Fixed firefighting systems - Water spray systems - Design, installation and maintenance
This standard specifies requirements and gives recommendations for the design, installation and maintenance of fixed deluge water spray systems internal and external to buildings and industrial plant and other premises on land. This standard covers only the use of the types of sprinklers and sprayers specified in EN 12259-1. The requirements and recommendations of this standard are also applicable to any addition, extension, repair or other modification to a water spray system. This standard does not deal with sprinkler systems.
It covers the 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 necessary for the satisfactory performance of water spray systems complying with this standard.
The general principles may well apply to other uses (e.g. maritime use), for these other uses additional considerations will almost certainly have to be taken into account.
For water spray systems covered by this standard the authority shall be consulted.

- foam systems (EN 13565),
- hydrant and hose reel systems (EN 671),
- smoke and heat control systems (EN 12101).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Introduction
Water spray systems can be suitable, in some instances, for extinguishment of fire and in others for
prevention of fire spread, and may be independent of or supplementary to other forms of fire protection.
A water spray system consists of a water supply (or supplies) and one or more sprayers usually open; each
system consists of a control valve set and a pipe array fitted with sprayers.
The design of specific systems may vary considerably, depending on the nature of the hazard and the
basic purposes of protection. Because of these variations and the wide choice in the characteristics of
sprayers, it is assumed that these systems are competently designed, installed and maintained. It is
essential that their limitations as well as their capabilities be thoroughly understood by the designer.
It should not be assumed that the provision of a water spray system entirely obviates the need for other
means of fighting fires and it is important to consider the fire precautions in the premises as a whole.
Special measurement may also be required, for example bounding flammable liquid risks or the protection
drain of flammable liquids spillage.
Structural fire resistance, escape routes, fire alarm systems, particular hazards needing other fire
protection methods, provision of hose reels, fire hydrants and fire extinguishers, etc., safe working and
goods handling methods, management supervision and good housekeeping all need consideration.
It is essential that water spray systems should be properly maintained to ensure operation when required.
This routine is liable to be overlooked or given insufficient attention by supervisors. It is, however,
neglected at peril to the lives of occupants of the premises and at the risk of crippling financial loss. The
importance of proper maintenance cannot be too highly emphasized.
When water spray systems are out of service, extra attention should be paid to fire precautions and the
appropriate authorities informed.
This standard is intended for use by those concerned with purchasing, designing, installing, testing,
inspecting, approving, operating and maintaining water spray systems, in order that such equipment will
function as intended throughout its life.
It is a basic assumption that this standard is for the use of companies employing personnel competent in
the field of application with which it deals. The design, installation and maintenance of water spray systems
should be undertaken only by trained and experienced personnel. Similarly, competent technicians should
be used in the installation and testing of the equipment.
1 Scope
This Technical Specification specifies requirements and gives recommendations for the design, installation
and maintenance of fixed deluge water spray systems internal and external to buildings and industrial plant
and other premises on land. This Technical Specification covers only the use of the types of sprinklers and
sprayers specified in EN 12259-1. The requirements and recommendations of this Technical Specification are
also applicable to any addition, extension, repair or other modification to a water spray system. This Technical
Specification does not deal with sprinkler systems.
It covers the 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 necessary for the satisfactory performance of water spray systems complying with this Technical
Specification.
The general principles may well apply to other uses (e.g. maritime use), for these other uses additional
considerations will almost certainly have to be taken into account.
For water spray systems covered by this Technical Specification the authority shall be consulted.
