scope:

This document applies to fire dampers used in conjunction with fire separating elements to maintain fire compartments. This document specifies requirements and gives reference to test methods defined for fire dampers, which are installed in Heating, Ventilating and Air Conditioning (HVAC) installations in buildings. Details are given for the provision of evaluation of conformity and marking of fire dampers. To avoid duplication, reference is made to a variety of other standards. To this end, it is advised to read this document in conjunction with EN 1366-2 for details of the fire resistance testing and EN 13501-3 for classification. Fire dampers meeting the requirements of this document may be considered suitable for both ducted and unducted applications. This document does not consider in detail the detrimental and/or corrosive effects that can be caused by chemical processes present in the atmosphere, which are drawn through the system intentionally or inadvertently and therefore does not apply to fire dampers used in such applications. An indication of salt spray corrosion can be determined using the method described in Annex B. This document is not applicable to non-mechanical fire barriers nor to air transfer grilles.
