17、23:2008 (E) 1 Scope 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 initiatio
18、n 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
19、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
20、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 s
21、tructure), 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
22、handling units; air filters; sound attenuators; heat exchangers.

32、poses of this European Standard, the terms and definitions given in EN 12792:2003, together with the following apply. 3.1 shaft space generally encased with building elements, where ventilation ducts and possibly other pipes and cables are located 3.2 support device for a system component, e.g. fire
33、 damper, silencer, etc. to bear a load 3.3 inlet/outlet louvre device, consisting of an assembly of parallel sloping vanes, intended to permit the passage of air, while providing a measure of protection against environmental influences EN 12792:2003, Table 1, number 242 3.4 air control damper elemen

40、e hazard of spreading fire and smoke gases in the case of fire. The materials used in buildings, air distribution systems and their components shall not contribute to the development of fire in accordance with any local requirement. If there are local requirements on the reaction to fire of material
41、s and/or resistance to fire, they shall be observed. 4.2 Design of air distribution systems Air distribution systems shall be turned off in case of fire, unless local requirements allow for other procedures. 4.3 Installation Use the manufacturers instructions for all components. The sealings through
42、 fire resistance enclosures (e.g. ceiling or walls), shall be in accordance with local requirements. 5 Requirements for components intended for fire precautions 5.1 General The performance, which will be achieved by the product in end-use conditions, shall reflect the results of product fire resista
43、nce, fire reaction and smoke control testing, when required, and in accordance with the local regulations, if any. A product shall be tested as a complete assembly with all necessary components which affect fire resistance performance as described in the product standard. Optional accessories can be
44、 available for a product. DIN EN 15423:2008-09 7 EN 15423:2008 (E) Two types of accessories can be provided: fire tested accessory, non fire tested accessory; these need to be studied and calculated inside the complete design of the complete ventilation system. When accessories, modifications, coati
45、ngs etc. affect fire resistance performance, the product shall be tested both with and without these (for example: with and without painting) and conform to relevant standards. NOTE When accessories do not affect fire resistance performance, they can be supplied and fitted on site. Annex B presents
46、relevant standards for each component and their characteristics. 5.2 Inlet/outlet louvres 5.2.1 Component If the louvres are on the external wall of the building no special requirement is needed. 5.2.2 Installation Location of inlet and outlet louvres shall be in accordance with EN 13779. 5.2.3 Comm
47、issioning Conformity with the installation design shall be checked, in particular the minimum distance, defined according to 5.2.2, between the inlet and outlet louvres. 5.2.4 Maintenance Routine A visual check of the louvres shall be performed during ductwork maintenance operations. The air intake
48、or discharge cross-section shall be free from foreign items such as rubbish, birds or insects etc. 5.3 Fans 5.3.1 Fans for ventilation only 5.3.1.1 Component As a fire precaution the fan electric motor shall be equipped with internal or external thermal overload protection. Depending on the applicat
49、ion, it may be used to switch off the motor or to warn of a thermal overload. If necessary fans should be protected, and when they are not connected to a duct they should be protected with metal screens, grids or similar to prevent the entrance of paper, rubbish, and similar foreign material. For fans in air handling units, see also 5.12. 5.3.1.2 Installation Fans shall be located, arranged and installed to afford access for commissioning and maintenance. Fans shall be installed in accordance with the relevant standa
