Conditions for Nordic harmonisation offire classification of cables: Proposal of implementation of the newEuropean classification system in the building regulations

This report has been prepared for the building authorities in Denmark, Sweden and Norway in cooperation between the fire laboratories in Denmark, Sweden and Norway. The main goal of the project has been to propose how the new European system of reaction to fire classes forelectric cables can be implemented in the Nordic building regulations. This has been approached by exploring the present fire safety status regarding electric cables in the Nordic countries based on different activities. The report gives an overview over fire safety requirements that must be met by cables in the present Nordi cbuilding regulations and in the Nordic regulations for electric installations, and available information on which classes the most used cables will satsfy in the new system. Statistics and experience from fires where cables have been involved in the fire development are also presented. Based on this background, the following proposal of how the euroclass-system for electric cables can be implemented in Nordic building regulations is given: [Graphics][!]
