Stanovení rychlosti uvolňování tepla a toxicity zplodin tepelné degradace z podlahové krytiny

Abstract

Bachelor thesis introduces the flammability of floor coverings from natural materials. The selected parameters are the heat release rate (HRR) and the toxicity of the thermal degradation products. The theoretical part deals with the parameter of the rate of heat release, the toxicity of combustion products and selected combustion products. The practical part describes experimental measurements. The first measurement consisted in the determination of HRR by a conical calorimetry method according to ISO 5660-1. The other two measurements were focused on the analysis of the toxicity of combustion products. The paper describes the procedure and course of measurements in the smoke chamber according to ČSN EN ISO 5659-2 and in the thermal decomposition equipment of flammable substances according to DIN 53436. At the end, the results from both measurements are evaluated.
