Guidelines For The Construction Of Fire Resisting Structural Elements

Results of fire resistance tests carried out on many different types of constructions Have been published by the Fire Research Station, the Timber Research and Development Association (TRADA) and by the Fire Protection Association (FPA). Much information is also readily available from manufacturers, trade organisations and specialist contractors in the fire field. Nevertheless, a need remains for simple generic descriptions of fire-resisting elements. This report sets down guidelines for the fire resistance of elements of structure and includes tables of notional periods of fire resistance based on a consideration of current test data and information. Recent changes made in the formulation of premixed lightweight plasters and work completed on the revisions to BS 476: Part 8 and the British Standard Codes of practice concerning concrete, masonry and timber constructions has necessitated revising both the text and tables of the 1982 edition which is now withdrawn. It is intended to revise the tables as new information becomes available.
