The 2018 IBC requires interior wall and ceiling finish materials to be classified based on flame spread and smoke-developed indices determined from testing under the ASTM E84 or UL723 test methods. The classifications then set conditions of use for interior finish materials in various occupancies and building locations.<\/p>\n<p>\u201cThe flame spread index for a specific wood product is usually obtained from the manufacturer, but code officials and designers can make use of DCA 1 to determine the flame spread index for many lumber species and various engineered wood products,&#8221; said AWC Manager of Engineering Technology Jason Smart, P.E.<\/p>\n<p>DCA 1\u00a0provides flame spread indices for various wood species across a number of wood products normally used as interior finishes for walls and ceilings. All of the wood species and wood panel products listed in DCA 1 qualify as either Class B or Class C, and all have smoke-developed indices less than the limit required by the IBC.<\/p>\n<p>Updated DCA 1 can be found on the AWC website:\u00a0<a href=\"https:\/\/icm-tracking.meltwater.com\/link.php?DynEngagement=true&amp;H=FcQ5do3Mtm%2F2JnP%2FxXFcY%2BL9mOkU%2Fad4G7kfqxVfSdkEEq1vNf2gy8LSt7iGk%2BsUZpCyW8kmVyy%2BHhKnJkiXhyL8qQhEALat%2BTG8caXMKx9sgK1XR4zyDh%2Byd0x3GGCm&amp;G=0&amp;R=https%3A%2F%2Fwww.awc.org%2Fcodes-standards%2Fpublications%2Fdca1&amp;I=20190708152545.000004c33443%40mail6-41-usnbn1&amp;X=MHwxMDQ2NzU4OjVkMjM2MDc2OTUyZjZhNDQ4YmExOWE5Zjs%3D&amp;S=sos6bquD-h9sDkR0IvCNf324qZNm3XgpH0AkJ0mbJjU\" target=\"_blank\" rel=\"noopener\" data-saferedirecturl=\"https:\/\/www.google.com\/url?q=https:\/\/icm-tracking.meltwater.com\/link.php?DynEngagement%3Dtrue%26H%3DFcQ5do3Mtm%252F2JnP%252FxXFcY%252BL9mOkU%252Fad4G7kfqxVfSdkEEq1vNf2gy8LSt7iGk%252BsUZpCyW8kmVyy%252BHhKnJkiXhyL8qQhEALat%252BTG8caXMKx9sgK1XR4zyDh%252Byd0x3GGCm%26G%3D0%26R%3Dhttps%253A%252F%252Fwww.awc.org%252Fcodes-standards%252Fpublications%252Fdca1%26I%3D20190708152545.000004c33443%2540mail6-41-usnbn1%26X%3DMHwxMDQ2NzU4OjVkMjM2MDc2OTUyZjZhNDQ4YmExOWE5Zjs%253D%26S%3Dsos6bquD-h9sDkR0IvCNf324qZNm3XgpH0AkJ0mbJjU&amp;source=gmail&amp;ust=1562771270691000&amp;usg=AFQjCNH4olC1Y8X2vR-XSRug3R0VDJjrZQ\">awc.org\/codes-<wbr><\/wbr>standards\/publications\/dca1<\/a>.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>LEESBURG, VA. \u2013 The\u00a0American Wood Council\u00a0(AWC) has released an updated version of\u00a0Design for Code Acceptance\u00a0(DCA)\u00a01 &#8211; Flame Spread Performance of Wood Products\u00a0Used for Interior Finish.
