for a classification A1.
The specimen is exposed to a diffusive flame of 30 kW. Combustion gases are collected by an exhaust hood for analysis. This gas analysis makes it possible by oxygen depletion to calculate heat release rate from the specimen. Smoke production is assessed by measuring attenuation of a light beam by smoke in the exhaust duct. The burning behaviour of the specimen is observed for flame spread, and the occurrence of burning particles and droplets.
