This standard provides the test methodology and procedures to demonstrate equivalent fire performance of floor framing members to unprotected 2x10 dimension lumber or equal-sized structural composite lumber floor joists. This standard is applicable to applied treatments or materials used to provide fire resistance to a floor joist, which includes fire-resistive paints, coatings or chemical treatments, or mechanically-attached fire protection materials.
