Flame spread, or surface burning characteristics rating,[1] is a ranking derived 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,
I. 1. Instability 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g. calcium. code. I. 2. Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus.
A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.
