适用范围：This part of this European Prestandard specifies a test method for determining the contribution of fire protectionsystems to the fire resistance of structural concrete members, for instance slabs, floors, roofs and walls and whichcan include integral beams and columns. The concrete can be lightweight, normalweight or heavyweight concreteand 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 andincludes sprayed materials, coatings, cladding protection systems and multi-layer or composite fire protectionmaterials, when the gap between the fire protection material and the concrete member is less than 5 mm.Otherwise the test methods in prENV 13381-1 or ENV 13381-2, as appropriate, apply.This European Prestandard contains the fire test which specifies the tests which should be carried out todetermine the ability of the fire protection material to remain coherent and fixed to the concrete and to providedata on the temperature distribution throughout the protected concrete member, when exposed to the standardtemperature time curve.In special circumstances, where specified in national building regulations, there can be a need to subject theprotection material to a smouldering curve. The test for this and the special circumstances for its use are detailedin annex A.The fire test methodology makes provision for the collection and presentation of data which can be used as directinput to the calculation of fire resistance of concrete members in accordance with the procedures given inENV 1992-1-2.This European Prestandard also contains the assessment which prescribes how the analysis of the test data shouldbe made and gives guidance to the procedures by which interpolation should be undertaken.The limits of applicability of the results of the assessment arising from the fire test are defined together withpermitted direct application of the results to different concrete structures, densities, strengths, thicknesses andproduction techniques over the range of thicknesses of the applied fire protection system tested.
