    WK69508

    1. Scope

    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.


    Keywords

    fire; equivalency; lumber; floor; joist; framing members

    Rationale

    This standard was developed to provide a uniform approach to meeting the code requirements for fire performance of residential floor assemblies through equivalency to permitted use of unprotected 2x10 dimension lumber or equal-sized structural composite lumber floor joists.

    The title and scope are in draft form and are under development within this ASTM Committee.
