    Rationale

    This standard needs to be updated to require permeance testing using C1809. Additionally, we plan to add a requirement that lap joints be taped in addition to have a pressure sensitive adhesive lap. Finally, all tape used to lap and butt joints will be required to be at least 4 inches wide rather than the previously required 3 inches.
