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.

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.
