- Abstract
- The results of a previous study have shown that paints and other thin coverings applid to a flammable base material can provide a new surface of substantially lower flammability than that of the untreated base. Although with coatings of more than 50 mils (0.050-inch) thickness the particular base material used did not appreciably affect the flame spread index of the assembly, it appeared that with thinner finish coatings the base material had an important bearing on the flame spread results obtained. In cases where the coating is intended to be applied to a specified substrate, the surface flammability of the prescribed assembly is required. However, in cases where a particular substrate is not specified and a comparative evaluation of coatings only is desired, a suitable standard substrate material is required.
