43、165 16 0 Foreword These specifications prepared by - the Comit Europen des Assurances (CEA) in the framework of the traditional loss prevention work by European insurers and in line with the EC Commissions group exemption regulation in co-operation with - the European Committee of the Manufacturers
44、of Fire Protection and Safety Equipment and Fire Fighting Vehicles (EUROFEU) are aimed at providing the conditions for a Europe wide uniform high level of personal and property protection. CEA Member Associations have agreed to adopt these specifications and to withdraw any contradicting specificati
45、on of their own. With the explicit endorsement of the - European Fire and Security Advisory Council (EFSAC) it is confirmed that these specifications document the latest state of the art. 1 General 1.1 Scope These Rules specify requirements and give recommendations for the design, installation and m
46、aintenance of fixed fire sprinkler systems in buildings and industrial plant, and particular requirements for sprinkler systems which are integral to measures for the protection of life. The requirements and recommendations of these Rules are also applicable to any addition, extension, repair or oth
47、er modification to a sprinkler system. 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 necessary for sat
48、isfactory performance of sprinkler systems complying with these Rules. The requirements concerning water supplies may be applicable as guidance, to be used with experienced judgement for other fixed, fire fighting systems where no other CEA specifications exist. These Rules do not deal with water sp
49、ray deluge systems. 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. These Rules are 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. They are intended only for fixed fire sprinkler systems in buildings and other premises on land. Although the general principles
