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.
