Abstract. The authors analyze the fire-danger index of building materials (such as roofing materials) in European and Russian regulations. The parameters which were obtained during tests in accordance with standard of roofing materials in European and Russian methods of testing were analyzed. Some of the tests to determine the properties of the fire hazard of building materials are identical. Contributors show that the European standardization system has a much wider range of test methods for determining the properties of fire safety of construction materials. In Russia, for some tests is not unique (the test in a corner room, nonflammability tests, etc.). We concluded that the European standards for building materials are more stringent and also that the correlation between the various indicators missing. We demonstrate significant differences in the European and Russian fire hazard classification of identical roofing materials.
