A revised version of both standards was published in 2008. There is no obligation to apply the standards merely because they are applicable. An obligation to apply the standards in Germany only exists if they are specified in the building codes („Landesbauordnungen“ – LBO) or in the model building regulations („Musterbauverordnungen“- MBO) of Germany‘s individual federal states. In their LBOs, the 16 federal states refer to the Construction Products Lists („Bauregelliste“) so that products do not have to be tested and approved in each of the individual federal states. The standards listed in the Construction Products Lists automatically apply to all LBOs. As standards EN 179 and EN 1125 are harmonised European standards, these two standards should be included in Construction Products List Part B and would therefore have to be applied. They were included in the Construction Products List, but were removed again some time later. The standards are not included in the current Construction Products List Part B. The federal states currently distance themselves from general mandatory application of EN 179 and EN 1125 for doors in escape routes, but point out that precisely this application can be required by the responsible building control authority on a case-by-case basis. RECOMMENDED APPLICATION With immediate effect, always specify/ install all fittings for escape routes to EN 179 (emergency exit devices) or EN 1125 (panic exit devices). Define the respective type of closure for all relevant doors in the building (emergency exit or panic exit device) and specify them as separate items in the bill of quantities. Separate tender items for the lock and fitting too: Choose the required fittings first and then the relevant approved locks/accessory components. If you are uncertain what to specify for emergency exit or panic doors, to be on the safe side, use a panic bar. DOOR FITTINGS AND LEVER HANDLE EN 179 Emergency Exit Device | General Information Not only the relevant door fittings or lever handles are required for functioning certified emergency exit devices, but also a lock with strike! Several criteria which the door fittings must fulfil are listed below. Depending on the type, the standard differentiates between single leaf and double doorset (two leaf) emergency exit devices, so that other components also belong to the emergency exit device. In the event of an emergency, the emergency exit device should enable the fastest possible evacuation of the room through the emergency exit door with only one hand movement. Regardless of whether the door is locked or only zertifiziert sein. the latch closes the door. The standard is applied to emergency exits at which panic situations are not to be expected. The people in the building are familiar with the exits and their fittings. Emergency exit device according to this standard, Type A HEWI, together with a large number of lock manufacturers, has subjected the R and H technology door fittings to testing and certification. These products have been certified by a recognised certification body and issued with a CE conformity marking. 266 | HEWI Hardware
