1.1”This specification provides the test methodology and procedures to demonstrate that the fire performance of wood-based floor framing members is equivalent to unprotected 2 by 10 dimension lumber or equal-sized structural composite lumber (SCL) floor joists used in interior floor assemblies. This specification is applicable to floor framing members with or without applied treatments or materials used to increase fire resistance, including fire-resistive paints, coatings, or chemical treatments, and including mechanically attached or adhered fire protection materials. It is applicable to any wood-based residential floor framing member product including, but not limited to, prefabricated wood I-joists, open-web wood joists, and trusses with wood flanges and wood or metal web members. In addition, specific requirements for the evaluation of fire-resistive paints, coatings, or chemical treatments used with these floor framing members are included.
Note 1:”This specification provides a method of comparing the fire performance of floor framing members to benchmarked performance of unprotected 2 by 10 dimension lumber or equal-sized SCL floor joists. It has been successfully used to evaluate the performance of prefabricated wood I-joists and wood trusses with various forms of fire protection. While the principles of this specification are generally applicable to all floor framing members, the development of the specification did not consider additional requirements or modifications which may be necessary for the evaluation of floor framing members of other materials, such as steel joists or trusses.
