The testing of surface fire retardants

Abstract

The article deals with the importance of testing and using of application of fi re retardants for the needs of fi re protection in practice. The experiment present the testing of test specimens by means of experimental scientifi c method of test of limited fl ame spread in the test bench under laboratory conditions. Based on the measured data are exactly and precisely evaluated different types of surface fi re retardants. On test specimens made by wood were applied the tested fi re retardants, which were directly exposed to open fl ame. The results of the experiment represents and expressed fi re-technical characteristics that describe the behavior of wood specimens during the process of combustion: weight loss, time of ignition, time of spontaneous combustion and time of smolder. The acquired information refl ects the effectiveness of fi re retardants in protection against the fi re.
