Smoke and heat control systems - Part 7: Smoke duct sections

This European Standard applies to smoke control duct sections, placed on the market and intended to operate as part of 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 intended 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 duplication, 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 detrimental 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 silencers, 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.

SIST EN 12101-7:2011

EN 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. They 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 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 pressurisation 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 compartments. 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 compartments 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 ventilators (in accordance with EN 12101-2). SIST EN 12101-7:2011

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 duct sections are intended for use in the following types of systems, including: a) pressurisation, SIST EN 12101-7:2011

EN 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 smoke directly, but similar properties are required of such smoke control ducts to limit leakage in a fire and smoke control situation.

Full details of the structural supports used for the fire test shall be recorded. 4.2.3 Duct sealant materials used in or between smoke control duct sections Sealants are often used to reduce the air/gas leakage from smoke and heat exhaust ventilation systems. Failure of these sealants whilst the smoke and heat exhaust ventilation system is operating in its emergency mode may result in the failure of the duct’s leakage criteria. Full details of the sealants used for the fire test shall be recorded. The following general requirements for duct sealants shall apply. a) The sealants shall be suitable for the environment to which the smoke control duct is to be subject. b) The sealants shall be durable for the proposed life of the smoke control duct section. c) The sealants shall be resistant to mechanical damage during the installation of the smoke control duct section. d) Any deterioration of the sealant shall not cause the smoke control duct section to fail the leakage criteria for the duct classification. 4.2.4 Penetration seals between fire compartments Penetration seals are required to reduce the air/gas leakage between compartments. Failure of these penetration seals, whilst the smoke and heat control system is operating in its emergency mode, may result in the failure of the system to maintain smoke-free areas. Full details of the penetration seals used for the fire test shall be recorded. The following general requirements for penetration seals shall apply. SIST EN 12101-7:2011

EN 12101-7:2011 (E) 12 a) Penetration seals shall maintain the integrity and insulation criteria of the smoke control duct. b) The gap dimension between the inside edge of the supporting construction and the outer perimeter of the smoke control duct section, and hence the sealing details, shall follow the tested method when the smoke control duct section is installed within a building. 4.2.5 Other components Smoke control ducts often contain other components than structural supports and sealants. These shall not cause failure of the smoke extraction system whilst exhausting smoke from the building and shall be tested to meet the same requirements as the duct into which they are installed. Full details of any components used for the fire test shall be recorded. Among these components may be the following equipment:  access doors/panels,  silencers or attenuators to limit noise,  compensators,  turning vanes,  air flow/volume indication transponders,  grilles, to control the direction of air/smoke movement at the terminals of the system. Components shall be tested according to the principles of EN 1366-8 or EN 1366-9 to prove that they do not reduce the performance of the smoke control duct section already tested and classified. They shall be installed in accordance with the manufacturer's instructions for the component and any associated smoke control duct section. 4.3 Fire resistance performance criteria: Multi compartment fire resisting smoke control duct sections 4.3.1 Integrity, insulation, leakage, The assessment of integrity (E) of multi compartment smoke control duct sections, as one of the fire resistance performance characteristics, shall be made on the basis of: a) leakage through the duct section at ambient and after 15 minutes from the start of the fire test; b) the ability of the duct section to maintain its cross section when subjected to the fire test; c) the assessment of collapse of the duct within the furnace, to confirm mechanical stability; d) cracks or openings in excess of given dimensions and ignition of a cotton pad and sustained flaming on the non-exposed side at the perimeter of the duct section junction with the wall or floor or duct (the penetration); e) the suitability for use of the duct section at an under pressure, measured at ambient. When insulation characteristics are proven for multi compartment fire resisting control duct sections, this shall be classified and declared, together with integrity. SIST EN 12101-7:2011

EN 12101-7:2011 (E) 13 A smoke leakage performance requirement is described in EN 13501-4 to allow the (S) classification, and this shall be applied, if the duct section is intended for the end uses where this performance is required (measured continuously after 15 minutes from the start of the fire test. 4.3.2 Fire resistance classification and designation Having achieved the performance criteria in 4.3.1, the multi compartment smoke control duct section shall be classified and designated in accordance with EN 13501-4. The following shall be declared for each multi compartment smoke control duct section: a) integrity class "E", integrity and insulation class "EI" (in accordance to EN 13501-4); b) the additions of the indication(s) of suitability for vertical and/or horizontal use, together with mounting in a floor or in a wall or both, respectively: as ve or ho; c) the addition of the symbol "S" indicates the satisfaction of an extra restriction on leakage; d) the addition of "500", "1000" or "1500" indicates the suitability of use up to these underpressures.
