Scope

This Second Issue of the Outline of Investigation for Ridge Vents, SU 2582, covers requirements intended to evaluate the fire and wind-driven rain performance of roof ridge vents. It was issued to correct an editorial error in 4.1.2.1 and to clarify 8.2 so that the continuation of glowing or flaming on the test room floor is with regards to ridge vent materials (not roof coverings) as it pertains to item (a) of 8.1 and not 7.1.
