Basic knowledge of fastening technology Fire protection – Fundamentals. General requirements of building structures for fire protection. Structural installations European standardisation They are to be ordered, erected, changed and brought into commission in such a way that: In accordance with the European Norm DIN EN 13501-1, the classification of fire behaviour of building materials / products is similar to that of DIN 4102. The classifications are, however, much more precise. · The emergence of a fire is prevented from breaking out. · The spread of fire and smoke (spread of fire) is prevented. · In the event of a fire, the rescue of people and animals is possible. · Effective fire-fighting operations are possible. German regulation In Germany, the procedure for construction and operational fire protection are specified by the fire protection standard DIN 4102, the Model Building Ordinance (MBO), Regional Construction Ordinances (LBO) and various trade-specific regulations from professional associations. The following applies as per Section 1 and 2 of DIN 4102: Building materials such as concrete, wood, stone, metal etc., are classified according to their behaviour into flammable or non-flammable building material classes. In addition to, the main classification criteria concerning flammability, flame spread and heat released, e. g. smoke development and dropping behaviour is tested. Fire resistance of components has been tested in Germany in accordance with the European Norm DIN EN 1363 or DIN EN 1365 since 2000. The fire resistance duration is then labelled with the letter R for “Resistance”. The standard temperature-time curve (ETK) of DIN 4102 and ISO 834 is based on a simulation of real fire conditions and forms the evaluation basis that is used worldwide to determine the fire resistance duration. In addition, there are other temperature curves for special fire exposures, e. g. the hydrocarbon curve for destructive fires caused by flammable liquids or the RAB /ZTV tunnel curve (Germany) or the Rijkswaterstaat tunnel curve (the Netherlands), which describe tunnel fires. 16 However, components composed of different flammable and non-flammable materials are not classified into fire classes in building construction but they are evaluated as a complete system according to their fire resistance duration. The fire resistance duration R is indicated in minutes and classified · Components with a fire resistance duration of R30 and R60 are fire-inhibiting. · Fire-resistant, are all components with a fire resistance duration of R90, R120 and R180. Tested systems such as cable, ventilation or duct systems are not only tested for fire resistance, but also for functional capability in the event of fire (e. g. supply lines to sprinkler systems). The fire resistance duration of these systems is e. g. E30 to E120 for electrical cable systems or L30 to L120 for specified ventilation ducts. The anchors that are used to fasten these systems must have at least the same fire resistance duration. fire room temperature [°C] according to two categories: Duration of the fire [min.] (ETC), Temperature curves: RABT/ZTV tunnel curve -- Hydrocarbon curve, Rijkswaterstaat tunnel curve 657
