This standard currently addresses air barriers, but the roofing community desires to participate in Code accepted quantifiable air leakage testing. Of the three recognized Code standards ASTM E 779, ASTM E 2357 and ASTM E 2178, ASTM E 2357 is the best suited standard that could focus on the roof membrane, while including typical penetrations and terminations. The foundation of ASTM E 2357 well supports the development of a roofing version that could added as an Annex.
