Further information about planning7.3 Functional endurance7.3 Functional endurance7.3.1 Applicable regulations for busbar trunking systems"Fire prevention devices and fire prevention measures" for electrical installations arerequired in particular in buildings of special types and used for special purposes. Examplesof these types of building include hospitals and public buildings. DIN VDE 0100-560 relatingto buildings and structures for public use and DIN VDE 0100-710 (previously DIN VDE 0107)relating to medical locations specify that the electrical installations in such buildings mustmaintain functional endurance for specific lengths of time even in the event of a fire. Thisrequirement affects the following equipment in particular:● Fire alarm systems● Systems for alerting and providing instructions to visitors and employees● Emergency lighting● Passenger lifts with evacuation circuits that assure functional performance for at least30 minutes in the incoming cable area under full fire conditions● Water pressure boosting systems for the supply of extinguishing water● Ventilating systems of safety stairwells, fire department lifts and machine rooms wherefunctioning must be guaranteed for at least 90 minutesIn order to be able to offer the functional endurance required under the terms of thelegislation for busbar trunking systems, we have for example (in some cases workingtogether with Promat) had the BD2A/BD2C, LDA/LDC, LXA/LXC and LRC busbar trunkingsystems tested successfully at the Materials Testing Institute at Brunswick in Germany.During fire testing the busbar trunking systems concerned (housed in Promatect platecasings of varying thicknesses) were subjected to an external fire load in compliance withthe standard temperature curve (STC) in order to evaluate functional endurance toDIN 4102-12.
