ÖNORM EN 15650

This document 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) installations in buildings. All fire dampers close automatically in response to raised temperatures indicating fire. This document gives details for the provision of evaluation of conformity and marking of fire dampers. Fire dampers meeting the requirements of this document may be considered suitable for both ducted and non-ducted applications. This document applies to fire dampers with a declared specific fire resistance (Mandate M/117) that are to be used in conjunction with partitions to maintain fire compartments. This document is not applicable to fire dampers that may be used in applications where the presence of process chemicals may affect fire damper performances. This document is not applicable to non-mechanical fire barriers nor to air transfer grilles. 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.
