This Standard is intended to establish methods for determining the flood damage resistance ratings (Acceptable or Unacceptable) of materials and assemblies for use below the lowest floor of new and substantially damaged structures in accordance with the NFIP requirements for being flood damage resistant. It is intended to apply to construction materials, assemblies, and components that are elements of the building including but not limited to, items such as sheathing, structural elements, insulations, finishes, windows, doors, vents, and other types of fixed or operable openings. This standard shall not supersede other applicable codes or standards. This Standard addresses the effects of flooding on materials and assemblies (such as floor and wall systems) for use below the lowest floor of elevated buildings in Special Flood Hazard Areas. The flood hazards addressed by this Standard include wetting and drying, exposure to elevated temperature and humidity environments which can produce mold growth, and the restorability of those materials and assemblies. Other deleterious effects of floods which are outside the scope of this Standard include but are not limited to: flood borne debris impact, presence of contaminants in flood waters, flood velocity, wave action, scour, erosion, and other factors that would be adverse to continued habitation of the structure for its intended purpose. Although this Standard provides guidelines for acceptable performance under several flood conditions, it does not address the short- or long-term impacts of other flood conditions such as those listed above.
The procedures described in this practice will be intended to be used to classify structural materials and finish materials with a flood damage resistant rating in accordance with the requirements of the National Flood Insurance Program (NFIP). These procedures apply to individual structural materials, individual finish materials, combinations of structural materials and finish materials, and components such as doors and windows. The intended users of this Standard will be those seeking to determine flood damage resistant rating classification of structural materials and finish materials in accordance with the requirements of the National Flood Insurance Program (NFIP).
