Abstract
The composition and toxicity of the fire effluent spread in a building during a fire is an important factor in a fire safety assessment. Large-scale tests to investigate the consequences of specific fire scenarios are expensive to conduct and are consequently infrequently made. Modelling of smoke spread in buildings is an alternative method which is often used, but input data on smoke production and effluent composition from specific building products are most often not available.

As a result, contribution to smoke toxicity from building products is often overlooked despite that these products can often be part of fire partitioning elements. An approach to determine such data is to test the building product using a small-scale laboratory method. It is, however, important that the use of small-scale data on fire effluent composition for extrapolation to large-scale fire scenarios is validated and based on sound principles. The work presented in this report concerns small-scale characterization of the effluent content from burning sandwich panel products and the comparison of these results with the fire effluent composition measured during large-scale fire tests.
