ASTM D7586/D7586M-11 PDF Download

The ASTM D7586/D7586M-11 standard provides a laboratory test method for quantifying air intrusion in low-sloped mechanically attached membrane roof assemblies. The test method is specifically designed to determine the amount of air that infiltrates into the roof assembly under specified negative air pressure differences. It is important to note that the test method is only intended to measure air intrusion in the opaque roof assembly itself, and it does not account for air infiltration through penetrations such as mechanical devices, roof junctions, or terminations.

The standard aims to establish a consistent and reliable method for evaluating the air tightness of low-sloped mechanically attached membrane roofs. By quantifying air intrusion, it helps to assess the effectiveness of the roof assembly in preventing the passage of air, which is crucial for maintaining energy efficiency and preventing moisture problems.
