure is adjusted, the airflow across the test specimen is recorded.

Conducting ASTM E783 Field Measurements

During the ASTM E783 field measurement of air leakage, a test chamber is fitted to the perimeter of the predetermined test specimen. The test chamber must completely cover the entire assembly. Joints, cracks, and opening for which air leakage is not to be determined must be sealed to prevent leakage from skewing final testing results. The extraneous air leakage through and around the chamber, apparatus, and specimen needs to be measured.

To test the air leakage, the air flow through the test chamber is adjusted to different pressures across the test specimen. When test conditions are stable, the airflow is recorded. Other measurements including barometric pressure, temperature, and relative humidity must be collected near the air intake or exhaust of the air system.

ASTM E783 chamber testing finds the air leakage sites in commercial buildings.
