NFPA 255 Standard Method of Test of Surface Burning Characteristics of Building Materials, utilizes ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials. This test method measures flame growth on the underside of a horizontal test specimen, using the Steiner tunnel test. The result is derivation of a Flame Spread Index (FSI), which is a non-dimensional number which is placed on a relative scale in which asbestos-cement board … http://www.lasfm.org/doc_flamespread.html
