Abstract

This research covers fire risk classification for construction materials in the countries of the European Union and a full methodological approach to the assessment of the fire hazard, providing requirements, characteristics, and test methods depending on the field of their usage and functional purpose. Application of fireproof coating and constructive fireproofing are considered to be one of the most widespread ways to increase fire safetyof wood constructions. The need to improve approaches tothe development and application of fireproofing ofwood materials, methodological assessment of their efficiency providing fire safety are also specified. The evaluation of the fire behavior of the fireproofed wood samples has been carried out. Two methods were used to get the results: Russian National StandardR 53292-2009 “Fireproof compositions and substances for the wood and materialsbased on it. General requirements. Test methods” and EN 13823:2003 (SBI) method.The purpose of test using a single source of flame (SBI) also involves an application of the larger selection model than the standard test methods in order to get the results, which are much closer to the full-scale reference phase of the fire propagation.Several conclusions have been made:whether it is possible to introduce European standards for the assessment of the construction materials fire risk to the national practice and incorporation of the requirements stipulated in the similar European regulations to the Russian standards.
