Flame spread or surface burning characteristics rating is a rating of certain surfaces obtained by laboratory standard test methodology of a material’s propensity to burn rapidly and spread flames. There are several standardized methods of determining flame spread, and they differ from country to country, in a smaller or larger amount.
