Standard Test Method for Quantification of Air Leakage in Low-Sloped Membrane Roof Assemblies

Importancia y uso:

5.1 This test method can be useful in understanding the response of low-sloped membrane roof assemblies to air pressure differences induced across the assembly.

5.2 This test method can be useful in understanding the role of different roofing components in providing resistance to air leakage through the roof assembly.

5.3 When applying the results of tests by this test method, note that the performance of a roof or its components, or both, depends on proper installation.

5.4 This test method does not purport to establish all criteria necessary for the consideration of air movement in the design of a roof assembly. Air intrusion in roofing systems is separate and distinct from air leakage in roofing systems. Test Method D7586/D7586M provides an air intrusion test method for mechanically attached roof assemblies. The results are intended to be used for comparison purposes and likely do not represent the field-installed performance of the roof assembly.
