1. Scope
This standard prescribes a method to assess the fire performance of roof field vents to the intrusion of wind blown flame and burning ember into the sub-tile and attic areas. The test method applies to off-ridge vent and/or roof field vents otherwise installed in roof field areas. It is applicable to off-ridge vent and/or roof field vents otherwise installed in roof field areas intended for installation with noncombustible clay/concrete tile, composition shingle or other roofing materials when applied as intended for use. The prescribed wind blown flame and burning ember exposures are intended under test conditions to determine resistance to wind blown flame and burning ember penetration into the sub-tile and attic areas. This standard simulates wind blown flame and burning ember exposures common to the areas around wild fire scenarios.
The standard will allow states like California with Wildland Urban Interface (WUI) areas to validate roof field vent manufacturers claims of flame and burning ember resistance. This standard will provide a uniform method for testing roof filed vents that is readily available at numerous testing facilities with reasonable cost.
