USE OF THE INTERNATIONAL EXPERIENCE OF APPLICATION BY THE CEN/TS 1187 METHOD FOR DETERMINING METHOD OF THE EXTENDED APPLICATION OF TEST RESULTS OF ROOFS AND ROOFING MATERIALS

Abstract

The article is aimed at further harmonization of the national regulatory framework with international and European regulations on methods of testing roofs and roofing materials on fire safety. The aim of the article is to analyze the international experience of applying test methods in accordance with CEN/TS 1187 to substantiate and determine in Ukraine the feasibility of introducing a separate method of extended application of test results of roofs and roofing materials on fire safety. The analysis of the international experience of application methods of roofs and roofing materials tests is given. The ambiguity of the application of methods in other countries is determined. Each method is independent, without the possibility of replacing one method with another. To determine the characteristics of fire load of ignition sources, the corresponding calculations were performed by four methods of СEN/TS 1187. An analysis of the results of comparative tests conducted by EGOLF during classes on courses on CEN/TS 1187 tests 1 and 2 of four samples. It is emphasized that the repeatability and reproducibility of method 1 are assessed as relatively low. The modeling of heat transfer processes between the heat source and adjacent objects on the field model was carried out using the program FDS (Fire Dynamics Simulator), taking into account the provisions of domestic requirements. The stricter requirements of test method 2 according to CEN/TS 1187 have been confirmed. The expediency of using the second test method in accordance with CEN TS 1187 is emphasized in Ukraine. According to the results of the research, the urgency of setting a new research (development) work on the development of test equipment to determine the extent of the flame on the roofs and roofing materials. In order to harmonize European approaches in the sphere of fire safety of roofs and roofing materials in Ukraine, it is proposed to establish requirements for roofs as structures and make appropriate changes to state building codes in terms of fire classification of roofs.
