BS EN 12101-7:2011EN 12101-7:2011 (E) 5 Introduction This European Standard contains the basic performance and requirements for smoke control duct sections, which are to be used in conjunction with pressure differential systems and smoke and heat control systems. T
26、hey may also be used to pressurise when gas extinguishing systems are used. Particular reference is required to EN 1366-8 and EN 1366-9, which define the fire resistance testing associated with these products and EN 13501-4, which provides details on their fire resistance classification. In addition
27、 to the prevention of transmission of smoke and combustion products from a fire zone, smoke control duct sections are utilised to contain the spillage of otherwise harmful and toxic extinguishing gases from the affected area, and for the control of pressurising and excess air relief within pressuris
28、ation systems. Smoke control systems are designed to fulfil three basic functions. These are: a) the extraction of smoke from a single fire compartment to the outside of the building; b) the extraction of smoke from fire compartments of a building, using a SHEVS connected to one or more fire compart
29、ments. The smoke control duct may or may not pass through other compartments of the building to reach the outside of the building; c) the use of pressurisation to maintain smoke free clear areas. Smoke control ducts are commonly used in smoke and heat control systems. They may serve single compartme
30、nts or a number of different fire compartments. The systems may be dedicated smoke extraction or possibly a combined environmental ventilation/smoke extraction. The smoke and heat control system may remove smoke using either high temperature fans (in accordance with EN 12101-3) or natural ventilator
31、s (in accordance with EN 12101-2).

34、t of the EN 12101 series of harmonised standards and technical reports. The areas for which products supplied to this European Standard are considered applicable include for example: a) commercial premises, b) shopping and retail centres, c) hospitals, d) multi-residential buildings. Smoke control d
35、uct sections are intended for use in the following types of systems, including: a) pressurisation, BS EN 12101-7:2011EN 12101-7:2011 (E) 7 b) pressure relief, c) extraction systems, d) ductwork systems, e) inerting fire suppression systems. It is realised that all the above systems do not address sm
36、oke directly, but similar properties are required of such smoke control ducts to limit leakage in a fire and smoke control situation. BS EN 12101-7:2011EN 12101-7:2011 (E) 8 1 Scope This European Standard applies to smoke control duct sections, placed on the market and intended to operate as part of
37、 a pressure differential system or smoke and heat exhaust system. This standard specifies requirements and gives reference to the test methods defined for smoke control duct sections and their associated components (for example, hangers and other items proven at the time of testing), which are inten
38、ded to be installed in such systems in buildings. It also provides for 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. To avoid duplicat
39、ion, reference is made to a variety of other standards. To this end, this standard is to be read in conjunction with EN 1366-8, EN 1366-9 and EN 1366-1, for details of the fire resistance testing and EN 13501-4 for corresponding classification. This standard has not considered in detail the detrimen
40、tal and/or corrosive effects that may be caused by process chemicals present in the atmosphere, which are drawn through the system intentionally or inadvertently. This European Standard also governs associated components used together with smoke control duct sections such as turning vanes and silenc
41、ers, with the exception of natural and powered smoke ventilators and smoke control dampers, which are covered by separate standards. Ducts for use other than in smoke and heat exhaust/control systems are not covered by this standard. 2 Normative references The following referenced documents are indi
