scope:

This European standard applies to fire dampers that are to be used in conjunction with partitions to maintain fire compartments. This includes dampers that are included in both ducted and un-ducted systems.
This standard specifies requirements and gives reference to the test methods defined for fire dampers, which are intended to be installed in general Heating and Ventilating (HVAC) ducts in buildings.
To avoid duplication reference is made to a variety of other standards. To this end this standard must be read in conjunction with EN 1366-2 and EN1363 for details of the furnace testing.
This standard has not considered in detail the detrimental and or corrosive effects that may be caused by process chemicals present in the atmosphere, which are drawn through the system intentionally or inadvertently.
