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:

1. the extraction of smoke from a single fire compartment to the outside of the building;

2. 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;

3. 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).

Further guidance on the application of smoke control ducts may be found within the rest 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:

1. commercial premises,

2. shopping and retail centres,

3. hospitals,

4. multi-residential buildings.

Smoke control duct sections are intended for use in the following types of systems, including:

1. pressurisation,

2. pressure relief,

3. extraction systems,

4. ductwork systems,

5. inerting fire suppression systems.

1. 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.Scope

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.

The single compartment smoke control duct section shall demonstrate the following and shall be classified in accordance with EN 13501-4:

1. integrity: this shall be tested in accordance with test method in 5.2 and the integrity classification (E) declared;

2. leakage: this shall be tested in accordance with test method in 5.2 and the leakage classification (S) declared;

4. maintenance of cross section: this shall be tested in accordance with test method in 5.2 and forms part of the integrity classification (E) declared.

Smoke control ducts are required to maintain a clear path for the extract of smoke and heat. To achieve this, the following shall be considered part of the smoke control duct section assembly and their performance in the tests shown in 5.2 recorded.

Structural supports used for smoke control duct sections ensure the mechanical stability and maintenance of cross section. Full details of the structural supports used for the fire test shall be recorded.

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.

1. The sealants shall be suitable for the environment to which the smoke control duct is to be subject.

2. The sealants shall be durable for the proposed life of the smoke control duct section.

3. The sealants shall be resistant to mechanical damage during the installation of the smoke control duct section.

4. Any deterioration of the sealant shall not cause the smoke control duct section to fail the leakage criteria for the duct classification.

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.
