Influence of Surface Treatment of Wood to the Flame Length and Weight Loss under Load Single-Flame Source

Abstract

The aim of the paper is reaction of fire of two selected wood (spruce and beech wood). These type of woods are used most in the construction industry both as a lining in outdoor or indoor, on the stairs or in the construction of roof trusses. Experiment was focus on testing reaction of fire on two different types of surfaces and the treated and untreated surfaces. The modified surface was abraded by sandpaper and rough surface was only saw wood. The main objective of this study was to observe and compare the length of the flame spread and weight loss of spruce and beech forest in treated and untreated surfaces when applied Single-flame source on the surface of the material.
