703.3 - Alternative methods for determining fire resistance
The application of any of the alternative methods listed in this section shall be based on the fire exposure and acceptance criteria specified in ASTM E 119 or UL 263. The required fire resistance of a building element, component or assembly shall be permitted to be established by any of the following methods or procedures:
1. Fire-resistance designs
documented in approved sources.
2.
Prescriptive designs of fire-resistance-rated building elements, components or
assemblies as prescribed in Section 720.
3. Calculations in accordance with Section
721.
4. Engineering analysis based
on a comparison of building element, component or assemblies designs having
fire-resistance ratings as determined by the test procedures
set forth in ASTM E 119 or UL 263.
5. Alternative protection methods as allowed
by Section 104.11.
