Smoke extraction duct of
sheet steel
Test certificate P-TUM-411 and
P-3464/ss95-MPA BS
Functional endurance of
120 min at 600'C
General
Essential advantages
. Smoke extraction duct of sheet steel for
the usage within the smoke exhaust
zone or fire compartment, on which no
fire resistance time requlrements have
been placed.
. Tested in accordance with DIN V
18232-6 and prEN 1366-9 600 'C -
120 min (requirement of the standard:
600 "C - 60 min or 400 "C - 120 min).
. category 1and2 temperature stress in
accordance with DIN V 18232-6.
. Pressure level 1 in accordance with
DIN V '18232-6 for an overpressure
inside the smoke extraction ducts,
pressure level 3 in accbrdance with DIN
V 18232-6 for an underoressure inside
the smoke extraction ducts and
pressure level 3 in accordance with DIN
V 18232-O for an overoressure or
underpressure inside the air supply
ducts.
. The smoke extraction ducts are
suitable at ambient temperalure for
-1500 Pa (underpressure) and +500 Pa
(overpressure).
With temperature stress from at the
most 600 'C/120 min up to -500 Pa
(underpressure). For the usage as air
supply duct -1500 Pa (underpressure)
and +1500 Pa (overpressure).
The leakage of the smoke extraction
ducls shall not exceed the value of 3,75
m3/h oer m2 internal surface at -1500
Pa (underpressure).
. Smoke extraction ducts of sheet steel
satisfy the regulatory building products
list A (edition 200111).
