6.9 Functional endurance
Applicable regulations
Fire protection equipment and fire protection measures for electrical
installations are particularly necessary for structural installations of special type
and use. Such structural installations include hospitals or places of public
assembly. In this case the electrical installations must, according to
DIN VDE 0100-
560 Structural Installations for Public Assembly and
DIN VDE 0100-710-(precursor DIN VDE 0107
) Medical Locations or the
statutory regulations of the countries, remain operational for certain times, even
in the event of a fire.
This applies in particular to the following installations:
-
Fire alarms
-
Systems for generating alarms and giving instructions to visitors and
employees
-
Safety lighting
-
Passenger lifts with an evacuation circuit which must remain functional for at
least 30 minutes under full-fire conditions in the supply area
-
Water pressure boosting systems for supplying extinguishing water
-
Ventilation units for safety steps, travelling shafts and for machine rooms for
firemen’s lifts for which a minimum functional capability of 90
minutes must
be ensured.
In order to be able to provide the required functional maintenance for busbar
trunking, testing of the unibar H rail system has been successfully carried out in
collaboration with Promat, at the material testing institution in Braunschweig.
For the fire testing, various busbars with a cladding of Promatect boards in
different thicknesses were tested with a fire stress from outside conforming to the
standard time-temperature curve (STTC) to assess the functional maintenance in
accordance with-DIN 4102-12.
