21、rformance and requirements for smoke control dampers that are to be used in conjunction with pressure differential systems and smoke and heat control systems. They can also be used to pressurize when gas extinguishing systems are used.Particular reference is made to EN 1366-10, which defines the fur
22、nace testing associated with these products and EN 13501-4, which provides details on their fire resistance classification.In addition to the prevention of transmission of smoke and combustion products from a fire zone, smoke control dampers are utilized to contain the spillage of otherwise harmful
23、and toxic extinguishing gases from the affected area and for the control of pressurizing and excess air relief within pressurization systems.Smoke control systems are designed to fulfil the following basic functions. a) The extraction of smoke from a single fire compartment to the outside of the bui
24、lding.b) The extraction of smoke from fire compartments of a building, using a SHEVS connected to one or more fire compartments. The smoke control system duct may or may not pass through other compartments of the building to reach the outside of the building.c) The use of pressurization to maintain
25、smoke-free clear areas.Smoke control dampers are commonly used in smoke and heat control systems as a means of limiting the number of ducts and high temperature fan units. The ducts into which such smoke control dampers are fitted generally serve a number of different fire compartments. The systems
26、can be dedicated smoke extraction or possibly a combined environmental ventilation/smoke extraction.The smoke and heat control system can remove smoke using either high temperature fans (in accordance with ISO 21927-3) or natural ventilators (in accordance with ISO 21927-2).It may be necessary for a
27、 number of reasons (fire growth, smoke release, etc.) that the open smoke control damper(s) is (are) required to close and that the damper(s) previously closed is (are) required to open.The tests defined in this document are based on the assumption that when smoke is detected within a building, all
28、smoke control dampers other than those serving the fire compartment/smoke reservoir (where the fire has initiated) remain closed or move to the closed position. All smoke control dampers serving the smoke-affected fire compartment/smoke reservoir remain open or move to the open position, and the fan
29、(s) started/natural vents opened.NOTE Figure 1 gives examples of installation positions, but these are not the only positions where dampers can be fitted.

33、of systems, including:1) pressurization;2) pressure relief;3) extraction systems;4) ductwork systems;5) inerting fire suppression systems.It is realized that all the above systems do not address smoke directly, but similar properties are required of such smoke control dampers to limit leakage in a f
34、ire and smoke control situation. ISO 2017 All rights reserved viiBS ISO 21927-8:2017BS ISO 21927-8:2017Smoke and heat control systems Part 8: Smoke control dampers1 ScopeThis document applies to smoke control dampers, placed on the market and intended to operate as part of a pressure differential sy
35、stem or smoke and heat control system. This document specifies requirements and gives reference to the test methods defined for smoke control dampers and their associated components, such as actuators which are intended to be installed in such systems in buildings. Furthermore, provision on marking
36、and information on installation and maintenance of these products are also given.This document distinguishes between two categories of smoke control dampers, i.e. single-compartment smoke control dampers and multi-compartment fire-resisting smoke control dampers.Smoke control dampers covered by this
37、 document can be installed into smoke control system ducts or onto the ducts surface. They can be installed also into a wall, floor or ceiling/roof elements or onto the surface of these elements.NOTE To avoid duplication, reference is made to a variety of other standards. To this end, this document
38、can be read in conjunction with EN 13501-4, EN 1366-10 and ISO 10294-1 for details of the furnace testing.This document does not consider in detail the detrimental and/or corrosive effects that can be caused by process chemicals present in the atmosphere, which are drawn through the system intention
39、ally or inadvertently.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
