Abstract

On the European market there are several fire retardant products available, which reach class B in the European classification system. The producers promise their fire retardants are effective in reducing different reaction to fire parameters of wood such as the time to ignition, the mass loss rate, the heat release rate, the total heat release, the charring rate and the flame spread. This paper discusses the performance of fire retardant products as pressure impregnated wood, non-intumescence surface coatings and intumescence coatings on Norway spruce (Picea abies). The investigations are performed by using a cone calo- rimeter test according to ISO 5660. The thermal exposures of the investigations are 50kW/m 2 and the standard IS0 834 test curve. As result information about the heat release rate, the mass loss rate and the total heat release for duration of 900 seconds will be presented in this paper.

Highlights

Due to its versatile practicability as building material wood is been used in construction both structurally and as a decorative material

Summary

Introduction

Due to its versatile practicability as building material wood is been used in construction both structurally and as a decorative material. The advantages for using wood as building material are the minimal environmental pollution and a range of excellent technical properties. The disadvantage for using wood is its natural combustibility if exposed to severe fire conditions. The main problems are not clear defined technical requirements in building standards and not existing investigation regarding the long term behaviour under different environmental conditions [1]. Even though some wood products with improved fire performance exhibit excellent fire properties and reach class B in the European standard EN 13501-1 [3]. Another problem is the selection of an unsuitable product for a certain application [2]
