16、 latest by November 2008, and conflicting national standards shall be withdrawn at the latest by November 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any o
17、r all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary,

19、N 15423:2008 EN 15423:2008 (E) 4 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
20、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 particul
21、ar 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 sy
22、stems (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 resist
23、ance 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
24、 and connections; air handling units; air filters; sound attenuators; heat exchangers.
