- Abstract
- Plastics are becoming a more and more important part of our daily life, still very little is known about plastics in the fire context. To protect society from the danger which new materials and new structures represent these are tested according to different standard codes. However, Building Codes are inevitably lagging behind and today's standard temperature curves which were developed fifty years ago do not describe the fires which occur in modern compartments furnished with modern materials. A general lack between the results obtained in standard tests and the fire performance of materials and products in actual conditions of use therefore exists. A major purpose for this work has consequently been to study plastic fires in a realistic environment and to develop a more rational base for the structural design of fire exposed structures. This work is concerned with the fully developed period of the fire which is of interest for structural design purposes. One way of carrying out the structural design is to use measured temperature-time curves as a base for the thermal exposure of the structure. Another and better way is to liberate the design from the influences of the experimental conditions and to develop a general design model to be used in any compartment. This is, however, a more difficult task.
