Abstract
This report deals with fully developed fires in compartments where the boundary
structure is made of mineral wool and plasterboard. The project was initiated due to new
Swedish regulations (BBR 94) that allow buildings with wood structure to be built more than
two storeys high. The temperature-timecurves in this report are computed according to
authorized methods used in Sweden (method I and method II). The accuracy of the first has
been questioned due to simplifications in the model it is based upon and therefore the methods
are thoroughly analysed. A comparison between fullscale experiments and computer simulated
fires has been carried out. The results indicate that the validity of method I is good. The report
also presents a... (More)

Finally some suggestions are made concerning how further studies should be carried out. (Less)
