CEN/TC 156/WG 9 - Fire precautions for air distribution systems in buildings

This European Standard applies to fire dampers that are to be used in conjunction with fire separating elements to maintain fire compartments. This standard specifies requirements and gives reference to the test methods defined for fire dampers, which are intended to be installed in Heating, Ventilating and Air Conditioning (HVAC) installations in buildings. All fire dampers close automatically in response to raised temperatures indicating fire. 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 standard in conjunction with EN 1366-2 and EN 1363-1 for details of the fire resistance testing and
EN 13501-3 for classification.
Fire dampers meeting requirements of this standard may be considered suitable for both ducted and unducted applications.
This standard has not considered in detail the detrimental and/or corrosive effects that may 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 may be determined using the method described in Annex B.

This document gives guidance for system designers, installers, commissioners and maintenance teams on the incorporation of protective measures for air distribution systems including dual purpose systems for smoke and heat exhaust systems within buildings, to prevent the initiation and the spread of fire, smoke and other by-products of combustion.
This document intends to only support any national (building) regulations, which are the basis of any design of a building or parts of it. It is up to the designer to enquire about the suitability (in particular in legal terms) of a specific solution given in this document (e.g. although "dual purpose systems" are covered in this document, they may not be permitted in some Member States or only in certain types of buildings).
This document applies to all air distribution systems including dual purpose systems (except systems only dedicated to smoke exhaust systems, which are dealt in other European standards) including technical rooms or spaces for the installation of devices to assist in ventilation of a building (e.g. distance of storage of combustible materials to devices and not the fire resistance of the building structure), penetrations, and following components/products used in the system like:
-   inlet/outlet louvres;
-   fans not exposed / exposed to the smoke;
-   air control dampers;
-   ducts;
-   fire control dampers;
-   air terminal devices;
-   anchors and supports;
-   duct fittings;
-   control panels;
-   cables and connections;
-   air handling units;
-   air filters;
-   sound attenuators;
-   heat exchangers.

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.

The product standard will cover the overall requirements for fire rated ducts.

This European Standard applies to fire resistant duct sections, which are to be used in conjunction with partitions to maintain fire compartments in heating, ventilating and air conditioning (HVAC) installations. This standard specifies requirements and gives reference to the test methods defined for fire resistant duct sections, which are intended to be installed in heating, ventilation and air conditioning (HVAC) systems in buildings. It also provides the evaluation of conformity of the products to the requirements of this standard. Furthermore, marking and information on installation and maintenance of these products are also given in this European Standard.
