Abstract

Textile floor coverings especially carpets and rug consider an extremely important role in the spread of flames when a fire occurs، Fire hazards are associated with various properties of combustible materials, including ignition capacity, speed of flame spread, ease of extinguishing, rate of heat release, amount of smoke and toxic gases. It has become clear that the individual characteristic that defines the amount of fire is comparable to the amount of heat release. the main objective of the study is to derive a formula to predict the amount of critical radiant flux expected by the distance burned from textile floor covering, an approach is based on the experimental method, The experimental work focused on measuring the flammability of test samples displayed in table 1. This test method is applicable to all types of carpets, regardless of the manufacturing method (woven or non-woven), the fibers used (natural or synthetic), or the quality of the floor covering (jute or rubber). The test was applied to 27 sample types of carpets were specially manufactured for research with different thicknesses and materials. The study could drive the formula in equation (𝑌 = 0.00014𝑥( − 0.027𝑥 + 1.4) that relate the expected critical energy quantity and the burning distance, where Y is the expected critical energy quantity and X is the burning distance. According to the basic curve of the critical energy required for ignition it was found that a distance of 67 cm achieves the minimum level of the second level (class II) for the amount and magnitude of the critical energy required for ignition (0.22 W/cm2).
