Ventilation for buildings - Fire precautions for air distribution systems in buildings

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.

Lüftung von Gebäuden - Brandschutz von Lüftungsanlagen in Gebäuden

Dieses Dokument bietet den Anlagenplanern, Anlagenbauern, Inbetriebnehmern und den Instandhaltungs¬teams eine Anleitung zur Anwendung von Schutzmaßnahmen bei Lüftungsanlagen, einschließlich Anlagen mit doppeltem Verwendungszweck Lüften und Entrauchung in Gebäuden, um die Entstehung und Ausbreitung von Bränden, Rauch und sonstigen Nebenprodukten der Verbrennung zu vermeiden.
Dieses Dokument sieht nur die Unterstützung von nationalen (Bau-)Vorschriften vor, die die Grundlage jeglicher konstruktiver Ausführungen eines Gebäudes oder seiner Teile bilden. Es liegt in der Hand des Anlagenplaners, sich nach der Eignung (besonders der rechtlichen Bedingungen) einer spezifischen Lösung, die in diesem Dokument angegeben ist, zu erkundigen (z. B. obwohl "Anlagen mit doppeltem Verwendungszweck" in diesem Dokument behandelt werden, können diese in manchen Mitgliedsstaaten nicht gestattet sein oder nur in bestimmten Gebäudearten).
Dieses Dokument gilt für alle Lüftungsanlagen einschließlich Anlagen mit doppeltem Verwendungszweck (außer für Anlagen, die nur der Rauchfreihaltung dienen, die in anderen Europäischen Normen behandelt werden), einschließlich Lüftungszentralen oder Räumen für den Einbau von Einrichtungen zur Unterstützung der Lüftung eines Gebäudes (z. B. Abstand zwischen der Lagerung brennbarer Materialien und Lüftungsanlagen, nicht jedoch  die Feuerbeständigkeit einer Gebäudestruktur), Durchführungen, sowie für die folgenden in den Anlagen verwendeten Bauteile/Produkte:
- Wetterschutzgitter;
- dem Rauch nicht ausgesetzte/ausgesetzte Ventilatoren;
- Luftregelklappen;
- Luftleitungen;
- Brandschutzklappen;
- Luftdurchlässe;
- Verankerungen und Auflager;
