ANALYSIS OF REQUIREMENTS AND METHODS OF TESTING OF ROOFS AND ROOFING MATERIALS TO FIRE HAZARD
The article is aimed at improving the national regulatory framework on fire safety requirements to create the preconditions for increasing the level of fire safety of construction objects. The authors emphasize that the improvement of the national regulatory framework that regulates fire safety requirements for building structures, products and materials is based today on the introduction of a European fire classification of construction products and building structures in Ukraine, which is established in a series of European standards EN 13501. The analysis of normative documents in force in Ukraine regarding fire safety requirements for roofs and roofing materials and test methods for roofs and roofing materials for fire hazard is given. It has been determined that the requirements and test methods for roofs as part of the design in reaction to fire are not established in normative documents in force in Ukraine. It is emphasized that the test results of roofs executed in accordance with CEN/TS 1187 determine the results related to the results (rules) of direct application. An analysis of requirements and test methods for determining indicators of fire hazard of roofs and roofing materials of normative acts of the countries of the European Union and the United States carried out. It is noted that normative acts of Ukraine regarding the definition of indicators of fire hazard for roofs as constructions do not provide for test methods, which together with the initial result of the test would allow to consider a larger range of one or several parameters of the construction product and the target use parameters. Today, there is no document providing a methodology to optimize the number of tests required to cover the maximum field of application and which would set out the process and development recommendations of extended application areas using the test results obtained from tests on existing methods. The conclusion is made on the expediency of further harmonization of European approaches in the sphere of fire safety of roofs and roofing materials in Ukraine, namely the establishment of requirements for roofs as constructions and the introduction in Ukraine of a method for the expanded application of the results of tests of roof and roofing materials for fire hazard and the introduction of amendments to state construction codes in terms of classification of roofs as structures.
