This European Prestandard specifies a test method for determining the contribu-tion of fire protection systems to the fire resistance of structural concrete/profiled sheet steel composite members or slabs. The concrete can be lightweight, normal-weight or heavy-weight concrete and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC).
The method is applicable to all fire protection systems used for the protection of such structural composite members or slabs and includes sprayed fire protection, coatings, cladding protection systems and multi-layer or composite fire protection materials.
The test method and its assessment procedure are designed to permit direct application of the results to cover a range of thicknesses of the applied fire protection material.
The test method is only applicable to fire protection systems which are fixed directly to the underside of the concrete/steel composite member or slab. Fire protection systems where the fire protection material is not attached directly to the composite member, leading to a continuous cavity between the concrete/steel composite member and the fire protection system of size greater than 5 mm is the subject of prENV 13381-1.
This European Prestandard contains the fire test which specifies the tests which shall be carried out to determine the ability of the fire protection system to remain coherent and fixed to the composite member and to provide data on the temperatures of the steel sheet, throughout the depth of the concrete (for extended application purposes) and the unexposed surface of the concrete, when exposed to the standard temperature/time curve according to the procedures defined herein.
In special circumstances, where specified in national building regulations, there can be a need to subject reactive protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in annex A.
The fire test methodology makes provision for the colle
