Test methods for determining the contribution to the fire resistance of structural members - Part 5: Applied protection to concrete/profiled sheet steel composite members
Description:
This European Standard specifies a test method for determining the contribution 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 applicable to all fire protection materials used for the protection of concrete/steel composite members or slab and includes sprayed materials, coatings, cladding protection systems and multi-layer or composite fire protection materials, with or without a cavity between the fire protection material and the concrete/steel composite members or slab.
