Attention is drawn to the possibility that some of the elements of this documen

22、t may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. It is included in a series of European standards planned to cover: - automatic sprinkler systems (EN 12259, EN 12845), - gas extinguishing systems (EN 12094), - powd

23、er systems (EN 12416), - explosion protection systems (EN 26184), - 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 b

24、ound to announce this Technical Specification: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sw

26、revention 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 o

27、f 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 essenti

28、al 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

29、 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

30、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 gi

31、ven 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 shou

32、ld 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

33、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.

34、Similarly, competent technicians should be used in the installation and testing of the equipment.

35、 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 122

36、59-1. 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, comp

37、onents 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 princip

38、les 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. 2 Normative references The following referenced
