Which standard is used to test the air leakage of an air barrier assembly?

The standard used to test the air leakage of an air barrier assembly is ASTM E2357. This standard specifically addresses the determination of air leakage rates in building envelope materials when subjected to air pressure differences, which is crucial for evaluating the performance of air barrier assemblies.

ASTM E2357 encompasses a comprehensive approach to ascertain how effective an air barrier is in restricting air flow, an essential aspect in building energy efficiency and indoor air quality management. By following this standard, practitioners can effectively assess how well an air barrier assembly will perform in real-world conditions, allowing for informed decisions regarding materials and construction practices.

The other standards mentioned focus on different aspects of air and moisture performance. For example, ASTM E283 deals with the rate of air leakage through exterior windows and doors, while ASTM E2178 is intended for testing air permeance of building materials and assemblies. ASTM E1105 is utilized primarily for water penetration testing, not air leakage. Each of these standards plays a different role in building performance assessment, but for explicitly testing air leakage of an air barrier assembly, ASTM E2357 is the relevant choice.
