    New Specification for Establishing Fire Equivalency for Floor Framing Members to Unprotected 2x10 Dimension Lumber or Equal-Sized Structural Composite Lumber

    (What is a Work Item?)

    Developed by Subcommittee: D07.05 | Committee D07 | Contact Staff Manager



    WK68131

    1. Scope

    This document 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. The basis and need for the equivalency is Exception 4 to Section R302.13 Fire protection of floors. in the 2015 or 2018 IRC, or Section R501.3 in the 2012 IRC.


    Keywords

    Paints, coatings, chemical treatments, corrosion, durability, exposure, ICAL, factory applied, field applied

    Rationale

    This standard was developed to provide a uniform approach to meeting the model code requirements for equivalency to unprotected 2x10 dimension lumber or equal-sized structural composite lumber floor joists in Exception 4 to Section R302.13 "Fire protection of floors." in the 2015 or 2018 IRC, and Section R501.3 in the 2012 IRC. No current non-proprietary standardization exists, and it will be used by designers and specifiers needing to meet the described sections of code.

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