Smoke-developed index : ウィキペディア英語版 | Smoke-developed index Smoke-developed index (abbreviated SDI) is a measure of the concentration of smoke a material emits as it burns.〔http://www.kydex.com/briefs/143.pdf〕 Like Flame Spread Index, it is based on an arbitrary scale in which asbestos-cement board has a value of 0, and red oak wood has 100. The SDI is measured using a horizontal test specimen, according to the Steiner tunnel test protocol. The ASTM standard E84 defines a standard test method for surface flame spread and smoke density measurements.〔http://www.astm.org/Standards/E84.htm〕 A smoke-developed index between 0 and 450 is required by IBC section 803.1 for interior wall and ceiling finishes classes A, B and C. ==References==
