This Standard establishes contaminated water immersion and drying procedures to be used when determining whether building materials and assemblies are flood damage resistant for applications that comply with the National Flood Insurance Program (NFIP). 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 procedures described in this test method are intended to be used to evaluate the response of materials and assemblies subjected to contaminated water immersion and drying. Requirements for evaluation of other hazards associated with flood damage including, but not limited to, debris impact, flood velocity, wave action, and other factors that would be adverse to continued use of the structure for its intended purpose are outside of the scope of the methods presented herein. 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.
This test method is a means for establishing exposure conditions to prepare specimens for subsequent testing used to classify materials and assemblies with a flood-damage-resistant rating in accordance with the requirements of the National Flood Insurance Program (NFIP). The results obtained using this test method can provide guidance regarding the anticipated flood damage resistance properties of commonly used construction materials. 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).
