EXTENDED APPLICATION OF RESULTS FROM FIRE RESISTANCE TESTS FOR GLAZED NON-LOAD-BEARING CURTAIN WALLING STRUCTURES

This article provides an overview of the new state standard of Russian Federation 55988–2014 “Building structures. Extended application of results from fire resistance tests for glazed non-loadbearing curtain walling structures”. This standard is harmonized with the current European standard EN 15254-4:2008+A1:2011 “Extended application of results from fire resistance tests — Non-loadbearing walls — Part 4: Glazed constructions” and modified (not identical) in relation to it, as in Russia and the European systems of rationing for designs on the fire resistance non-loadbearing glazed walls, there are significant differences. Current Russian standards on methods of fire tests do not address specific design solutions for exterior curtain walls with glazed elements and associated possible scenarios of fire, as well as the orientation of the thermal effect on such a structure. The article lists the parameters and classification for fire resistance of glazed constructions in the regulations of the Russian Federation and the European Union. The basic principles and methods of regulating the increased use of fire-resistant glass constructions.
