The combustion process is described and analysed based on the experimental results in the context of building fire safety. Data are obtained by means of five standard methods: ISO 5657 ignitability test, ISO 5657 cone calorimeter, ISO 9705 room corner test, EN ISO 1716 small calorimeter, and EN ISO 1182 small furnace. Various categories of building products were tested: cellulose based products (particle boards, plywoods), solid wood, floor coverings, concrete, ceramics, insulations (thermal and/or acoustic), boards (wall/ceiling), mortars, adhesives, and thin coatings. The studied products exhibited very different fire properties from non-combustible to easily combustible. In order to more effectively differentiate non-combustibles and combustibles within building products, the modified heat of combustion was calculated using all test results according to EN ISO 1716 and EN ISO 1182. The revision of criteria for Euro class A1 and A2 is proposed to obtain more realistic reaction-to-fire evaluation. In conclusion, it is advised to use single limit for heat of combustion for A1 and A2 Euro class. The proposed approach for modified heat of combustion is a convenient tool for the fast and cost-effective initial test method for non-combustibility evaluation and seems to be the proper method for distinguishing between non-combustibles and combustibles within building products. It is a better reflection of the real physical process of combustion than the current one. The third A1 criterion is questionable, regarding time to auto-ignition in EN ISO 1182 cylindrical furnace. The measurement for gross heat of combustion by EN ISO 1716 method is proposed for all Euro classes of building products with different limit values.

W referacie przedstawiono założenia, strukturę i cechy funkcjonalne tzw. Interaktywnej Modułowej Platformy Oceny Zagrożenia Pożarowego Budynków, umożliwiającej przetwarzanie danych przy użyciu systemów informatycznych w zakresie algorytmów, mechanizmów i schematów postępowania przy ocenie stopnia zagrożenia pożarowego w budynkach i innych obiektach budowlanych, w oparciu o zasady wiedzy technicznej. Platformie, która będzie dostępna użytkownikom (projektantom, rzeczoznawcom z zakresu ochrony przeciwpożarowej, strażakom itd.) w internecie, będzie towarzyszyło kompendium podstawowej wiedzy w zakresie projektowania budynków pożarowo bezpiecznych, w tym poradnik dotyczący stosowania narzędzi inżynierii bezpieczeństwa pożarowego.

The priority research area, which the article deals with, is the commonly understood buildings fire safety, which should be understood as people safety. It solves the problem of the support for the designers and surveyors in undertaking decisions considering their technical knowledge dealing with various solutions aiming at delivering the appropriate fire safety level of the building or building premises. The article presents the assumptions of the prototype being designed. It is the prototype of the Interactive Modular Platform of Buildings Fire Risk Evaluation which makes data processing possible. It uses IT systems in the field of algorithms ,mechanisms and schemes of conducting while evaluating the fire risk in buildings or other building premises ,using the technical knowledge. The main task , which should be drown up, concerns the interactive modules which could help in making certain calculations or could direct the user to more sophisticated tools. Entering data should be supported by the contextually changeable questions, recommendations as well as the knowledge and references. Such task requires the systematic approach and constructing procedural structure of adequate way of conduct ,appropriate to majority of problems which ,at the moment, are difficult to deal with. The very important task is to construct a net of logical and functional connections between individual modules. To draw up few modules it is required to build material experimental and technological data bases . The data will be used in the system and processed according to the needs.

Konieczność stosowania materiałów ogniochronnych wynika z wymagań stawianych przez przepisy oraz z niedostatecznych właściwości ogniowych materiałów budowlanych użytych do konstrukcji i wykończenia budynku. Jednym z podstawowych wymagań zawartych w art. 5.1 ustawy Prawo budowlane [1] jest zapewnienie budynkom bezpieczeństwa pożarowego.
