IMPROVEMENT OF THE TEST METHOD FOR DETERMINING THE FIRE PROTECTION CAPACITY OF FIRE PROTECTION EQUIPMENT

Abstract

An analysis of the regulatory and legal provision of fire safety regarding the need to treat elements of attic coverings, wooden structures, materials used in interior equipment during the construction and repair of carriages, textile materials for the manufacture of curtains, curtains, upholstery of sofas, etc. with fire protection means is provided. The essence of the classification method of tests, the method of determining the flammability group of substances and materials was studied, and the requirements for fire retardants used in the countries of the European Union were analyzed. A comparison of methods for determining the fire-retardant efficiency of fire-extinguishing materials and determining the flammability group of wood treated with fire-retardant material was carried out. According to the analyzed methods, six fire retardants were tested by applying them to the examined wooden material, three samples of each fire retardant material. Based on the results of the tests and evaluation of the research data, it was established that the tested samples that correspond to certain groups of flammability and one regulatory document belong to different groups of other requirements of regulatory documents. It was also established that there is no additional criterion for evaluating a fire retardant, namely: the temperature of smoke curtains and the time of self-burning, which creates a problem for the classification of fire retardant wood. The conducted studies indicate the need to improve the method of determining the fire-extinguishing capacity with the justification of the need to fix the temperature of flue gases, the time of self-burning (smoldering), the time of conducting tests and the need to classify the II group of fire protection efficiency according to the analyzed standards.
