K90-18017 dampers Shaft installations for both exhaust air and supply air installations are only looked upon as K90-18017 dampers, if the criteria of the building supervision guidelines have been fulfilled. For the installation into walls The connection shall not exceed 350 cm2. The air-handling duct within the shaft shall not exceed 1000 cm2. For the installation into floors The air-handling duct within the shaft shall not exceed 350 cm2. Not suitable for compartmentation (spread of fire from one compartment into another compartment). Temperature increase not exceeding 180 K as a single...

Figure 2 shows the test arrangement for the fireproofing K90-18017 element. The fire-resistant L90 ducts are depending on the diameter mounted into the furnace, e.g. two ducts, in each case one for the smallest diameter and one for the largest. Two fireproofing elements are affixed inside the furnace – one fireproofing element outside the furnace, 2000 mm above the furnace roof. The distance between the fireproofing elements inside and outside the furnace represents the approximate height between floors. The standard time temperature curve is the same as in figure 1, i.e. the fireproofing...

The temperature at the measuring point 500 mm above the furnace roof is in comparison for the BSE, 200 mm diameter, th in the 90 minute only 456 K, i.e. the temperatures of the test specimen outside the furnace are considerably lower than in case of the test specimens in figure 1, where the temperature inside the furnace is in accordance with the standard time th temperature curve in the 90 minute approximately 1000 K. The temperatures acting on fireproofing elements with the addition K90-18017 is considerably lower than on K90 fire dampers. Furthermore, fireproofing elements can only be...
