Fixed firefighting systems - Automatic sprinkler systems - Part 1: Design, installation and maintenance

This European Standard specifies requirements and gives recommendations for the design, installation and maintenance of fixed fire sprinkler systems in buildings and industrial plants, and particular requirements for sprinkler systems that are integral to measures for the protection of life. This European Standard covers only the types of sprinkler specified in EN 12259 1 (see Annex L). The requirements and recommendations of this European Standard are also applicable to any addition, extension, repair or other modification to a sprinkler system. They are not applicable to water spray or deluge systems. It covers the classification of hazards, provision of water supplies, components to be used, installation and testing of the system, maintenance, and the extension of existing systems, and identifies construction details of buildings which are the minimum necessary for satisfactory performance of sprinkler systems complying with this European Standard. This European Standard does not cover water supplies to systems other than sprinklers. Its requirements can be used as guidance for other fixed firefighting extinguishing systems, provided that any specific requirements for other firefighting extinguishing supplies are taken into account. This European Standard is intended for use by those concerned with purchasing, designing, installing, testing, inspecting, approving, operating and maintaining automatic sprinkler systems, in order that such equipment will function as intended throughout its life. This European Standard is intended only for fixed fire sprinkler systems in buildings and other premises on land. Although the general principles might well apply to other uses (e.g. maritime use). For these other uses additional considerations should be taken into account. The requirements are not valid for automatic sprinkler systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry. Sprinkler system design deviations might be allowed when such deviations have been shown to provide a level of protection at least equivalent to this European Standard, for example by means of full-scale fire testing where appropriate, and where the design criteria have been fully documented.

Fire resistance tests for service installations - Part 1: Ventilation ducts

This document specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including ancillary items such as access panels, attenuators, compensators and control dampers, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This document is used in conjunction with EN 1363-1. Annex A provides general guidance and gives background information. This document is not applicable to: a) ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall (where ducts are located in cavities enclosed by fire-resistant shafts or ceilings); b) ducts containing fire dampers at points where they pass through fire separations; c) one, two or three sided ducts; d) fixing of suspension devices (e.g. anchors) to floors or walls.

Portable equipment for projecting extinguishing agents and firefighting support operations — Hand-held branchpipes for fire service use — Part 3: Smooth bore and/or one fixed spray jet angle branchpipes PN 16

In addition to the common requirements given in EN 15182-1, this document specifies the specific safety and performance requirements and the corresponding test methods, applicale to hand-held branchpipes with smooth bore and/or one fixed spray jet angle with a nominal pressure of 16 bar (1,6 MPa) PN 16, with a maximum flow rate up to 1 000 l/min at a reference pressure of 6 bar (0,6 MPa). NOTE 1 These branchpipes offer no or inadequate protection for firefighters when the spray jet angle is less than 30 ° and therefore are not adapted in high risk firefighting situations such as internal attack. NOTE 2 These branchpipes are not adapted when fighting fires in or near electrical installations when the spray jet angle is less than 30° without written authorization in the manual (safety distances included).

Portable equipment for projecting extinguishing agents and firefighting support operations - Hand-held branchpipes for fire service use - Part 2: Combination branchpipes PN 16

In addition to the common requirements given in EN 15182 1, this document specifies the specific safety and performance requirements and the corresponding test methods, applicable to hand-held combination branchpipes (nozzles), with a nominal pressure of 16 bar (1,6 MPa) PN 16, with a maximum flow rate up to 1 000 l/min at a reference pressure of 6 bar (0,6 MPa).

Portable equipment for projecting extinguishing agents and firefighting support operations — Hand-held branchpipes for fire service use — Part 4: High pressure branchpipes PN 40

In addition to common the requirements given in EN 15182 1, this document specifies the specific safety and performance requirements and the corresponding test methods, applicable to hand-held high pressure branchpipes (nozzles) with a nominal pressure of 40 bar (4,0 MPa) PN 40, with a maximum flow rate up to 250 l/min at a reference pressure of 6 bar (0,6 MPa). These branchpipes are used for example for quick attack lines, building fires, forest fires, etc.
