本欧洲标准规定了建筑物和工业厂房内固定式喷水灭火系统的设计、安装和维护要求，并给出了建议，以及对作为生命保护措施组成部分的喷水灭火系统的特殊要求。本欧洲标准仅适用于EN 12259 1中规定的洒水器类型（见附录L）。本欧洲标准的要求和建议也适用于喷水灭火系统的任何添加、扩展、修理或其他修改。它们不适用于喷水或雨淋系统。它包括危险的分类、供水的供应、使用的部件、系统的安装和测试、维护以及现有系统的扩展。并确定符合本欧洲标准的自动喷水灭火系统的最低性能所需的建筑物的施工细节。本欧洲标准不包括除洒水器以外的系统供水。其要求可作为其它固定式灭火系统的指导，但须考虑其它灭火器材的具体要求。本欧洲标准旨在供有关采购、设计、安装、测试、检查、批准、操作和维护自动喷水灭火系统的人员使用，以确保此类设备在其整个使用寿命内按预期运行。本欧洲标准仅适用于建筑物和陆地上其他场所的固定式自动喷水灭火系统。尽管一般原则很可能适用于其他用途（如海事用途）。对于这些其他用途，应考虑其他因素。这些要求不适用于船舶、飞机、车辆和移动消防设备上的自动喷水灭火系统，也不适用于采矿业的地下系统。如果已证明此类偏差至少提供了与本欧洲标准相当的保护水平，例如通过适当的全尺寸火灾试验，并且设计标准已完全记录在案，则可允许出现喷水灭火系统设计偏差。

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.
