Smoke and heat control systems - Part 6: Specification for pressure differential systems - Kits
This document specifies pressure differential systems designed to hold back smoke at a leaky physical barrier in a building, such as a door (either open or closed) or other similarly restricted openings. It covers methods for calculating the parameters of pressure differential smoke control systems as part of the design procedure. It gives test procedures for the systems used, as well as describing relevant, and critical, features of the installation and commissioning procedures needed to implement the calculated design in a building. It covers systems intended to protect means of escape such as stairwells, corridors and lobbies, as well as systems intended to provide a protected firefighting bridgehead for the Fire Services.
The systems incorporate smoke control components in accordance with the relevant Parts of EN 12101 and kits comprising these and possibly other components (see 3.1.18). This document gives requirements and methods for the evaluation of conformity for such kits.
Rauch- und Wärmefreihaltung - Teil 6: Festlegungen für Differenzdrucksysteme - Bausätze
Anwendungsbereich
Diese Europäische Norm beschreibt Differenzdrucksysteme, die ausgelegt sind, um Rauch an einer undichten Barriere, z. B. an einer Tür (entweder geöffnet oder geschlossen) oder ähnlich eingeschränkte Öffnungen, innerhalb des Gebäudes zurückzuhalten. Es wird davon ausgegangen, dass die Verfahren zur Berechnung der Parameter einer Rauchschutzanlage im Zuge der konstruktiven Auslegung behandelt werden. Diese Europäische Norm führt die angewandten Prüfverfahren für das System auf und beschreibt gleichzeitig die maßgebenden und kritischen Eigenschaften der Installations- und Inbetriebnahmeverfahren, die benötigt werden, um die berechnete Auslegung in einem Gebäude zu erfüllen. Diese Norm behandelt sowohl Systeme, die zur Sicherung von Rettungsmaßnahmen gedacht sind wie z. B. Treppenschächte, Korridore und Vorräume als auch Systeme, die dazu dienen, einen geschützten Brückenkopf für die Brandbekämpfungsmaßnahmen der Feuerwehr zu schaffen.
Systèmes pour le contrôle des fumées et de la chaleur - Partie 6: Spécifications relatives aux systèmes à différentiel de pression - Kits
La présente norme décrit les systèmes à différentiel de pression destinés à retenir les fumées derrière une barrière physique présentant des débits de fuites dans un bâtiment telle qu'une porte (ouverte ou fermée) ou autre ouverture réduite de ce type. Elle couvre les différentes méthodes de calcul des paramètres des systèmes de contrôle des fumées à différentiel de pression comme partie intégrante du mode opératoire de conception. Elle fournit des modes opératoires d'essai pour les systèmes utilisés, et décrit également les caractéristiques pertinentes et essentielles des Modes opératoires d'installation et de mise en service nécessaires pour mettre en �uvre les calculs de conception dans un bâtiment. Elle couvre les systèmes destinés à protéger les moyens d'évacuation tels que les cages d'escaliers, les couloirs et les paliers ainsi que les systèmes destinés à créer un PC avancé protégé pour les pompiers.
Le système comprend des composants de contrôle de la fumée conformément aux parties concernées de l'EN 12101 et des kits intégrant ces composants et éventuellement d'autres composants (voir 3.1.18). Ce document fournit des exigences et des méthodes pour évaluer la conformité de ces kits.

0 Introduction 0.1 Smoke movement in the building This document covers information and requirements on the design, calculation methods, installation and testing of systems intended to limit the spread of smoke by means of pressure differentials. Pressure differential systems can be achieved by two methods: i) pressurization – maintaining a positive pressure within the protected spaces (see Figure 1a), or ii) depressurization – removing hot gases from the fire zone at a lower pressure than the adjacent protected space (see Figure 1b).

Buoyancy experienced by hot gases on the fire storey. Within the fire zone, smoke produced by the fire experiences a buoyancy force owing to its reduced density. In a building this can result in upwards smoke movement between storeys if leakage paths exist to the storey above. In addition, this buoyancy can cause smoke to spread through leakage paths in vertical barriers between rooms, e.g. doors, walls, partitions. The pressure differential typically causes smoke and hot gases to leak out of gaps at the top of a door and cool air to be drawn in through gaps at the bottom. Thermal expansion of hot gases in the fire zone. Fire induced expansion of gases can result in a build up of pressure, accompanied by a flow of hot gases out of the compartment. However, in most cases the initial expansion forces may dissipate quickly and may be ignored. Stack effect throughout the building. In cold ambient conditions, the air in a building is generally warmer and less dense than the external air. The buoyancy of the warm air causes it to rise within vertical shafts in the
