This part of this European Standard specifies a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete members, for instance slabs, floors, roofs and walls and which can include integral beams and columns. The concrete can be lightweight, normalweight or heavyweight concrete and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC). The member can contain steel reinforcing bars. The test method is applicable to all fire protection materials used for the protection of concrete members and includes sprayed materials, coatings, cladding protection systems and multi-layer or composite fire protection materials, when the gap between the fire protection material and the concrete member is less than 5 mm. Otherwise the test methods in prEN 13381-1 or prEN 13381-2, as appropriate, apply. This European Standard contains the fire test which specifies the tests which shall be carried out to determine the ability of the fire protection material to remain coherent and fixed to the concrete and to provide data on the temperature distribution throughout the protected concrete member, when exposed to the standard temperature time curve. In special circumstances, where specified in national building regulations, there can be a need to subject the 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 collection and presentation of data which can be used as direct input to the calculation of fire resistance of concrete members in accordance with the procedures given in EN 1992-1-2. This European Standard also contains the assessment which prescribes how the analysis of the test data shall be made and gives guidance to the procedures by which interpolation shall be undertaken. The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different concrete structures, densities, strengths, thicknesses and production techniques over the range of thicknesses of the applied fire protection system tested.
