This European Standard specifies a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete filled hollow steel columns. The concrete can be lightweight, normalweight or heavyweight concrete, and of all the strength classes provided for in EN 1994-1-2. The use of a dry sand is considered to be an alternative, conservative approach to the use of wet concrete. A specification for dry sand is given in 5.6.3. The method is applicable to all fire protection systems used for the protection of concrete filled hollow columns and includes sprayed fire protection, reactive coatings, cladding protection systems and multi-layer or composite fire protection materials. If there is no hollow section data from EN 13381-4 or EN 13381-8, this European Standard cannot be used. For passive systems, this data can be derived using the Formula in Annex A of ENV 13381-4:2002. Testing to this European Standard is not required if the fire protection thicknesses for hollow sections derived from EN 13381-4 or EN 13381-8 are to be used for concrete filled hollow sections.
