Flame Spread and Code Conformance Guides for Wood Updated
he work the American Wood Council (AWC) carries out makes it easier for code officials, engineers, designers, and builders to ensure that wood products are used in accordance with the most up-to-date consensus-based building codes. Two AWC publications that support the code and design community have been updated to reflect provisions in the 2018 International Building Code (IBC) and are now available for free use on the AWC website.
T
Design for Code Acceptance (DCA) 1 – Flame Spread Performance of Wood Products Used for Interior Finish Under the building code, interior finish must meet certain requirements that demonstrate its resistance to fire moving across the surface of the material and amount of smoke produced when burning. DCA 1 provides this information for many wood products, giving the flame spread index for a variety of wood species that are normally used as interior finishes for walls and ceilings. Importantly, all wood species and wood panel products listed in DCA 1 are either Class B or Class C, and all have smoked-developed indices less than the limit found in the IBC. Although a bit technical, DCA 1 has also been updated to reflect 2018 International Building Code (IBC) provisions, which require that interior wall and ceiling finish materials be classified based on fire spread and smoke develop indices from testing under the ATSM E84 or UL723 fire tests, and adds references to new ASTM E2579 and E2404 fire test mounting standards as well as Black Spruce 3-ply cross-laminated timber.
