Falling parts of external walls claddings in case of fire – ITB test method – results comparison

摘要

Paper presents ITB methodology of testing and assessment of buildings with regard to falling of external walls claddings in case of fire. In the ITB methodology of impact on the facade (external claddings) was assumed in form of flames, generated from a specially designed propane, sand burner with a defined fuel flow rate and laminar airflow from the inside of the furnace resulting in determined temperature and height of the flame. Evaluated criterion is also discussed. Test results of several different types of claddings is analysed and presented in relation to the national Polish regulation along with some technical assessment regarding individual.
